   Fungalpedia – Note 1823, Anthostomella   Anthostomella. Sacc. Citation when using this data: Hyde KD et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Xylariaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi   Notes – Anthostomella is characterized by immersed, dark, clypeate ascomata with periphysate ostiolar canals, 8-spored, cylindrical, unitunicate asci and mostly dark, unicellular ascospores, sometimes with dwarf cells or appendages at the ends (Daranagama et al. 2015). Daranagama et al. (2015, 2016) described the polyphyletic nature of the genus and emphasized the need for recollection and providing molecular data. Voglmayr et al. (2018) re-evaluated the genus with suggestions to provide a new family for Anthostomella with the availability of sequence data of the type species. In this study, Anthostomella does not appear to be phylogenetically related to Xylariaceae. Daranagama et al. (2018) re-examined several herbarium specimens and tentatively synonymized Appendixia with [...]

Fungalpedia – Note 2154, Aaosphaeria   Aaosphaeria. Aptroot. Citation when using this data: Hongsanan S et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Dacampiaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi   Notes – A detailed description can be found in Van der Aa (1989, as Didymosphaeria). The genus was referred to the Dothideales by Aptroot (1995) who also suggested that it could be close to Polycoccum in Dacampiaceae despite different asexual stages. The genus was tentatively accepted in Dacampiaceae by Lumbsch & Hundorf (2007) and Hyde et al. (2013). The type species was originally collected from soil of corn field (under Zea mays) in Colombia, with a culture isolated (Van der Aa 1989). It was also reported from different plant hosts Coffea, Mangifera, Solidago and Zigyphus (Aptroot 1995). According to the original description, A. arxii has a Microsphaeropsis asexual morph, but the type species [...]

Fungalpedia – Note 270,  Abieticola   Abieticola Hyang B. Lee. Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016. 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 2592, Abrothallaceae   Abrothallaceae Pérez-Ort. & Suija. Citation when using this data: Meng QF et al. – Fungalpedia. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Abrothallales, Dothideomycetes orders incertae sedis, Pezizomycotina, Ascomycota, Fungi Abrothallaceae and Abrothallales were established by Pérez-Ortega Et al. (2014) to accommodate Abrothallus having sexual and asexual morph. The family is distinguished by apothecioid ascomata protruding through the host cortex, sessile or partly immersed, spherical to flattened, often with a greenish or yellowish pruina. Its hamathecium is composed of thick-walled, unequally dichotomously branched and anastomosed, septate interascal filaments. Asci are bitunicate, functionally fissitunicate, broadly to narrowly clavate, I–, comprising of four to eight ascospores. Ascospores are initially hyaline, later brown, often verruculose, one-, two- or three septate, breaked into part-spores from septa in some species, asymmetric in shape. Its anamorph is characterized by phynidial, [...]

Fungalpedia – Note 1534, Abrothallales   Abrothallales. Pérez-Ort. & Suija. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Incertae sedis, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi   Abrothallales was established by Pérez-Ortega and Suija (in Pérez-Ortega et al. 2014) based on its monophyletic placement and morphological distinctness within the class Dothideomycetes. Diederich et al. (in Hyde et al. 2013) had introduced Lichenoconiales, which Liu et al. (2017) recovered as a sister clade of Abrothallales, raising the question of whether both orders should be maintained. Diederich et al. (2018) synonymized Lichenoconiales with Abrothallales and tentatively Lichenoconiaceae with Abrothallaceae. Pérez-Ortega and Suija agreed with Diederich et al. (2018) to use the name Abrothallales since Abrothallus is the most outstanding, easily recognizable and better-known genus of the group. Lichenoconiaceae is the older name, therefore, we retain Lichenoconiaceae over Abrothallaceae. Abrothallales contains species which are lichenicolous, parasymbiontic or parasitic on macrolichens from a single family Abrothallaceae (Pérez-Ortega et al. 2014; Wijayawardene et al 2017).   Type family: Abrothallaceae Pérez-Ort. & Suija, in [...]

Fungalpedia – Note 1550, Abrothallus   Abrothallus. De Not. = Vouauxiomyces Dyko & D. Hawksw., Lichenologist 11(1): 57 (1979). Index Fungorum, Facesoffungi, MycoBank, GenBank – 42 morphological species (Species Fungorum 2020), 20 species with molecular data. Classification: Abrothallaceae, Abrothallales, Incertae sedis, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi   Notes: De Notaris described Abrothallus as a lichenized taxon (De Notaris 1846, 1849). Tulasne (1852) and Lindsay (1857) unequivocally established its lichenicolous habit. Suija et al. (2018) fixed the nomenclatural problems concerning the exact date of publication, confirming A. bertianus as the type species. They also reviewed the material described by Giuseppe De Notaris, Søren Christian Sommerfelt, and Ignaz Kotte lectotypifying Abrothallus species described by these authors (Suija et al. 2018). These authors also introduced the combination A. santessonii (≡ Vouauxiomyces santessonii), providing an updated description for this taxon. Pérez-Ortega et al. (2011) established the connection between the sexual and asexual morphs. The number [...]

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 [...]
