Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Xylariaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Lee et al. (2016) introduced the monotypic hyphomycetous genus Abieticola to accommodate A. koreana, based on the phylogeny of ITS, LSU, rpb2, and tub2 markers. Abieticola koreana is an endophytic species isolated from inner bark of Abies holophylla (Lee et al. 2016). Abieticola is distinguished by stromata that typically form on PDA, resembling tiny clubs with white heads and blackish brown exudates oozing out along the lower stalk. Synnemata are generally erect but curving with age, with knotted hyphae of variable thickness, brown to yellow in color, and functioning as conidiophores. One or two (occasionally [...]

Fungalpedia - Note 47 Abstoma   Abstoma G. Cunn Citation if using this entry: Bera et al. (2023) Basidiomycota. Mycosphere (in prep) Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 The genus Abstoma was established by Cunningham (1926) under the family Lycoperdaceae incorporating the characters such as basidiomes without any determined stoma, a wavy capillitium, a peridium rupturing irregularly, and basidiospores with reticulate ornamentation. Later, both the smooth-surfaced and ornamented basidiospores were incorporated under Abstoma (Wright & Suárez 1990). Other characteristics of this genus that make it quite unique are its globose-shaped, deeply coloured basidiospores with conspicuous to obsolete pedicels, short and smooth threads of capillitium, and an exoperidium often intermixed with sand particles (Cunningham 1926, Wright & Suárez 1990, Gube & Dörfelt 2011). Abstoma represents the gasteroid macrofungi and is placed under the [...]

Fungalpedia - Note 39 Abundisporus   Abundisporus Ryvarden Index Fungorum, MycoBank, GenBank, Fig. 1 The genus Abundisporus Ryvarden typified by A. fuscopurpureus (Pers.) Ryvarden was established in 1998 while studying the diversity of the poroid mushrooms of tropical Africa (Ryvarden 1998). The basidiocarps are mostly of pileate to resupinate habit (Ryvarden 1998, Zhao et al. 2015). The context is usually of a range of colours from umber brown to greyish to purplish brown (Ryvarden 1998, Zhao et al. 2015). The hyphal system is dimitic with pale brown to yellow skeletal hyphae (Ryvarden 1998, Zhao et al. 2015). The basidiospores of this genus are generally pale yellowish, slightly thick-walled, ellipsoid, and non-dextrinoid (Ryvarden 1998, Zhao et al. 2015). The tissues of Abundisporus turns brownish on reaction with Potassium hydroxide (Zhao et al. 2015). Taxonomic studies revealed that [...]

Fungalpedia - Note 63 Acanthofungus   Acanthofungus Sheng H. Wu, Boidin & C.Y. Chien Citation if using this entry: Bera et al. (2023) Basidiomycota. Mycosphere (in prep)   Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 The whitish, resupinate, pulvinate, and deeply cracked basidiomata of this wood-decaying basidiomycete is reminiscent of Xylobolus frustulatus (Pers.) P. Karst (Wu et al. 2000). After being documented first from an endemic gymnosperm tree (Calocedrus formosna) in Taiwan, monosporous and polysporous cultures were prepared (Wu et al. 2000). Based on the cultural and morphological characteristics, Acanthofungus was introduced, and typified by A. rimosus Sheng H. Wu, Boidin & C.Y. Chien under the family Stereaceae (Wu et al. 2000). The appearance of the basidiomata is composed of many orbicular patches and pieces (Wu et al. 2000). The hymenium shows distinct thickening with a [...]

Fungalpedia – Note 112 Achrochaeta   Achrochaeta Réblová & Hern. -Restr. Citation when using this entry: Silva et al., in prep – Fungalpedia, Sordariomycetidae. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Achrochaeta was introduced by Réblová et al. (2021) as a monotypic genus to accommodate Achrochaeta talbotii (S. Hughes, W.B. Kendr. & Shoemaker). Réblová & Hern.-Restr., isolated from decaying wood collected from New Zealand (Réblová et al. 2021). The phylogenetic analysis using ITS and 28S sequences revealed that their isolate clustered with Chaetosphaeria talbotii, representing a novel lineage in the Chaetosphaeriaceae separating it from Dictyochaeta. Therefore, C. talbotii was synonymized under a new genus Achrochaeta (Réblová et al. 2021). Morphologically, it is characterized by its sexual and asexual morphs. The sexual morph is a perithecial, astromatic ascomata with a carbonaceous ascomatal wall and periphysate ostioles. Paraphyses are hyaline and septate, [...]

Fungalpedia – Note 289, Achroiostachys   Achroiostachys L. Lombard & Crou Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Stachybotryaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Lombard et al. (2016) erected the hyphomycetous genus Achroiostachys to accommodate a group of stachybotrys-like taxa that distantly related to Stachybotrys in the analysis of cmdA, ITS, rpb2, tef1 and tub2 sequences. Achroiostachys is characterized by macronematous, mononematous conidiophores that occur solitary or in clusters. Conidiophores are erect, 1–3-septate, unbranched or rarely branched, hyaline and thin-walled. The majority of them have smooth walls, though occasionally the base becomes slightly verrucose. Phialidic conidiogenous cells are occurring in apical cluster of 2–6 per conidiophore. Conidiogenous cells are elongate ampulliform to ventricose to [...]

Fungalpedia - Note 7 Alascospora   Alascospora Raja, Violi & Shearer   Citation if using this entry: Fahalli et al. (2023) New genera in 2010-2011. Mycosphere (in press) Index Fungorum Identifier 514031, Facesoffungi, MycoBank, GenBank, Freshwaterfungi.org, Fig 1. Based on unique morphological characteristics Alascospora, a freshwater ascomycete, was introduced in Pleosporales incertae sedis (Pleosporomycetidae, Dothideomycetes), by Raja et al. (2010). The sole species of the genus Alascospora evergladensis was isolated from submerged dead petioles of Nymphaea odorata, during an investigation of aquatic fungi along a phosphorus gradient in the Florida Everglades. The fungus produces light brown, translucent, and membranous ostiolate perithecia. Dark and amorphous material is irregularly deposited on the peridium, especially around the ostiole. Asci are globose, fissitunicate, and thick-walled. Ascospores are 1-septate and hyaline when young, and enclosed by a hyaline gelatinous sheath that resembles two wings (Raja [...]

Fungalpedia - Note 143 Albatrellus   Albatrellus Gray  Citation if using this entry: Bera et al. (in prep) – Fungalpedia, Basidiomycota 1. Mycosphere. Index Fungorum, MycoBank, Facesoffungi, GenBank, Fig. 1 Albatrellaceae, Russulales, Agaricomycetes, Basidiomycota, Fungi Albatrellus was described by S.F. Gray (1821) based on Albatrellus albidus Gray in his work “A Natural Arrangement of British Plants". The poroid hymenophore of Albatrellus initially placed the genus under the order Polyporales (Kirk et al. 2001). However, as the study progressed combining the morphology and the molecular data, Albatrellus was revealed to be polyphyletic (Bruns et al. 1998, Zheng & Liu 2008). The primary phylogenetic analyses based on the mitochondrial large subunit rRNA gene placed some species of Albatrellus closely related to the members of the family Russulaceae (Bruns et al. 1998). Based on further studies dealing with other [...]
