Fungalpedia – Note 2115, Acroconidiella   Acroconidiella J.C. Lindq. & Alippi Citation when using this data: Hongsanan S et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank. Classification: Cladosporiaceae, Cladosporiales, Dothideomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi Acroconidiella is characterized by macronematous, mononematous, mostly unbranched conidiophores, polytretic, terminal conidiogenous cells, and ellipsoidal, septate conidia (Ellis 1971,1976, Prasher & Verma 2015). Prasher & Verma (2015) provided morphological comparison of Acroconidiella species. Fresh collections are required to resolve its phylogenetic placement, since no molecular data are available for this genus. Type species: Acroconidiella tropaeoli (T.E.T. Bond) J.C.

 Fungalpedia – Note 1816, Acrocordiella   Acrocordiella. O.E. Erikss. Citation when using this data: Hyde KD et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Classification: Requienellaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Notes – Acrocordiella is characterised by solitary or small groups of immersed ascomata with white or black margins, a peridium comprising brown to hyaline, thick-walled cells of textura angularis and 3-distoseptate ascospores with rhomboid lumina. This genus has been considered as a synonym of Requienella (Boise 1986). Wijayawardene et al. (2018a) listed Acrocordiella in Pyrenulaceae. However, Jaklitsch et al. (2016b) and Maharachchikumbura et al. (2016b) confirmed Acrocordiella and Requienella as distinct genera of Requienellaceae in Xylariales (Sordariomycetes) based on phylogenetic analyses.   Type species: Acrocordiella occulta (Romell) O.E.

Fungalpedia – Note 1061, Acrocordiopsis   Acrocordiopsis. Borse & K.D. Hyde. Citation when using this data: Dayarathne MC et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Classification: Melanommataceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi  Acrocordiopsis patilii was phylogenetically first treated by Suetrong et al. (2009) who demonstrated that A. patilii grouped as a residual paraphyletic assemblage within the class Dothideomycetes and could not be assigned to any of the families in this class. Subsequently, this was supported by Jones & Pang (2012). Hyde et al. (2013) assigned Acrocordiopsis to Salsugineaceae based on sequence data of Suetrong et al. (2009). Ariyawansa et al. (2015b) accommodated Acrocordiopsis in the family Caryosporaceae along with Caryospora, while, Wijayawardene et al. (2018) listed A. patilii in Salsugineaceae following Hyde et al. (2013). There are two accepted [...]

Fungalpedia – Note 890, Acrodictyaceae   Acrodictyaceae. J.W. Xia & X.G. Zhang. Citation when using this data: Dong W et al. 2021 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Diaporthales, Diaporthomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi Acrodictyaceae was introduced to accommodate a single genus Acrodictys characterized by acrogenous, obovoid to pyriform, muriform conidia (Xia et al. 2017). The phylogenetic position of Acrodictyaceae is unstable, as it clusters with Junewangiaceae, Papulosaceae or Sporidesmiaceae in different studies (Xia et al. 2017, Luo et al. 2019, Hyde et al. 2020). All these three families have annulatascaceae-like sexual morphs, e.g. Dictyosporella thailandensis in Junewangiaceae, Fluminicola aquatica in Papulosaceae, and Sporidesmium thailandense in Sporidesmiaceae (Zhang et al. 2017). However, no sexual morph is linked to Acrodictyaceae. Although the placement of Acrodictyaceae is unstable, it clusters with Diaporthomycetidae families in all studies (Luo et al. 2019, Hyde et al. 2020, this study).

Fungalpedia – Note 891, Acrodictys   Acrodictys. M.B. Ellis. Citation when using this data: Dong W et al. 2021 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank., Fig 1 Classification: Acrodictyaceae, Diaporthales, Diaporthomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Acrodictys was introduced to accommodate species having conidiophores often with successive terminal proliferations, and variable-shaped, dictyoseptate, pale brown to dark blackish brown conidia (Ellis 1961). The type species A. bambusicola was initially collected in Venezuela (Ellis 1961), later collected and sequenced from China (Xia et al. 2017). Acrodictys is confused with Junewangia as both genera have long conidiophores with percurrent proliferations, and dictyoseptate conidia often with a protruding base (Xia et al. 2017). However, phylogenetic analysis places them in Acrodictyaceae and Junewangiaceae, respectively. The latest treatment was carried out by Luo et al. (2019), who introduced a new species A. fluminicola and a new combination [...]

Fungalpedia – Note 1161, Acrophialophora   Acrophialophora Edward Citation when using this data: Hyde KD et al. 2020 (in prep.) – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank. Classification: Chaetomiaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Acrophialophora was reintroduced by Samson & Mahmood (1970) as a thermotolerant genus with A. fusispora, A. levis and A. nainiana. Based on combined analysis of ITS, SSU and tub2 sequence data, Zhang et al. (2015a) showed that Acrophialophora is a monophyletic genus in Chaetomiaceae and they synonymized Taifanglania under Acrophialophora. The genus is characterised by conidiophores that are absent or unbranched or sparingly branched conidiogenous cells that are monophialidic or polyphialidic with two necks, flask-shaped or in whorls in verticillate species. Conidia are unicellular, subglobose, elliptical to fusiform, echinulate, with spiral bands or smooth, in basipetal chains or slimy heads and with schizolytic secession (Zhang et [...]

Fungalpedia – Note 2184, Acrospermales   Acrospermales. Minter, Peredo & A.T. Watson. Citation when using this data: Afshari N et al. 2025 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Incertae sedis, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi   Acrospermales was established by Minter et al. (2007) as an incertae sedis taxon. It was placed in an independent lineage that was closely related both Dothideomycetes and Arthoniomycetes (Stenroos et al. 2010). Later, Pang et al. (2013) assigned Acrospermales to Dothideomycetes based on phylogenetic analysis of partial SSU, LSU, and tef1-α sequences. Acrospermales represents one of the least studied orders of Dothideomycetes and includes epiphytic, saprotrophic, fungicolous, lichenicolous, and bryophilous species. The ordinal placement of Acrospermaceae has been disputed for a long time (Hudson et al. 2019, Darmostuk & Flakus 2024). In this study, we introduced a new family Novolignincolaceae to [...]

Fungalpedia – Note 1817, Acrostalagmus   Acrostalagmus. Corda. Citation when using this data: Hyde KD et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank Classification: Hypocreaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi    Notes – Acrostalagmus cinnabarinus turned out to be identical to Verticillium luteoalbum (≡ Sporotrichum luteoalbum), introduced by Link (1809). Thus, the new combination Acrostalagmus luteoalbus was proposed as the type species of Acrostalagmus (Zare et al. 2004). Acrostalagmus has mononematous or synnematous conidiophores, enteroblastic, monophialidic conidiogenous cells, and hyaline or bright orange to reddish, oval, ellipsoidal to oblong-ellipsoidal conidia, held together by slime (Corda 1838, Giraldo & Crous 2019). Based on morphology, substrate relationships, and phylogenetic analyses, Zare et al. (2004) demonstrated the asexual-sexual connection was erroneous for Acrostalagmus. Its sexual morph is undetermined.   Type species: Acrostalagmus luteoalbus (Link) Zare, W. Gams & Schroers, Mycol. Res. 108(5): 581 (2004). Other accepted species: [...]

Fungalpedia – Note 2249, Actidium   Actidium Fr. Citation when using this data: Hongsanan S et al. 2020 – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank. Classification: Mytilinidiaceae, Mytilinidiales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi This genus was established by Fries (1823) to accommodate A. hysterioides, a stellate mytilinidioid fungus found on Pinus and Picea in Europe, with two-celled, symmetric ascospores, light olive to reddish brown, later noted to be faintly longitudinally striate (Barr 1990a). Fries (1823) noted its similarity with Glonium. Zogg (1962) and Barr (1990b) recognised four species, A. hysterioides, A. baccarinii, both from Europe, A. pulchra, from China, and A. nitidum. Due to similarities in ascospore morphology, Actidium may have affinities with other didymospored hysteriaceous genera (e.g. Actidiographium, Glonium and Psiloglonium), although molecular data are lacking. Type species: Actidium hysterioides Fr., Observ. mycol. (Havniae) 2: 353 (1818). Other accepted [...]
