Fungalpedia - Note 14 Coremiostelium   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Coremiostelium S. Baldauf, S. Sheikh & Thulin Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Dictyostelids, a group of cellular slime molds or social amoebae, are commonly found in a wide range of soils and play important ecological roles as predators of soil bacteria (Sheikh et al. 2018). Dictyostelids taxa were informally classified into eight distinct clades and three complex groups namely polycarpum, polycephalum and violaceum (Romeralo et al. 2011), however, this classification was in conflict with molecular evidence (Schaap et al. 2006, Romeralo et al. 2007). Sheikh et al. (2018) refined the taxonomy and proposed a new classification of dictyostelids based on the only marker available for most dictyostelids, SSU rDNA data. They proposed the polycephalum complex as a new genus Coremiostelium, which refers to Dictyosteliales genera incertae sedis. Coremiostelium species are characterized by colorless [...]

Fungalpedia – Note 298, Corticimorbus   Corticimorbus S.F. Chen & M.J. Wingf Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Cryphonectriaceae, Diaporthales, Diaporthomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Chen et al. (2016) established monotypic genus Corticimorbus with C. sinomyrti as the type. The taxon was placed in Cryphonectriaceae based on LSU, 5.8S rDNA and the exon regions of the BT2 and BT1 (Chen et al. 2016). Corticimorbus is characterized by gregarious or single, superficial to slightly immersed, orange to umber and pulvinate ascostromata on bark. Cells of the ascostromatic tissue are forming a textura globulosa and covering the tops of the perithecial bases. Perithecia are fuscous black, valsoid with globose to sub-globose bases. They are embedded beneath the surface of bark [...]

Fungalpedia - Note 15 Crassiperidium   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Crassiperidium M. Matsum. & Kaz. Tanaka Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Crassiperidium was established by Matsumara et al. (2018) to accommodate two new species isolated from dead twigs of Fagus crenata in Japan. Based on the combined SSU, LSU, and rpb2 sequence analysis, Crassiperidium formed a sister clade with Cyclothyriella rubronata and Massariosphaeria phaeospora, but this relationship was not well-supported (Matsumara et al. 2018). Moreover, morphological characteristics of the ascospores and the conidiogenesis of Crassiperidium species differ from those of the two genera. This was resolved by Phukhamsakda et al. (2020) who introduced the family Longiostiolaceae (Pleosporales), to accommodate Crassiperidium species and Longiostiolum tectonae.  Longiostiolaceae formed a well-supported clade with Cyclothyriellaceae as a sister clade based on LSU, SSU, ITS, tef1 [...]

Fungalpedia - Note 61 Craterellus   Craterellus Pers. Citation if using this entry: Bera et al. (2023) Fungalpedia, Basidiomycota. Mycosphere (in prep) Index Fungorum, MycoBank, GenBank, Fig. 1   In the phylogenetic study by Hibbett and Thorn (2001), a cantharelloid clade was first recognized to accommodate this morpho-diverse group of mushrooms which clustered with the chanterelles group. With Craterellus, the name Cantharellus has consistently been linked in the chanterelles group which is characterized mainly by the no strict division between the pileus and the stipe and the presence of “false gills” (Dahlman et al. 2000). Fries (1821) originally defined Cantharellus, but later Persoon (1825) separated some species with hollow stipes and erected Craterellus. However, the distinction between these two genera has always been controversial (Corner 1966, Petersen 1971). The genus Craterellus Pers., typified with C. cornucopioides (L.) Pers. (Persoon 1825), is [...]

Fungalpedia - Note 197, Crepidotus    Crepidotus (Fr.) Staude    Citation if using this entry: Bera et al. 2024 (in prep) – Fungalpedia, Basidiomycota 1.  Index Fungorum, MycoBank, Facesoffungi, GenBank, Fig. 1 Classification: Crepidotaceae, Agaricales, Agaricomycetes, Basidiomycota, Fungi Fries (1821) initially categorized Crepidotus under Agaricus trib. Crepidotus Fr., which included pleurotoid taxa with fibrillose veil and pale or ferruginous basidiospores (Senn-Irlet 1995). However, Crepidotus was later raised to the generic rank by Staude (1857) (Donk 1949, Consiglio & Setti 2008, Na et al. 2022). The tribe Crepidotus used to encompass eight species, most of which have been transferred to two current genera: Entoloma (Fr.) P. Kumm. and Tapinella E.-J. Gilbert E.-J. Gilbert, leaving only three species that persisted within Crepidotus (Consiglio & Setti 2008, Na et al. 2022). The first contributions towards the diversity of this [...]

Fungalpedia - Note 10 Crispospora   Crispospora Y.S. Tokarev, V.N. Voronin, E.V. Seliverstova, O.A. Pavlova & I.V. Issi   Citation if using this entry: Fahalli et al. (2023) New genera in 2010-2011. Mycosphere (in press) Index Fungorum Identifier 646569, Facesoffungi, MycoBank, GenBank, Fig 1. The monotypic genus Crispospora with type species Crispospora chironomid was established in Microsporidia, Protozoa by Tokarev et al. (2010). Crispospora chironomid was isolated from larval adipose tissue of Chironomus plumosus in northwest European Russia. The parasite invades the gut epithelium of the host larvae and has two types of sporogonies, polysporoblastic and disporoblastic, both develop within the same host cell. A thick-walled capsule with several spherical monokaryotic spores is generated in the first type of sporogonial sequence (Tokarev et al. 2010). Diplokaryotic oval spores in the second type of sporogonial, form within a compartment that is partially encircled with multilayered [...]

Fungalpedia - Note 257, Cryphonectria   Cryphonectria (Sacc.) Sacc. & D. Sacc.  Citation when using this entry: Aumentado et al. 2024 (in prep) – Fungalpedia, plant pathogens.   Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1.  Classification: Cryphonectriaceae, Diaporthales, Diaporthomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi  Cryphonectria belongs to Cryphonectriaceae (Diaporthales) (Gryzenhout et al. 2006a, 2006b), and was established to incorporate Nectria abscondita and N. variicolor, although the type species were not specified (Saccardo & Saccardo 1905, Jiang et al. 2018). Hence, Gryzenhout et al. (2005) proposed Cryphonectria parasitica as the type species of Cryphonectria, which is known to cause chestnut blight. The defining sexual characteristics of Cryphonectria include clustered or solitary, partially embedded, protruding orange ascostromata. The ascostromata are cylindrical-fusoid to club-shaped, attached to pedicels, and contain eight-spored asci exhibiting distinctive refractive J-shaped rings. The ascospores are elliptical, spindle-shaped, cylindrical, aseptate, typically transparent [...]

Fungalpedia - Note 357, Cryptomarasmius    Cryptomarasmius T.S. Jenkinson & Desjardin Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Parasites. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Physalacriaceae, Agaricales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi Cryptomarasmius contains the term "crypto," meaning "hidden," and it is combined with another word, Marasmius. This alludes to the historical association of the species with Marasmius as well as the frequently concealed, diminutive fruit bodies they generate. This genus was established by Jenkinson et al. (2014) and typified with Cryptomarasmius corbariensis. Cryptomarasmius is characterized by diminutive, marcescent, convex basidiomes, ranging from smooth to rugulose, occasionally spinulose, and may even or striate. They are dry, typically darkly pigmented, and pallid infrequently. The lamellae range from vein-like to well-developed, seldom absent, and possess a smooth hymenophore. They are free to adnate, never collariate, and remote to subdistant, appearing pallid. [...]

Fungalpedia – Note 167, Cucurbitariaceites (Fossil Fungi)   Cucurbitariaceites R.K. Kar, R.Y. Singh & S.C.D. Sah. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Dothideales, Fossil Ascomycota, Fungi The monotypic fossil genus Cucurbitariaceites was described by Kar et al. (1972) from the Tura Formation (Palaeocene, 66–56 mya) in Nongwal Bibra, Garo Hills, Meghalaya, India. This genus is characterized by subcircular to circular Pseudoperithecia, outer region darker than inner, laevigate. Asci are equal or unequal in size, cylindrical to somewhat bulging at the tips in the mature stage. No true paraphysis was observed, but in some specimens, the basal part of asci may join together to form a broad, irregular, mesh-like structure. Cucurbitariaceites bellus has been recorded from various states of India, e.g. Andaman [...]

Fungalpedia – Note 310, Cymostachys   Cymostachys L. Lombard & Crous 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 Cymostachys for a group of stachybotrys-like taxa that produce irregularly cymosely branched conidiophores and olivaceous brown to dark brown, fabiform conidia. Furthermore, they are distantly related to Stachybotrys s. str. in the phylogenetic analysis of cmdA, ITS, rpb2, and tub2 (Lombard et al. 2016). The conidiophores are macronematous, mononematous and arrange mostly in groups. They are erect, septate, irregularly cymosely branched, and hyaline to subhyaline, with thin and smooth to slightly verrucose walls. The conidiophores generated 3–6 phialidic conidiogenous cells from the [...]
