... Scale bars: h = 30 μm, c-g = 20 μm, i-m = 10 μm However, Ellis (1963) Goh and Hyde (1997) accepted nine species, and provided a synopsis, as well as a key to Melanographium species. The genus was reviewed by Somrithipol and Jones (2005), and ten species were considered valid. Members of Melanographium are characterised by unbranched conidiophores generally arising in a group from immersed stromata, polyblastic conidiogenous cells with sympodial proliferation, and holoblastic, 1-celled conidia, frequently reniform and often with a hyaline germ slit (Ellis 1963(Ellis , 1971). ...
... Members of Melanographium are characterised by unbranched conidiophores generally arising in a group from immersed stromata, polyblastic conidiogenous cells with sympodial proliferation, and holoblastic, 1-celled conidia, frequently reniform and often with a hyaline germ slit (Ellis 1963(Ellis , 1971). The length of conidiophores, pattern of conidiophore grouping (single, synnemata, loosely or dense fascicles), conidial shape (straight, curved, or strongly curved), and conidial size are morphological markers to distinguish species in this genus Somrithipol and Jones 2005). However, the taxonomic placement of Melanographium is unresolved, because there was no sequence data available. ...
... Notes: Most Melanographium species were found from palms (Ellis 1963;Goh and Hyde 1997;Somrithipol and Jones 2005) including M. phoenicis, which was collected from Phoenix paludosa (mangrove date palm). Morphological characters of M. phoenicis fit well with Melanographium. ...

... Notes: Melanographium was introduced by Saccardo (1913) to accommodate the hyphomycetous taxon and is typified by M. spleniosporum. Melanographium taxa are saprobes and commonly found on dead or decaying wood, leaves, stems, culms or petioles, mostly on palms (Ellis 1963;Goh and Hyde 1997;Somrithipol and Jones 2005). The genus is characterized by having superficial colonies, unbranched and erect brown conidiophores, polyblastic conidiogenous cells with sympodial proliferation, and holoblastic, reniform, aseptate, brown to dark brown conidia (Ellis 1963(Ellis , 1971. ...
... Notes: Melanographium smilacis was found on dead stems of Smilax perfoliate (Smilacaceae). Melanographium smilacis shares common characters with species in Melanographium such as effused and tufted colonies, loosely or densely fascicle and brown conidiophores and reniform shape, aseptate with dark pigmented conidia (Saccardo 1913;Trotter 1931;Ellis 1963Ellis , 1971Goh and Hyde 1997;Somrithipol and Jones 2005;Hyde et al. 2020b). Phylogenetically, Melanographium smilacis is as a sister lineage with the ex-type strain of M. phoenicis (MFLUCC 18-1481) with 100% MLBS, 1.00 BYPP support (Fig. 158). ...

... Recent fungal biodiversity studies in Thailand have resulted in descriptions of new fungal taxa from various habitats (e.g., banana: Photita et al. , 2002;Magnoliaceae: Phromputtha et al. , 2003;c;palm: Pinnoi et al. , 2003a;Pinruan et al. , 2002;c;Pandanus : Thongkantha et al. , 2003;Zingiberaceae: Bussaban et al. , 2001;. In Thailand there have been several studies focused on fungal communities on wood including freshwater lignicolous microfungi (Sivichai et al. , 1998a;Sivichai & Hywel-Jones, 1999) and terrestrial lignicolous microfungi (e.g., Sihanonth et al. , 1998;Chatanon, 2001;Inderbitzin et al. , 2001;Inderbitzin & Berbee, 2001;Somrithipol & Jones, 2005).

... We are studying the biodiversity of fungi on magnoliaceous plants (e.g. Phromputtha et al. , 2003;c;2005). During examination of terrestrial fungi occurring on Magnoliaceae wood in Doi Suthep-Pui National Park, Thailand, we collected two new species; Acrodictys micheliae , from woody litter of Michelia baillonii (Pierre) Finet & Gagnep., and Dictyosporium manglietiae from Manglietia garrettii Craib. ...
Acrodictys micheliae sp. nov. and Dictyosporium manglietiae sp. nov. are described from dead woody litter of Michelia baillonii and Manglietia garrettii, respectively, collected in Doi Suthep-Pui National Park, Thailand. The new fungi are distinctive and readily separated from those already described in the two genera. Acrodictys micheliae has cylindric-ovoid conidia that are similar in shape to A. septosporioides but smaller in size. Dictyosporium manglietiae is distinct from other species in that the conidia have a hyaline, fusoid to cylindrical appendae produced from the basal cell of the outer row of cells. The new taxa are described and illustrated, and compared with similar species.
... It is believed that the high amount of litter generated in tropical rain forests may support a rich fungal diversity (Hyde, 1997). Recent studies of fungal diversity in Thailand have resulted in a number of new fungal taxa being described from several habitats (banana: Photita et al., 2002; dead leaves of a climber: Somrithipol and Jones, 2005; Magnoliaceae: Kodsueb et al., 2006; Promputtha et al., 2003; 07_Kodsueb.fm Page 1 Jeudi, 14. juin 2007 12:11 12 Colonies effuse, golden-brown. ...
Catenosynnema micheliae gen. et sp. nov. and Oedemium micheliae sp. nov. are described from dead woody litter of Michelia baillonii (Magnoliaceae) collected from Doi Suthep-Pui National Park, Thailand. The novel anamorphic genus, Catenosynnema is characterised by synnematous conidiophores and subhyaline to pale brown, catenate conidia. The genus is similar to the anamorphic genera Seifertia and Sorocybe, both of which have catenate conidia, but differs in that its synnemata are paler in colour and of a different form. The second anamorphic taxon, Oedemium micheliae sp. nov. is distinct from other species in the genus in having conidia in short chains and possessing secondary conidiogenous ampullae. The new taxa are described, illustrated and compared with morphologically similar anamorphic fungi.
... During our study on diversity of palmicolous fungi in northern Thailand, we collected four species of Oxydothis. There have been a number of novel ascomycetous taxa collected from Thailand (Chatmala et al., 2004;Pinruan et al., 2004;Somrithipol and Jones, 2005;Hunter et al., 2006), but this is the first time we identified three new Oxydothis species. These are Oxydothis cyrtostachicola sp. ...
Oxydothis bambusicola sp. nov. is reported from senescent bamboo (Indocalamus sp.) culms collected from Shing Mun Country Park, Hong Kong SAR, P.R. China. This fungus differs from other Oxydothis species in having a relatively massive subapical ascal ring and ascospores with rounded apices with a small amount of mucilage at the apices. The species is compared with previously reported Oxydothis species.

2006). The genus Oxydothis: New palmicolous taxa and phylogenetic relationships within Xylariales. Fungal Diversity 23: 159-179. Oxydothis (Xylariales) is an ascomycete genus, commonly encountered on decaying monocotyledons, such as palms. During our study on diversity of palmicolous fungi in northern Thailand, we encountered three new species of Oxydothis: O. cyrtostachicola, O. inaequalis and O. wallichianensis, and these are described and illustrated in this paper. The three novel species differ from other morphologically similar Oxydothis species in ascomata shape and ostiole position, ascal ring, and ascospore morphology. Phylogenetic affiliations of the new taxa with members of related ascomycete families within the Xylariales are discussed based on morphology and nrDNA sequence data. The phylogenetic relationships of Oxydothis and its familial placement remain obscure based on the 28S nrDNA sequence analyses. Large sub unit nrDNA (28S) gene sequences do not provide significant phylogenetic information concerning the evolutionary relationships of these xylariaceous fungi. ITS nrDNA sequence analyses, however, indicate that Oxydothis is more closely related to members of the Amphisphaeriaceae than Diatrypaceae or Xylariaceae.
The El Foyel Group is defined in the western section (Andean) of the Ñirihuau Basin, Argentina (41°44′S-71°30′W). It consists of three units: the Troncoso, Salto del Macho and Río Foyel formations. The age of the group and of the formations is still controversial. We studied the fungal remains recovered from 14 palynological samples from outcrops in the group with the intention of providing data to solve this problem. The fungal assemblage found is highly diverse and it is mostly composed of spores of different affinities (mainly ascomycetes). We identified 38 species from 18 genera (Anatolinites, Dictyosporites, Didymoporisporonites, Diporicellaesporites, Diporisporites, Dyadosporites, Exesisporites, Foveodiporites, Hypoxylonites, Inapertisporites, Lacrimasporonites, Monoporisporites, Multicellites, Papulosporonites, Pluricellaesporites, Polycellaesporonites, Staphlosporonites and one indet.). Moreover, we propose two new species (Hypoxylonites foyelensis sp. nov. and Pluricellaesporites patagonicus sp. nov.) and a new combination (Dyadosporites annulatus comb. nov.). Most of the species were recovered from samples from the Troncoso Formation (21), while the Salto del Macho and Río Foyel formations showed lesser diversity. Anatolinites subcapsilaris, Dyadosporites subovalis, Inapertisporites subovoideus, Monoporisporites singularovalis and Multicellites ellipticus, biomarkers from the Middle Eocene appeared in the Troncoso and Salto del Salto del Macho formations; whereas indicators of the Eocene-Oligocene, such as Dyadosporites elsikii, Didymoporisporonites panshanensis, Foveodiporites elegans, Lacrimasporonites fusoides and Multicellites leptaleus, were mainly recorded in the Río Foyel Formation. The appearance of the biomarkers mentioned above reinforces the Palaeogene age proposed for the El Foyel Group in previous palynological studies. The record of Hypoxylonites ater (Miocene) in the Salto del Macho formation would expand its range as far back as the Palaeogene.
Cancellidium pinicola sp. nov. is described with illustrations from leaf litter of Pinus massoniana collected in Hong Kong. The fungus sporulated on decaying pine needles incubating on the surface of agar plates, as black, shiny, fan-shaped, superficial multicellular conidia, comprising two wall layers. The morphology of the conidia are typical of Cancellidium and therefore a new species is established. Morphologically, the new species differs from Cancellidium applanatum, the only described species in this genus with respect to the conidial shape and color intensity. In order to investigate possible teleomorphic and phylogenetic relationships of this new taxon, two different regions of the ribosomal gene (18S rDNA and 28S rDNA) were sequenced and analyzed. Parsimony analyses indicate that the isolate may be closely related to other unitunicate ascomycetes especially Podostroma, Hypocrea and Trichoderma (order Hypocreales). Since the isolate was obtained from conidia transferred from the surface of baited plates however, it is equivocal whether this is a pure isolate of C. pinicola.
Submerged wood collected in streams and rivers in north Queensland and several other countries has yielded many new loculoascomycetes. In this paper four new species in three genera of the Melanommatales are described. They are Lophiosphaera rivulicola sp. nov., Melanomma australiense sp. nov., Quintaria aquatica sp. nov. and Quintaria submersa sp. nov. Identification of freshwater ascomycetes is difficult as there presently is no key to genera or species. A key and a pictorial synopsis of genera of freshwater loculoascomycetes from woody substrata are provided.
A new species of Melanographium Saccardo, M. calami N. Srivastava, A.K. Srivastava & Kamal, collected in India on dead leaf sheaths of Calamus tenuis Roxb., is described and illustrated. The history of the genus and the nomenclature of its taxa are reviewed and a key to its species is provided.
