 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 30 Marinophialophora   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Marinophialophora J.F. Li, Phookamsak & K.D. Hyde              Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1             Marinophialophora is a monotypic genus in Herpotrichiellaceae, Chaetothyriales and it is only known from its asexual morph (Li et al. 2018, Tian et al. 2021). This genus was introduced to accommodate a hyphomycetous species that is associated with Halocyphina species (Niaceae, Agaricales) on the intertidal decaying wood of mangroves (Li et al. 2018). Marinophialophora garethjonesii is the type species and this genus is characterized by superficial or immersed, septate, branched, smooth, thin-walled hyaline to subhyaline mycelia on the substrate. Conidiophores arising from hyphae are hyaline to subhyaline, aseptate, thin-walled, smooth, macronematous, mononematous, and straight. Conidiogenous cells are phialidic, terminal or intercalary, globose [...]

Fungalpedia - Note 20Marjia   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Marjia Wanas., Gafforov & K.D. Hyde Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1             Marjia was established by Wanasinghe et al. (2018) with the generic type M. tianschanica plus M. uzbekistanica, and placed it in Melanommataceae. Only the sexual morph is reported for Marjia and characterized by superficial, broadly oblong, coriaceous ascomata, with a thick peridium composed of dark brown to black cells of textura angularis, filamentous and branched pseudoparaphyses with septa, cylindrical to cylindric-clavate asci with long pedicels, and ellipsoidal to subfusiform, muriformly septate, brown ascospores (Wanasinghe et al. 2018, Hongsanan et al. 2020). Marjia species are similar to the members of several genera in Melanommataceae, viz. Gemmamyces, Melanocucurbitaria, [...]

Fungalpedia – Note 239, Mathurisporites (Fossil Fungi)   Mathurisporites Kalgutkar & Jansonius. Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fossil Ascomycota, Incertae sedis, Fungi  The monotypic fossil genus Mathurisporites was instituted by Kalgutkar & Jansonius (2000) to accommodate Pluricellaesporites ellipticus, originally described by Mathur & Mathur (1969), from the Pliocene (5.3–2.6 mya) sediments of Naera and Baraia, Kutch District, Gujarat, India. Mathurisporites includes medium sized hilate spores, generally consisting of a darker central part with 2–4(–6) cells, and proximal and distal parts of a single to few hyaline cells. No distal pore is observed. Septa distinct, as thick as or thicker than the spore wall. This genus differs from Pluricellaesporites in the swollen dark central cells. The generic name honours [...]

Fungalpedia – Note 88 Megacoelomyces   Megacoelomyces Dianese, Guterres, M.D.M. Santos & G.F. Sepúlveda  Citation when using this entry: Pem et al., in prep – Genera of Dothideomycetes Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. Dos Santos et al. (2020) introduced Megacoelomyces to accommodate M. sanchezi based on morphology and analysis of combined ITS and LSU sequence data. Megacoelomyces sanchezi was collected on trichomes of living leaves of Myrcia fenzliana (Myrtaceae) in Brazil (Dos Santos et al. 2020). Megacoelomyces is known only from its asexual state, and is characterized by large, superficial, barely setose pycnidial conidiomata situated on a loose, trichome-associated subiculum. Megacoelomyces resembles Callistospora (Ascomycota incertae sedis), Orphanocoela (Pezizomycotina incertae sedis) and Urohendersoniella (Pezizomycotina incertae sedis) in having pycnidial, dematiaceous coelomyceteous morph with appendiculate, phragmosporous, or distoseptate conidia, but phylogenetic evidence obtained from analysis [...]

Fungalpedia - Note 22 Melanocucurbitaria   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Melanocucurbitaria Wanas., Gafforov & K.D. Hyde Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Wanasinghe et al. (2018) introduced Melanocucurbitaria based on phylogenetic analyses of ITS, LSU, SSU and tef sequence data. Melanocucurbitaria clustered separately from other Melanommataceae genera, but, with poor statistical support. The genus has muriform ascospores similar to Gemmamyces, Muriformistrickeria, Pseudostrickeria and Praetumpfia. Melanocucurbitaria differs from the above-mentioned genera by the production of significantly larger ascomata and a thin peridium (Wanasinghe et al. 2018). Currently, the genus is monotypic with only the type species which was identified in Uzbekistan on branches of Acer pubescens. The asci and ascospores of the fungus resemble those of Cucurbitaria species. However, a clear distinction can be observed in the peridium, whereby [...]
