(2014) introduced Pseudoacremonium to accommodate Pseudoacremonium sacchari as a monotypic species based on morphological and molecular studies (ITS and LSU). Only asexual morph has been reported from this genus and are characterized by erect conidiophores with subcylindrical, rarely branched, 1–3-septate, smooth-walled, and brown with age, verruculose and warty; elongate-ampulliform or navicular conidiogenous cells with terminal, integrated, tapering towards apex, with prominent periclinal thickening and inconspicuous collarette, hyaline to brown, and verruculose to warty; unbranched chain conidia, ellipsoid, aseptate, thin-walled, hyaline to brown, verruculose, guttulate, with scarring at each end, appearing flaky when mounted in [...]

Fungalpedia - Note 36 Pseudoallosoma   Pseudoallosoma F.B. Rocha, J.L. Bezerra & R.W. Barreto Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep) Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Rocha et al. (2010) introduced Pseudoallosoma as a fungus associated with Coussapoa floccosae in Brazil's tropical seasonal semideciduous montane forest. Pseudoallosoma nervisequens F.B. Rocha & R.W. Barreto is the only species of the genus that share similarity with Allosoma and Dictyonella in Saccardiaceae, however, some distinct features verified its placement in Myriangiaceae (Myriangiales). The proliferation of the colony of this fungus on the leaves gives them a mosaic appearance. The species produced superficial pseudothecia ascomata, which are solitary, globose to subglobose, and encircled with setae. Asci are bitunicate, subglobose, ellipsoid to obovoid, few per ascoma, and contain [...]

Fungalpedia – Note 121 Pseudoalternaria   Pseudoalternaria D.P. Lawr., Gannibal, Dugan & B.M. Pryor Citation when using this entry: Tibpromma et al., in prep – Fungalpedia, new genera and higher taxa in 2014. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. Pseudoalternaria was described with the type species Pseudoalternaria arrhenatheria, and Alternaria rosae was transferred to Pseudoalternaria based on morphological and molecular data (single and combined ITS/gpd/Plasma membrane ATPase) (Lawrence et al. 2014). The morphology of Pseudoalternaria is similar to Alternaria, but phylogenetic analysis, showed that Pseudoalternaria formed an independent lineage basal to Alternaria. Lawrence et al. (2016) transferred Pseudoalternaria to a new section of Alternaria (sect. Pseudoalternaria). However, Pseudoalternaria is invalid (Art. F.5.1, Shenzhen). Type species: Pseudoalternaria arrhenatheri D.P. Lawr., Gannibal, F.M. Dugan & B.M. Pryor Other described species: Pseudoalternaria rosae (E.G. Simmons & C.F. Hill) D.P. Lawr., Gannibal, Dugan [...]

Index Fungorum, Facesoffungi, MycoBank, GenBank, Figs. 1 & 2 Classification: Incertae sedis, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Daranagama et al. (2016) established Pseudoanthostomella in Xylariaceae with P. pini-nigrae as the type. The genus was transferred to Xylariales incertae sedis by Samarakoon et al. (2022) based on the combined ITS-LSU-rpb2-tub2-tef1 phylogenies. The sexual morph of Pseudoanthostomella is characterized by immersion in semi-immersed ascomata that developed beneath the clypeus. Ascomata appear as blackened, raised, and conical dome-shaped areas. They are coriaceous or carbonaceous, solitary, rarely aggregated, mostly subglobose with a reduced clypeus, and usually lack a periphysate ostiolar canal. Clypeus is black, thick walled, short, and comprises dark fungal [...]

Fungalpedia – Note 283, Pseudoascotaiwania   Pseudoascotaiwania Jing Yang, Bhat & K.D. Hyde Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fuscosporellaceae, Fuscosporellales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Yang et al. (2016) introduced the monotypic genus Pseudoascotaiwania based on a combined LSU, SSU, and rpb2 phylogeny to accommodate Ascotaiwania persoonii, which clusters distant from the type species of Ascotaiwania (Fallah et al. 1999). Pseudoascotaiwania persoonii is saprobic on twigs in freshwater habitats (Fallah et al. 1999; Yang et al. 2016). The genus is characterized by scattered, immersed, black, urniform, rostrate, and membranous ascomata. Simple septate periphyses lining the beaked ostiolar canal. The peridium is several layers thick and brown with an angularis texture. Paraphyses are simple or branched. [...]

Fungalpedia – Note 284, Pseudofusicolla   Pseudofusicolla D. Triest  Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Nectriaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi             Pseudofusicolla was introduced after re-examining herbarium material of four strains, which provisionally retained as “Fusarium”, and based on multigene phylogeny (Triest et al. 2016). The genus was typified as Pseudofusicolla belgica. Pseudofusicolla belgica was isolated from recycled water from air conditioners and spray humidifiers (Triest et al. 2016). The asexual morph of Pseudofusicolla on SNA is characterized by branched conidiogenous cells or conidiogenous cells scattered along branched hyphae. Conidiogenesis began with phialides after a few days. Microconidia are strongly falcate, aseptate or 1-septate, while macroconidia are strongly falcate, smooth-walled, aseptate to three-septate.

Fungalpedia - Note 246, Pseudomalbranchea   Pseudomalbranchea Rodr.-Andr., Cano & Stchigel  Citation when using this entry: Thakshila et al. 2024 (in prep) – Fungalpedia, Onygenales, Eurotiales, and Verrucariales.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1. Classification: Incertae sedis, Onygenales, Eurotiomycetidae, Eurotiomycetes, Fungi The monotypic genus, Pseudomalbranchea was introduced by Rodríguez-Andrade (2021). This genus was typified by P. gemmata, which was isolated from human bronchial washing specimens in Florida, USA. Only an asexual state has been reported. Pseudomalbranchea has smooth, thin-walled, hyaline, and sparsely septate hyphae. Enteroarthric conidia are released from the fertile hyphae by rhexolysis and are solitary or in short chains (up to 7), one-celled, hyaline, smooth, thick-walled, and cylindrical to globose (Rodríguez-Andrade, 2021). Based on phylogenetic analyses of the ITS and LSU sequences, P. gemmate is closely related to Uncinocarpus reesii and Amauroascus volatilis-patellis. However, P. gemmate is morphologically distinct from U. reesii [...]

Fungalpedia - Note 25 Pseudomicrothecium   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Pseudomicrothecium Y. Marín, Stchigel, Guarro & Cano Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1             Pseudomicrothecium was introduced as a novel genus with the type species P. subterraneum (L. Fan, C.L. Hou, P.F. Cannon & Y. Li) Y. Marín, Stchigel, Guarro & Cano by  Marín-Felix et al. (2018). Pseudomicrothecium subterraneum was found as a mycoparasite on the tissue of Tuberaceae (Tuber indicum and T. huidongense) in China (Fan et al. 2012) and it is the only species listed in Index Fungorum (2022). Pseudomicrothecium is closely related to Microthecium and Scopinella (Marín-Felix et al. 2018). However, Microthecium has more than two ascospores within its asci and Scopinella has long necked ostiolate ascomata and cuboid to ellipsoidal ascospores with two prominent longitudinal germ slits (Marín-Felix et al. 2018). Pseudomicrothecium is characterized by astromatic ascomata that are pale [...]

Fungalpedia - Note 414, Pseudophialophora   Pseudophialophora J. Luo & N. Zhang Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomycota.

Pseudophialophora was introduced by Luo et al. (2014) as a monotypic genus within Magnaporthaceae and typified with Pseudophialophora eragrostidis based on morphology and multigene phylogeny of SSU, ITS, LSU, MCM7, RPB1 and TEF1-α. Luo et al. (2014) introduced three new species isolated from the roots of Poaceae plants in the USA. Six new species were introduced into this genus, which were isolated from the roots of Poaceae plants in Brazil and the USA (Luo et al. 2015, Crous et al. 2017). Currently, nine species of Pseudophialophora have been isolated from grass rot (Luo et al. 2014, 2015, Crous et al. 2017, Hyde et [...]

Fungalpedia - Note 260, Pseudopithomyces   Pseudopithomyces Ariyaw. & K.D. Hyde. Citation when using this entry: Aumentado et al. 2024 (in prep) – Fungalpedia, plant pathogens.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1.  Classification: Didymosphaeriaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi Pseudopithomyces was established by Ariyawansa et al. (2015) in Didymosphaeriaceae, with Pseudopithomyces chartarum as its type species. This classification system was introduced to encompass various strains previously classified as Pithomyces chartarum (Berk. & M.A. Curtis) M.B. Ellis, P. maydicus (Sacc.) M.B. Ellis, P. sacchari (Speg.) M.B. Ellis and other related Pithomyces strains grouped within the family Didymosphaeriaceae (Ariyawansa et al. 2015). Pseudopithomyces resembles Pithomyces in having echinulate or fusiform, verruculose dark conidia, and the production of brown to black colonies on the host. However, Pithomyces distinguishes itself by producing lighter obovate to oblong verruculose to spinulose conidia, [...]
