Fungalpedia - Note 3 Lucidascocarpa   Lucidascocarpa Ferrer, Raja & Shearer  Citation if using this entry: Noorabadi MT & Hyde KD (2023) New genera in 2008. Mycosphere (in press)  Index Fungorum Identifier 508169, Facesoffungi, MycoBank, GenBank, freshwater fungi.org, Fig 1  Ferrer & Shearer (2008) introduced Lucidascocarpa as a monotypic genus that was found as a saprobe on decorticated wood submerged in a river in Ecuador. This genus was placed in an uncertain position in Dothideomycetes, Ascomycota and is typified by Lucidascocarpa pulchella Ferrer, Raja & Shearer. Lucidascocarpa is characterized by rough-walled ascospores surrounded by a large gelatinous sheath. Asci are 8-spored, bitunicate, fissitunicate, clavate, pedicellate, with gelatinous material around the apex of the endoascus comprising eight overlapping, biseriate ascospores. Ascomata are white with the long necks, superficial or immersed, scattered or clustered, umbilical to subglobose, cylindrical, periphysate.     Fig 1. [...]

Fungalpedia - Note 485, Macgarvieomyces   Macgarvieomyces Klaubauf, Lebrun & Crous. Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Fungal pathogens. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Pyriculariaceae, Magnaporthales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi. Macgarvieomyces was named after the famous Scottish plant pathologist, Quentin D. MacGarvie (Klaubauf et al. 2014). The pathogenic genus Macgarvieomyces exhibits several distinguishing characteristics, including brown ellipsoidal chlamydospores arranged in chains. Conidiophores often exhibit medium brown coloration and are observed as individual structures. They possess a non-branching morphology, appearing as straight or slightly curved entities in the presence of the septa. Conidiogenous cells are typically located in the terminal position, but may occasionally be found in an intercalary position (Klaubauf et al. 2014). These cells have a medium brown coloration and commonly arrange themselves in [...]

 Fungalpedia – Note 317, Macronectria   Macronectria Salgado & P. Chaverri  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.             Salgado-Salazar et al. (2016) proposed Macronectria based on Thelonectria jungneri and four other taxa with cylindrocarpon-like asexual morphs. These taxa showed a distant phylogenetic relationship with species in Thelonectria s. str. in the analysis of eight concatenated loci (act, ITS, LSU, rpb1, rpb2, SSU, tef1, and tub2) (Salgado-Salazar et al. 2016). The sexual morph of Macronectria is characterized by subglobose to pyriform, sometimes elongated and fask-shaped, perithecial ascomata that are gregarious and superficial on an erumpent stroma. Ascomata do not collapse when dry, are (370–)400–520(600) μm in size [...]

  Fungalpedia – Note 329, Magnosporites (Fossil Fungi)   Magnosporites Rouse. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Amerosporae, Incertae sedis, Fungi Rouse (1962) described the monotypic fossil genus, Magnosporites, from the Burrard Formation (Late Cretaceous-Middle Eocene, (100–38 mya) sediments of Terminal Dock, the city of Vancouver, British Columbia, Canada. This genus includes spore-like bodies having circular to elliptical outline and a fairly thin wall (ca. 1.5 μm). The wall is bright yellow and is always folded and contorted. There is no apparent aperture and no ornamentation on the smooth surface. Size-range is 100–170 μm. According to Rouse (1962), these structures are associated with freshwater plants, as they are found only in freshwater deposits. Whether they are spores, [...]

Fungalpedia - Note 244, Malbranchea   Malbranchea Sacc. Citation when using this entry: Thakshila et al. 2024 (in prep) – Fungalpedia, Onygenales, Eurotiales, and Verrucariales.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Onygenaceae, Onygenales, Eurotiomycetidae, Eurotiomycetes, Fungi Malbranchea was introduced as a family by Saccardo (1882) which was isolated on wet-cardboard in Rouen, France. This genus is typified by Malbranchea pulchella, and naturally occurs as a saprophyte on decaying plant materials or as a parasitic organism in animals (Cooney & Emerson 1964). Only an asexual state has been reported. Benda & Corey (1994) and Cooney & Emerson (1964) reported three cases of sinonasal M. pulchella infections in humans. Malbranchea is characterized by branched hyphae with prominent swelling near the septations. Fertile hyphal tips progressively and regularly septate toward the base. Curved fertile branch tips consist of thick-walled arthroconidia and thin-walled isthmus. After breaking off the connecting isthmuses, the conidia [...]

Fungalpedia - Note 68 Marchandiopsis   Marchandiopsis Ghob.-Nejh. & Hallenb. (Current Name: Marchandiomyces Diederich & D. Hawksw., in Diederich)    Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep). Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Marchandiopsis was introduced by Ghobad-Nejhad et al. (2010) in Corticiaceae (Corticiales). They stated that Laeticorticium quercinum, the sexually reproducing fungus, and Marchandiomyces corallinus as an asexual fungus belonged to the same clade based on the Bayesian analysis of the nuclear LSU sequence data. They considered that these fungi belonged to the same genus, and because the ICBN (McNeill 2007) prohibits the inclusion of a sexual species in a genus that only contains asexual organisms, the new genus Marchandiopsis was suggested, and Marchandiopsis quercina was introduced as the type species. Hawksworth & Henrici (2015) changed the [...]

Fungalpedia – Note 547, Marchantiana   Marchantiana S.Y. Kondr., Kärnefelt, Elix, A. Thell & Hur Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomycota.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Teloschistaceae, Teloschistales, Lecanoromycetidae, Lecanoromycetes, Pezizomycotina, Ascomycota, Fungi. Kondratyuk et al. (2014) proposed Marchantiana (Teloschistaceae, Teloschistales, Lecanoromycetes) based on molecular, morphological and anatomical characters, with the type species Marchantiana occidentalis. The type species was initially identified as Caloplaca occidentalis by Kondratyuk et al. (2009). Marchantiana is treated as a monophyletic genus according to recent studies by using a combined data set (Wilk et al. 2021, Søchting et al. 2023) and is characterized by crustose thallus, exhibiting a continuous to areolate growth pattern, displays a range of colors from pale grey to dark brownish grey, dark greenish grey, or dull to bright yellow to orange. The cortical [...]

Fungalpedia - Note 464, Marinokulati    Marinokulati E.B.G. Jones & K.L. Pang Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Extreme-tolerant fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Juncigenaceae, Incertae sedis, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi. Based on the morphological and phylogenetic analyses, Chaetosphaeria chaetosa differs significantly from other Chaetosphaeria and Juncigena species (Jones et al. 2014). Therefore, the new genus Marinokulati was proposed to accommodate C. chaetosa by Jones et al. (2014), with the type species M. chaetosa. Chaetosphaeria chaetosa was described by Kohlmeyer (1963) and referred to Sphaeriaceae. However, Jones et al. (1983) mentioned that its taxonomic placement is unrelated to other Chaetosphaeria species, as it differs from other species in asci and ascospores with both polar and equatorial appendages, formed by fragmentation of an exosporic sheath, while no [...]
