Similar to cacao pod rot, cherelle wilt decreases production from cacao fields. Among all known fungal pathogens of the cacao, Colletotrichum spp. are common infectious agents that affect the cherelles and pods of cacao; thus, cacao diseases are often classified by stage. Therefore, knowing whether these pathogens are common in both fruit stages is necessary for implementing disease control measures. Symptoms of cherelle wilt were found in cacao plants in Pangasinan, Philippines, in 2022. The fungal strain obtained from the lesion was found to be pathogenic towards cherelles, but not towards pods. The strain was classified as an unknown species belonging to the gigasporum species complex, based on the morphological and molecular phylogenetic analyses of ITS, GAPDH, CHS1, ACT, and TUB2. We propose Colletotrichum kapreanum sp. nov. as a causal agent of cacao cherelle wilt, but not pod rot.
... The genus Colletotrichum Corda (Sordariomycetes, Glomerellales, Glomerellaceae) includes widely distributed phytopathogenic fungi that hold particular significance for agriculture (Zhang et al., 2006;Réblová et al., 2011). The crop diseases caused by these fungi, mainly anthracnoses, blights, and rots, lead to significant economic losses worldwide. ...
... Lumbsch and Huhndorf (2010) accepted four orders and 18 families in Hypocreomycetidae. Boonyuen et al. (2011) and Réblová et al. (2011) introduced Savoryellales and Glomerellales in Hypocreomycetidae, respectively. Maharachchikumbura et al. (2015) re-evaluated the classification of Sordariomycetes based on LSU, SSU, tef1-α and rpb2 sequence data. ...
... Glomerellales was established by Réblová et al. (2011) with three families viz. Australiascaceae, Glomerellaceae and Reticulascaceae based on multi-locus phylogenetic analysis. ...
... Ascocodinaea differs from Reticulascaceae in having unbranched conidiophores and broadly ellipsoidal or inequilateral, 0-1-septate conidia, whereases, conidiophores of Reticulascaceae are branched or unbranched and conidia are pyriform to cylindrical, 1-or multi-septate. In addition, conidiogenous cells of Ascocodinaea have proliferating percurrent growth; this was not observed in Reticulascaceae (Réblová et al. 2011). Malaysiascaceae differs from Australiascaceae in having bi-seriate, hyaline ascospores that become 1-septate and pale brown after discharge. ...
Hypocreomycetidae is a highly diverse group with species from various habitats. This subclass has been reported as pathogenic, endophytic, parasitic, saprobic, fungicolous, lichenicolous, algicolous, coprophilous and insect fungi from aquatic and terrestrial habitats. In this study, we focused on freshwater fungi of Hypocreomycetidae which resulted 41 fresh collections from China and Thailand. Based on morphological and phylogenetic analyses, we identified 26 species that belong to two orders (Hypocreales and Microascales) and six families (Bionectriaceae, Halosphaeriaceae, Microascaceae, Nectriaceae, Sarocladiaceae and Stachybotryaceae). Ten new species are introduced and 13 new habitats and geographic records are reported. Mariannaea superimposita, Stachybotrys chartarum and S. chlorohalonatus are recollected from freshwater habitats in China. Based on phylogenetic analysis of combined LSU, ITS, SSU, rpb2 and tef1-α sequences data, Emericellopsis is transferred to Hypocreales genera incertae sedis; Pseudoacremonium is transferred to Bionectriaceae; Sedecimiella is placed in Nectriaceae; Nautosphaeria and Tubakiella are excluded from Halosphaeriaceae and placed in Microascales genera incertae sedis; and Faurelina is excluded from Hypocreomycetidae. Varicosporella is placed under Atractium as a synonym of Atractium. In addition, phylogenetic analysis and divergence time estimates showed that Ascocodina, Campylospora, Cornuvesica and Xenodactylariaceae form distinct lineages in Hypocreomycetidae and they evolved in the family/order time frame. Hence, a new order (Xenodactylariales) and three new families (Ascocodinaceae, Campylosporaceae and Cornuvesicaceae) are introduced based on phylogenetic analysis, divergence time estimations and morphological characters. Ancestral character state analysis is performed for different habitats of Hypocreomycetidae including freshwater, marine and terrestrial taxa. The result indicates that marine and freshwater fungi evolved independently from terrestrial ancestors. The results further support those early diverging clades of this subclass, mostly comprising terrestrial taxa and freshwater and marine taxa have been secondarily derived, while the crown clade (Nectriaceae) is represented in all three habitats. The evolution of various morphological adaptations towards their habitual changes are also discussed.
... With molecular DNA data, Glomerellaceae was validated by Zhang et al. (2006) as incertae sedis in Hypocreomycetidae. Subsequently, Glomerellales was phylogenetically delimited and validated to include three families, Glomerellaceae, Australiascaceae, and Reticulascaceae (Réblová et al. 2011a). Maharachchikumbura et al. (2015) and Tibpromma et al. (2018) added Plectosphaerellaceae and Malaysiascaceae to the order. ...
... Notes: Australiascaceae is a monotypic family with the holomorphic genus Monilochaetes as the type (Réblová et al. 2011a). Sivanesan and Alcorn (2002) erected Australiasca with type species A. queenslandica which was linked to the asexual morph Dischloridium camelliae experimentally. ...
... Australiasca queenslandica is similar to members of Chaetosphaeriaceae by the traits of ascomata, asci, ascospores and phialidic asexual morphs, while its gemination type resembles Lasiosphaeriaceae (Sivanesan and Alcorn 2002). Based on a phylogenetic study, Australiasca was confirmed unrelated to Chaetosphaeriaceae and Lasiosphaeriaceae but congeneric with the asexual genus Monilochaetes (Réblová et al. 2011a). Thus, Dischloridium (HKAS 112573, holotype) a Colony on wood. ...
Freshwater fungi comprises a highly diverse group of organisms occurring in freshwater habitats throughout the world. During a survey of freshwater fungi on submerged wood in streams and lakes, a wide range of sexual and asexual species were collected mainly from karst regions in China and Thailand. Phylogenetic inferences using partial gene regions of LSU, ITS, SSU, TEF1α, and RPB2 sequences revealed that most of these fungi belonged to Dothideomycetes and Sordariomycetes and a few were related to Eurotiomycetes. Based on the morphology and multi-gene phylogeny, we introduce four new genera, viz. Aquabispora, Neocirrenalia, Ocellisimilis and Uvarisporella, and 47 new species, viz. Acrodictys chishuiensis, A. effusa, A. pyriformis, Actinocladium aquaticum, Annulatascus tratensis, Aquabispora setosa, Aqualignicola setosa, Aquimassariosphaeria vermiformis, Ceratosphaeria flava, Chaetosphaeria polygonalis, Conlarium muriforme, Digitodesmium chishuiense, Ellisembia aquirostrata, Fuscosporella atrobrunnea, Halobyssothecium aquifusiforme, H. caohaiense, Hongkongmyces aquisetosus, Kirschsteiniothelia dushanensis, Monilochaetes alsophilae, Mycoenterolobium macrosporum, Myrmecridium splendidum, Neohelicascus griseoflavus, Neohelicomyces denticulatus, Neohelicosporium fluviatile, Neokalmusia aquibrunnea, Neomassariosphaeria aquimucosa, Neomyrmecridium naviculare, Neospadicoides biseptata, Ocellisimilis clavata, Ophioceras thailandense, Paragaeumannomyces aquaticus, Phialoturbella aquilunata, Pleurohelicosporium hyalinum, Pseudodactylaria denticulata, P. longidenticulata, P. uniseptata, Pseudohalonectria aurantiaca, Rhamphoriopsis aquimicrospora, Setoseptoria bambusae, Shrungabeeja fluviatilis, Sporidesmium tratense, S. versicolor, Sporoschisma atroviride, Stanjehughesia aquatica, Thysanorea amniculi, Uvarisporella aquatica and Xylolentia aseptata, with an illustrated account, discussion of their taxonomic placement and comparison with morphological similar taxa. Seven new combinations are introduced, viz. Aquabispora grandispora (≡ Boerlagiomyces grandisporus), A. websteri (≡ Boerlagiomyces websteri), Ceratosphaeria suthepensis (≡ Pseudohalonectria suthepensis), Gamsomyces aquaticus (≡ Pseudobactrodesmium aquaticum), G. malabaricus (≡ Gangliostilbe malabarica), Neocirrenalia nigrospora (≡ Cirrenalia nigrospora), and Rhamphoriopsis glauca (≡ Chloridium glaucum). Ten new geographical records are reported in China and Thailand and nine species are first reported from freshwater habitats. Reference specimens are provided for Diplocladiella scalaroides and Neocirrenalia nigrospora (≡ Cirrenalia nigrospora). Systematic placement of the previously introduced genera Actinocladium, Aqualignicola, and Diplocladiella is first elucidated based on the reference specimens and new collections.

Ferns are one of the most significant plant groupings that comprise a substantial proportion of the plant flora due to the fact of their great diversity, especially in tropical areas. The biodiversity of fungi associated with ferns and fern-like hosts has also received little attention in studies. Plant samples were collected from diseased and dead plants of ten fern or fern-like species from Chiang Rai in northern Thailand. Forty-one isolates were selected from the obtained isolates for molecular and morphological analysis, with a focus on pathogenic fungal genera and consideration of the diversity in host and geographical location. Twenty-six species belonging to seven genera (Colletotrichum, Curvularia, Diaporthe, Fusarium, Lasiodiplodia, Neopestalotiopsis, and Pestalotiopsis) in six families were identified. Thirty new hosts, eight new geographical hosts, and one new species, Colletotrichum polypodialium, are described. Nepestalotiopsis phangngaensis, N. pandancola, Diaporthe tectonendophytica, D. chiangraiensis, and D. delonicis were isolated for the first time from leaf spots. Additionally, new reservoirs and geographical locations for species previously isolated from leaf spots or whose pathogenicity was established were found. However, more studies are necessary to prove the pathogenicity of the fungi isolated from the leaf spots and to identify the fungi associated with other species of ferns.
... Notes: Réblová et al. (2011) reduced Cylindrotrichum hennebertii (CBS 570.76) to synonymy under Reticulascus tulasneorum (asexual morph C. oligospermum) (ex-type strain CBS 101319). Cylindrotrichum hennebertii was described as having conidia that are variable in size, 0-3-septate, 7-13 × 2-3 µm, and lacking sterile setae in vivo (Gams & Holubová-Jechová 1976). ...

Resistance to the antibiotic Cycloheximide has been reported for a number of fungal taxa. In particular, some yeasts are known to be highly resistant to this antibiotic. Early research showed that this resulted from a transition mutation in one of the 60S ribosomal protein genes. In addition to the yeasts, most genera and species in the Ophiostomatales are highly resistant to this antibiotic, which is widely used to selectively isolate these fungi. Whole-genome sequences are now available for numerous members of the Ophiostomatales providing an opportunity to determine whether the mechanism of resistance in these fungi is the same as that reported for yeast genera such as Kluyveromyces. We examined all the available genomes for the Ophiostomatales and discovered that a transition mutation in the gene coding for ribosomal protein eL42, which results in the substitution of the amino acid Proline to Glutamine, likely confers resistance to this antibiotic. This change across all genera in the Ophiostomatales suggests that the mutation arose early in the evolution of these fungi.
