Fungalpedia – Note 1815, Acaulium   Acaulium. Sopp. Citation when using this data: Hyde KD et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Microascaceae, Microascales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi   Notes – The asexual morph is hyphomycetous and has been treated as a synonym of Scopulariopsis by Seifert et al. (2011). Species occur in terrestrial habitats worldwide and are characterized by annellidic conidiogenesis with mycelium forming hyphal fascicles and guttulate conidia. Taxonomic revisions were carried out by Kirk et al. (2013). Sandoval-Denis et al. (2016a) accepted, Acaulium, in Microascaceae by segregating it from Microascus and Scopulariopsis based on molecular phylogenetic study. The placement of the genus was also accepted in Maharachchikumbura et al. (2015, 2016b) and Wijayawardene et al. (2017a, 2018a).   Type species: Acaulium albonigrescens Sopp, Skr. VidenskSelsk. Christiania, Kl. I, Math.-Natur.(no. 11): 70 (1912).

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 [...]

Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Clavicipitaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi  Notes – This genus contains bamboo specific endophytic pathogens (Oguchi 2001, Tanaka et al. 2003). The species produce multi-septate ascospores with no obvious part spores (Oguchi 2001). Neoclaviceps and Cepsiclava were combined under Aciculosporium based on phylogenetic and evolutionary analyses (Píchová et al. 2018). Type species: Aciculosporium take I. Miyake, Bot.

Fungalpedia – Note 389, Acidea   Acidea Hujslová & M. Kolařík Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Incertae sedis, Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi. Based on the phylogenies of LSU and SSU analyses and morphological studies, the genus Acidea was established in Leotiomycetes by Hujslova et al. (2014) to accommodate the type species A. extrema. Acidea is characterized by hyphomycetes morph, compact colonies with ruffled margins, wrinkled, centrally heaped to cerebriiform, funiculose or yeast-like, white to beige, mycelium sterile, sparsely branched, fully filled with a single line of granules, often fragmenting (Hujslova et al. 2014). No other species have been introduced to this genus, which remains monotypic.             Type species: Acidea extrema Hujslová & M. Kolařík Other accepted species: This genus is [...]

Fungalpedia - Note 442, Acidomelania   Acidomelania E. Walsh & N. Zhang  Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomata. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig.1  Classification: Incertae sedis, Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi. Based on molecular phylogenetic analyses and ecological and morphological characteristics, Walsh et al. (2014) introduced Acidomelania as a monotypic genus for Helotiales, a heterogeneous and the largest order in Leotiomycetes, which includes endophytes, plant pathogens, and saprobes. The type species of this genus is Acidomelania panicicola, which was isolated as an endophytic species from the roots of Panicoideae (Walsh et al. 2014). Acidomelania sporulated at room temperature within three weeks with simple or occasionally branched conidiophores with hyaline conidiogenous cells, straight; cylindrical collarettes; conidia aggregated in slimy heads, globose to subellipsoidal, aseptate, hyaline, smooth-walled, whereas chlamydospores [...]

Fungalpedia – Note 1244, Acidomyces   Acidomyces B.J. Baker, M.A. Lutz, S.C. Dawson, P.L. Bond & Banfield ex Selbmann, de Hoog & De Leo Citation when using this data: Hongsanan S et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank. Classification: Teratosphaeriaceae, Mycosphaerellales, Dothideomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi Baker et al. (2004) introduced Acidomyces but the name was invalid (Art. 35.1; Index Fungorum 2020). Hence, Selbmann et al. (2008) validated the genus. Hujslová et al. (2013) accepted the genus as in Teratosphaeriaceae but Quaedvlieg et al. (2014) did not include the genus in their phylogenetic analyses. See description and illustration in Selbmann et al. (2008), Hujslová et al. (2013). Type species: Acidomyces acidophilus (Sigler & J.W. Carmich.) Selbmann, de Hoog & De Leo, Stud. Mycol. 61: 17 (2008).  ≡ Scytalidium acidophilum Sigler & J.W.

Based on phylogenies of LSU analyses and morphological studies, Acidothrix was established in Amplistromataceae by Hujslova et al. (2014) to accommodate the type species Acidothrix acidophila. Acidothrix is characterized by hyphomycetes morph, sporulation abundant, on acidic medium compact, centrally forming funicules, white, powdery; acrodontium–like conidiophores, semimacronematous or macronematous; single conidia, globose, or ellipsoidal to lacrimose, with hilum (Hujslova et al. 2014).
