Two interesting fungi belonging to the genus Cordana have been isolated recently in Spain from plant debris. Both are proposed here as new species, described and illustrated. Cordana mercadiana sp. nov. produces 0-1-septate conidia, with a prominent basal scar. Cordana verruculosa sp. nov. differs from the other species of the genus by its unique c...

... The genus Cordana was established by Preuss (1851) to accommodate three species, Cordana polyseptata, Cordana pauciseptata, and Cordana pedunculata, without designation of a type species (Hernández-Restrepo et al. 2014;Hyde et al. 2020b). Cordana is characterised by macronematous, mononematous conidiophores. ...
... Colonies grown on PDA circular, flat, superficial, explanate, with dense, pale mycelium on the surface, white from above, pale brown from below. Notes: The characteristics of conidiogenous cells (Timonin 1940;Hernández-Restrepo et al. 2014;Yang et al. 2022) and conidia, including their colour, septation, shape, and size, are used to distinguish the members of Cordana. Cordana linzhiensis differs from the existing species in having swollen conidiophores, polyblastic, clavate or cylindrical conidiogenous cells, and solitary or acropleurogenous conidia with a hyaline mucoid sheath. ...
... Among the known species, Cordana linzhiensis most closely resembles Cordana crassa in having macronematous, unbranched, straight or flexuous conidiophores, polyblastic, integrated, terminal, sympodial conidiogenous cells, and ovoid, 1septate, dark brown conidia (Tóth 1975), but it differs in its acropleurogenous conidia with a hyaline mucoid sheath (China vs. Europe) (Tóth 1975). Cordana linzhiensis forms a distinct sister clade to Cordana aquatica, Cordana lignicola, and Cordana inaequalis, but it differs from these three species in having clavate, swollen conidiophores and larger mucoid sheath conidia (de Hoog et al. 1983;Hernández-Restrepo et al. 2014) (Figure 4). ...
Lignicolous freshwater fungi form a highly diverse group and are primarily distributed in the classes Dothideomycetes and Sordariomycetes. During an investigation of lignicolous freshwater fungi on the Tibetan Plateau, China, four collections were obtained from submerged wood in freshwater habitats. Morphological studies combined with multi-gene phylogenetic analysis based on ITS, LSU, SSU, and RPB2 indicated that the collected taxa belonged in the orders Conioscyphales and Cordanales in Sordariomycetes. Based on evidence from morpho-molecular analyses, two new species, Conioscypha xizangensis and Cordana linzhiensis, are introduced with descriptions of their hyphomycetous asexual states. Conioscypha xizangensis shows a close phylogenetic relationship with Conioscypha tenebrosa but, unlike that species, has phialidic and integrated conidiogenous cells. Cordana linzhiensis forms a distinct clade within the genus and possesses unique characteristics compared with existing species in having swollen conidiophores, polyblastic, clavate, or cylindrical conidiogenous cells, and solitary or acropleurogenous conidia with a hyaline mucoid sheath. These new discoveries further add to the diversity of freshwater fungi on the Tibetan Plateau. ARTICLE HISTORY
... More conspicuous cylindrical denticles, swollen tips of umbells, and oblong, obovoid, ovoid, or pyriform and septate conidia distinguish C. terrestris from Umbellidion. In addition, C. terrestris is phylogenetically distant from Umbellidion as it belongs to the Sordariomycetes (Hernández-Restrepo et al. 2014). ...
The monotypic genus Umbellidion remains as an incertae sedis in Pezizomycotina. This saprotrophic anamorphic fungus is morphologically distinct and unique, occurring widely in Brazil on several hosts, with only one record in the Caribbean region. During the project “Microfungi from Brazil: looking for new species,” five strains of U. radulans were obtained from decaying leaves of Eucalyptus spp., in the Floresta Estadual Edmundo Navarro de Andrade (FEENA), Rio Claro, São Paulo state, Brazil, and were studied based on their morphology and phylogeny. In this study, we conducted a multigene phylogenetic analysis based on ITS, LSU, SSU, TEF1, and RPB2 sequences of 78 related taxa of Leotiomycetes. Phylogenetic inference showed that strains of Umbellidion form a unique, statistically supported lineage near the base of the Leotiomycetes. Accordingly, a new taxonomic order and family Umbellidiales and Umbellidiaceae were established to classify U. radulans. In addition, U. radulans is epitypified based on a new specimen collected from a Eucalyptus grandis plantation in Brazil.
... asp) [19]. But only 19 species were accepted in the last revision [20], five additional species were added later and three species were transferred into Neocordana Hern.-Restr. and Crous [18,[21][22][23]. ...
... Therefore, we selected 18 strains representing 11 species of Cordana, and 11 strains representing other six related genera and retrieved their respective ITS and LSU sequences from GenBank (Table 1). All published DNA sequences were obtained from relevant studies [20,21]. Humicola limonispora Zhang and Cai was chosen as an outgroup. ...
... However, molecular data have put these two genera in a single monophyletic clade leading to the conclusion that, in this case, "the conspicuous morphological characteristic used to distinguish them have been overemphasized" [42]. Later, Hernández-Restrepo et al. [20] revised the two genera using morphological features in combination with DNA sequence data, and concluded that they were congeneric, and transferred the Pseudobotrytis species to Cordana. ...
During a survey of soil fungal diversity in a rocky desertification area in Yunnan Province, China, a new dematiaceous hyphomycete, Cordana yunnanensis was identified. Morphologically, this species is characterized by macronematous, mononematous conidiophores with discrete, polyblastic conidiogenous cells arranged in a whorl at the apices. Phylogenetic analysis of the combined sequences of the internal transcribed spacer and the large nuclear ribosomal RNA subunit confirmed the phylogenetic position of C. yunnanensis within the genus Cordana, in Cordanaceae.
... The conidia are solitary, acropleurogenous, variably shaped (ovoid, obovoid, ellipsoidal, pyriform, or obpyriform), 0-1-euseptate and seceding schizolytically (Preuss 1851, Hughes 1955, Ellis 1971, Markovskaja 2003, Seifert & al. 2011. Hernández-Restrepo & al. (2014), who expanded the generic concept to include integrate and discrete polyblastic conidiogenous cells that are intercalary nodose and swollen or umbellate at the conidiophore apices, provided a key for 19 accepted species. Thereafter, C. johnstonii M.B. ...
A new species, Cordana sinensis , is described and illustrated from a specimen collected on dead branches of an unidentified broadleaf tree in Jiangxi Province, China. It is characterized by its integrated, polyblastic conidiogenous cells that produce ovoid to obclavate, medially 1–2-septate pale brown, smooth conidia with a slightly prominent hilum. A dichotomous key and a synoptic table to Cordana species, are provided.

Our collection morphologically fits well with asexual morph of Cordana terrestris in having macronematous, erect, unbranched, septate, straight or flexuous, cylindrical conidiophores, terminal, discrete, hyaline conidiogenous cells in groups of 8-14 arranged in umbels, with multiple conidiogenous loci appearing as spinules and light brown, uniseptate, guttulate conidia (Hernández-Restrepo and ). ...
Sordariomycetes is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi mainly characterized by perithecial ascomata and inoperculate unitunicate asci. Freshwater Sordariomycetes play an important role in ecosystems and some of them have the potential to produce bioactive compounds. This study documents and reviews the freshwater Sordariomycetes, which is one of the largest and important groups of fungi in aquatic habitats. Based on evidence from DNA sequence data and morphology, we introduce a new order Distoseptisporales, two new families, viz. Ceratosphaeriaceae and Triadelphiaceae, three new genera, viz. Aquafiliformis, Dematiosporium and Neospadicoides, 47 new species, viz. Acrodictys fluminicola, Aquafiliformis lignicola, Aquapteridospora fusiformis, Arthrinium aquaticum, Ascosacculus fusiformis, Atractospora aquatica, Barbatosphaeria lignicola, Ceratosphaeria aquatica, C. lignicola, Chaetosphaeria aquatica, Ch. catenulata, Ch. guttulata, Ch. submersa, Codinaea yunnanensis, Conioscypha aquatica, C. submersa, Cordana aquatica, C. lignicola, Cosmospora aquatica, Cylindrotrichum submersum, Dematiosporium aquaticum, Dictyochaeta cangshanensis, D. ellipsoidea, D. lignicola, D. submersa, Distoseptispora appendiculata, D. lignicola, D. neorostrata, D. obclavata, Hypoxylon lignicola, Lepteutypa aquatica, Myrmecridium aquaticum, Neospadicoides aquatica, N. lignicola, N. yunnanensis, Ophioceras submersum, Peroneutypa lignicola, Phaeoisaria filiformis, Pseudostanjehughesia lignicola, Rhodoveronaea aquatica, Seiridium aquaticum, Sporidesmiella aquatica, Sporidesmium lageniforme, S. lignicola, Tainosphaeria lunata, T. obclavata, Wongia aquatica, two new combinations, viz.

Chaetomium globosum, Chaetosphaeria cubensis, Ch. myriocarpa, Cordana abramovii, Co. terrestris, Cuspidatispora xiphiago, Sporidesmiella hyalosperma, Stachybotrys chartarum,S. chlorohalonata. A comprehensive classification of the freshwater Sordariomycetes is presented based on updated literature. Phylogenetic inferences based on DNA sequence analyses of a combined LSU, SSU, RPB2 and TEF1α dataset comprising species of freshwater Sordariomycetes are provided. Detailed information including their habitats distribution, diversity, holotype, specimens collected and classification are provided.
... Castañeda & al. as a problematic species due to its conidial shape and septation mode. Cordana currently contains 19 recognized species (Hernández-Restrepo & al. 2014), distinguished primarily by conidial features including shape, size, septation, pigmentation, ornamentation, and presence or absence of a synanamorph (Castañeda-Ruíz & al. 1999, Markovskaja 2003, Hernández-Restrepo & al. 2014. ...

Differs from Cordana verruculosa by its larger smooth conidia; from C. semaniae and C. solitaria by its smaller ellipsoidal to obovoid, pale brown conidia with a prominent basal scar; and further from C. solitaria by lacking a Bispora-like synanamorph. ...
Two new anamorphic fungi, Cordana meilingensis and C. lushanensis,
were collected from dead branches in Jiangxi Province, China. Cordana meilingensis is
characterized by its oblong or cylindrical, medially 1-septate, brown, smooth conidia with
a prominent hilum. Cordana lushanensis is distinguished by its ellipsoidal to obovoid, pale
brown, aseptate, smooth conidia with a prominent basal scar. They are described, illustrated,
and compared with similar taxa.
... Comments: Cordana was described by Preuss (1851) and typified by C. pauciseptata Preuss. This genus has simple, macronematous conidiophores with polyblastic, sympodial conidiogenous cells that are terminal or intercalary, usually inflated, with cylindrical denticles that form 0−1-septate, brown to light brown conidia, with schizolytic secession (Seifert et al. 2011;Hernández-Restrepo et al. 2014). Currently, 19 species of Cordana are included in Cordanaceae (Cordanales, Sordariomycetes), which can be found as saprobes or phytopathogens (Hernández-Restrepo et al. 2014;Zelski et al. 2014). ...

The aim of this study was to investigate the species of conidial fungi associated with leaf litter of Cedrela odorata (Meliaceae), an endangered red cedar species typical of Amazonian terra-firme forests. Conidial fungi were sampled around C. odorata individuals in three forest areas in the municipality of Belém (Pará State, Brazil). A total of 104 species were identified, with 53 new records for the state of Pará, 46 first records for the Brazilian Amazon, including new records for Brazil (Cordana abramovii), for South America (Acarocybiopsis cubitaensis, Xylocladium claviforme) and for the Americas (Dactylaria biguttulata). A review of species of conidial fungi reported on C. odorata is provided, indicating its distribution in Brazil. For each new record in Brazil, South America and the Americas we present a description, illustrations, geographical distribution and taxonomic comments. © 2018, Instituto Nacional de Pesquisas da Amazonia.

The genus Ceratostomella has a long history of taxonomic confusion. While species with evanescent asci have been transferred to the Microascales and Ophiostomatales, the taxonomic status of species with persistent asci has not been completely resolved. In previous studies using DNA sequence data, cultures and morphology, several Ceratostomella spp. were allocated in 13 genera in the Eurotiomycetes and Sordariomycetes. In our study, the systematics of the remaining Ceratostomella spp. with persistent asci is revisited with new collection data, cultures and phylogeny based on novel DNA sequences from six nuclear loci. Bayesian inference and Maximum Likelihood analyses support the monophyly of several wood-inhabiting species formerly classified in Ceratostomella and other unknown morphologically similar taxa and their division into four genera, i.e. Lentomitella, Spadicoides, Torrentispora and the newly described Calyptosphaeria. This robust clade represents the order Xenospadicoidales in the Sordariomycetidae. Comparative analysis of the ITS2 secondary structure revealed a genetic variation among Lentomitella isolates; 11 species were recognised, of which five are newly introduced and two are new combinations. Other taxonomic novelties include four new species and eight new combinations in Calyptosphaeria, Spadicoides, and Torrentispora. Molecular data suggest that Spadicoides is polyphyletic. The core of the genus is positioned in the Xenospadicoidales; Spadicoides s. str. is experimentally linked with sexual morphs for the first time. Based on DNA sequence data, the monotypic genera Xenospadicoides and Pseudodiplococcium are reduced to synonymy under Spadicoides, while Fusoidispora and Pseudoannulatascus are synonymised with Torrentispora. Members of the Xenospadicoidales inhabit decaying wood in terrestrial and freshwater environments and share a few morphological characters such as the absence of stromatic tissue, ascomata with a cylindrical or rostrate neck, similar anatomies of the ascomatal walls, thin-walled unitunicate asci with a non-amyloid apical annulus, disintegrating paraphyses, usually ellipsoidal to fusiform ascospores and holoblastic-denticulate or tretic conidiogenesis. Revised Ceratostomella spp. with persistent asci are listed and the taxonomic status of each species is re-evaluated based on revision of the holotype and other representative material, published details and available phylogenetic data.
... Clade II (0.98 PP, 86 % BS) includes members of Coniochaetales and Cordanales distributed in two well-(1 PP, 99 % BS) and moderate-supported (0.97 PP, 77 % BS) subclades. Two species of Cordana were collected from plant debris during our sampling and described as C. mercadiana and C. verruculosa (Hernández- Restrepo et al. 2014b). Only C. verruculosa is included in the present phylogenetic analysis. ...
During a survey of saprophytic microfungi on decomposing woody, herbaceous debris and soil from different regions in Southern Europe, a wide range of interesting species of asexual ascomycetes were found. Phylogenetic analyses based on partial gene sequences of SSU, LSU and ITS proved that most of these fungi were related to Sordariomycetes and Dothideomycetes and to lesser extent to Leotiomycetes and Eurotiomycetes. Four new monotypic orders with their respectively families are proposed here, i.e. Lauriomycetales, Lauriomycetaceae; Parasympodiellales, Parasympodiellaceae; Vermiculariopsiellales, Vermiculariopsiellaceae, and Xenospadicoidales, Xenospadicoidaceae. One new order and three families are introduced here to accommodate orphan taxa, viz. Kirschsteiniotheliales, Castanediellaceae, Leptodontidiaceae, and Pleomonodictydaceae. Furthermore, Bloxamiaceae is validated. Based on morphology and phylogenetic affinities Diplococcium singulare, Trichocladium opacum and Spadicoides atra are moved to the new genera Paradiplococcium, Pleotrichocladium and Xenospadicoides, respectively. Helicoon fuscosporum is accommodated in the genus Magnohelicospora. Other novel genera include Neoascotaiwania with the type species N. terrestris sp. nov., and N. limnetica comb. nov. previously accommodated in Ascotaiwania; Pleomonodictys with P. descalsii sp. nov. as type species, and P. capensis comb. nov. previously accommodated in Monodictys; Anapleurothecium typified by A. botulisporum sp. nov., a fungus morphologically similar to Pleurothecium but phylogenetically distant; Fuscosclera typified by F. lignicola sp. nov., a meristematic fungus related to Leotiomycetes; Pseudodiplococcium typified by P. ibericum sp. nov. to accommodate an isolate previously identified as Diplococcium pulneyense; Xyladictyochaeta typified with X. lusitanica sp. nov., a foliicolous fungus related to Xylariales and similar to Dictyochaeta, but distinguished by polyphialidic conidiogenous cells produced in setiform conidiophores. Other novel species proposed are Brachysporiella navarrica, Catenulostroma lignicola, Cirrenalia iberica, Conioscypha pleiomorpha, Leptodontidium aureum, Pirozynskiella laurisilvatica, Parasympodiella lauri and Zanclospora iberica. To fix the application of some fungal names, lectotypes and/or epitypes are designated for Magnohelicospora iberica, Sporidesmium trigonellum, Sporidesmium opacum, Sporidesmium asperum, Camposporium aquaticum and Psilonia atra.
... Ecologically, Cordana species can be separated into two groups, namely phanerogam leaf-inhabiting species (saprobic or pathogenic) or saprobic on rotten wood or in soil (de Hoog et al. 1983). Saprobic species as C. abramovii Seman & Davydkina (1983: 20), C. bisby (Timonin) M. Hern.-Rest., Gené & Guarro (2014: 106), C. ellipsoidea de Hoog (1973: 22), C. inaequalis S. Hughes (1983: 246) (Hernández-Restrepo et al. 2014, Zelski et al. 2014. Nevertheless, plant pathogenic species such as C. musae, C. johnstonii, and C. versicolor cluster apart, and are phylogenetically unresolved. ...
... Réblová et al. 1999). Recent molecular studies reported the family to be phylogenetically closely related to the Coniochaetales (Réblová & Winka 2000, Huhndorf et al. 2004, Réblová & Seifert 2007, Hernández-Restrepo et al. 2014, Zelski et al. 2014. Coniochaetales includes only one family Coniochaetaceae, with members characterized by ascomata lacking of stromatic tissue, ascospores with elongated germ slits and phialidic asexual morphs (Huhndorf et al. 2004), clearly different from members of Cordanaceae that can have a basal stroma, ascospores without germ slits and polyblastic asexual morphs. ...
... In our phylogenetic tree based on LSU sequences (Figure 1), cordana-like strains isolated from symptomatic leaves of Musa from different countries constituted a distant clade in Pyriculariaceae (Magnaporthales). Recently phylogenetic studies (Hernández-Restrepo et al. 2014) demonstrated that members of Cordana occupy a monophyletic clade in the family Cordanaceae, as the sister clade of Coniochaetales in Sordariomycetes. Cordanales is here erected for the single family Cordanaceae. ...
Cordana leaf spot of banana is shown to be associated with several species of a new genus described here as Neocordana gen. nov. Furthermore, Neocordana belongs to Pyriculariaceae (Magnaporthales) rather than Cordanaceae where the type species of Cordana, C. pauciseptata resides. Neocordana is established to accommodate Cordana musae, C. johnstonii, C. versicolor, and a previously undescribed species, N. musicola, which is morphologically and phylogenetically distinct. Neo-cordana species are found to be associated with leaves of Musa spp. (Musaceae) and Canna denudata (Cannaceae). Based on these results, Cordanaceae is best recognized in a separate order, established here as Cordanales ord. nov.
