Fungalpedia - Note 31 Canasta   Canasta A.A. Carvalho & J.F. Hennen (a synonym of Prospodium) Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep) Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. The asexual genus Canasta with the type species Canasta cruscula was established by Carvalho & Hennen (2010) in Uropyxidaceae, Pucciniales. The genus accommodated three other species, Canasta amphilophii López-Alzate & Salazar-Yepes, Canasta garcesii (F. Kern & Thurst.) A.A. Carvalho & J.F. Hennen, and Canasta oblata A.A. Carvalho & J.F. Hennen, with most causing rust on Bignoniaceae. Canasta is closely related to the genus Prospodium, so that the generic name Canasta was introduced for asexual morphs of species of Prospodium, although the type species Canasta cruscula does not have known sexual morphs. The other three species mentioned in Canasta have sexual morphs that are species of Prospodium. So, based on this evidence, Aime et al. (2018) suggested that Canasta is probably a synonym [...]

Fungalpedia - Note 195, Cantharellus    Cantharellus Adans. ex Fr. Citation if using this entry: Bera et al. 2024 (in prep) – Fungalpedia, Basidiomycota 1.  Index Fungorum, MycoBank, Facesoffungi, GenBank, Fig. 1 Classification: Cantharellaceae, Cantharellales, Agaricomycetes, Basidiomycota, Fungi Cantharellus, frequently referred to as “chanterelles” is one of the highly regarded edible mushrooms since medieval times for its culinary-medicinal activity  (Danell 1994, 1999, Muszyńska et al. 2016).  However, the taxonomic classification of this genus has been a subject of controversy for an extended period. The generic concept of Cantharellus has significantly evolved over the years (Buyck et al. 2014). For a considerable time, “Cantharellus” was used as an umbrella name for all the taxa having characteristic veins or “false gills” instead of distinct gills in hymenium. Evidently, Cantharellus has frequently been mistaken for Craterellus Pers. With the progress in micro-morphological [...]

Fungalpedia – Note 309, Capitofimbria   Capitofimbria 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) established the monotypic genus Capitofimbria for Myrothecium compactum, which clustered distant to the Myrothecium s.str. clade in the analysis of cmdA, ITS, rpb2, and tub2 loci. Capitofimbria is characterized by sporodochial conidiomata that occur superficially on the substrate, and are stromatic, scattered, or rarely gregarious. Conidiomata are oval to irregular in outline, amphigenous, pulvinate, with olivaceous green to dark green slimy mass of conidia and lack a white setose fringe surrounding the conidial mass. Stromas are hyaline to subhyaline and well-developed with globulosa and angularis [...]

Fungalpedia – Note 91 Castanedomyces   Castanedomyces Cano, L.B. Pitarch & Guarro Citation when using this entry: Thakshila et al., in prep – Fungalpedia, Onygenales, Eurotiales and Verrucariales. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 The monotypic genus Castanedomyces was introduced by Cano et al. (2002) in the family Onygenaceae (Onygenales, Eurotiomycetidae, Eurotiomycetes). The genus is typified by C. australiensis which was isolated from soil samples from Mount Lofty in South Australia (Cano et al. 2002). Only the sexual state has been reported. Based on 18S rDNA sequences, C. australiensis clustered with Aphanoascus fulvescens (Cano et al. 2002). Castanedomyces australiensis is morphologically similar to A. fulvescens in having a membranous peridium (only found in a few onygenalean genera) and lenticular ascospores with an equatorial crest and polar thickenings (Cano & Guarro 1990). However, the pseudoparenchymatous [...]

Fungalpedia – Note 347, Catathelasma   Catathelasma Lovejoy.             Citation if using this entry: Khyaju et al. 2025 (in prep.) – Fungalpedia, Basidiomycota 4. Index Fungorum, FaceofFungi, Mycobank, GenBank, Fig. 1 Classification: Biannulariaceae, Agaricales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi             Catathelasma was established by Ruth Harrison Lovejoy with Catathelasma evanescens as the type species (Lovejoy 1910, Ge et al. 2020). Species of Catathelasma are known to be ectomycorrhizal (Trappe 1962, Tedersoo & Smith 2013, Ge et al. 2020). Catathelasma was initially classified under Tricholomataceae and later reclassified into Biannulariaceae (Singer 1975, Jülich 1982, Singer 1986, Ge et al. 2020). The type specimen was collected from open balsam and spruce woods occurring singly in sod on thick humus in Wyoming, United States of America (Lovejoy 1910). The Global [...]

Fungalpedia – Note 160, Ceratohirudispora (Fossil fungi)   Ceratohirudispora R. Kar, Mand. & R.K. Kar. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1             Classification: Phragmosporae, Fungi. Kar et al. (2010) introduced Ceratohirudispora from the Bhuban Formation (Early Miocene, 23–16 mya) of Tlangsam, Mizoram, India. This genus is characterized by the following diagnosis: Hyphomycetaceous fungi with small conidiophore, growth terminated by the production of apical conidium. The conidium enlarges laterally in opposite direction to produce two–three arms. Conidia are 5–10 celled, with septa up to 2 μm thick, with a broad base and narrow tip. The conidia of C. miocenica Kar et al. 2010 (Type) is two-armed and V-shaped (Fig. 1a), while the C. triradiata Kar et al. 2010 is three-armed and triradiate (Fig. 1b). Two species are [...]

Fungalpedia – Note 161, Cervichlamydospora (Fossil fungi)   Cervichlamydospora R. Kar, Mand. & R.K. Kar.  Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Phragmosporae, Fossil Ascomycota, Fungi The monotypic genus Cervichlamydospora was described by Kar et al. (2010) from the Bhuban Formation (Early Miocene, 23–16 mya) in Tlangsam, Mizoram, India, with the following diagnosis: Chlamydospores are subcircular and dark brown-black, originate from neck of hyphae. They are solitary, and many hyphae adhere together at base, branch out laterally at tip. The hyphae wall is laevigategranulose, with grana up to 1 μm thick and sparsely placed. Only one species listed in Index Fungorum (2023) under this genus. Type species: Cervichlamydospora nigra R. Kar, Mand. & R.K. Kar.     Figure 1 – Cervichlamydospora nigra. Scale bar = 10 μm. Redrawn from Kar et al. (2010).   [...]

Fungalpedia  -Note 21 Chaetomella   Chaetomella Fuckel, (1870) Citation when using this data: Huanraluek et al. Fungalpedia, coelomycetes, Mycosphere (in press)  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. Based on phylogenies of SSU and LSU sequence data, Chaetomella was transferred to Leotiomycetes (Chaetomellaceae Chaetomellales, Leotiomycetes) (Li et al. 2020). The type species is Chaetomella oblonga, and is a coelomycete. Species of this genus are characterized by pycnidial or sporodochial conidiomata with brown, unbranched setae, long, acropleurogenous conidiophores, and hyaline ellipsoid to fusiform or falcate, unicellular conidia (Sutton 1980, Rossman et al. 2004). Chaetomella is saprobic or parasitic on the host plant in terrestrial habitats or has been isolated from soil (Li et al. 2020). This genus is distributed in Australia, Canada, India, Zambia and the USA (Rossman et al. 2004, Crous et al. 2014, 2019).  Chaetomella comprises 60 species that have been recorded in Index [...]

Fungalpedia – Note 163 Chaetosphaerites (Fossil Fungi)   Chaetosphaerites Felix 1894 (Fossil). Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Phragmosporae, Fossil Fungi.  Felix (1894) instituted Chaetosphaerites from the Eocene (56–34 mya) sediments of Perekeschkul, near Baku, Azerbaijan. Felix (1894) stated that some silicified spores are characterized particularly by the dark brown middle and pale brown end cells. Since the boundaries of the respective colours coincide exactly with the sharp delimitations of the individual segments, it is probably not justified to assume that the differences in shade only resulted from the state of preservation. It is unlikely, particularly in view of the minute size of the objects, for differences to occur in the state of preservation of the individual parts. Additionally, within the genera Chaetosphaeria, Lophiostoma, Massaria, and [...]

Fungalpedia – Note 263, Chamonixia   Chamonixia Rolland.             Citation if using this entry: Khyaju et al. 2024 (in prep.) Basidiomycota 4. Index Fungorum, FacesofFungi, Mycobank, GenBank Fig.1 Classification: Boletaceae, Boletales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi             Chamonixia Rolland was established by Rolland (1899), which accommodated Chamonixia caespitosa Rolland from France as the type species (Mleczko et al. 2009, Orihara et al. 2016). Chamonixia is a sequestrated descendant of epigeous boletes (Orihara et al. 2016). Chamonixia is characterized by gasterioid, spongy, white, fibrillose basidiomata, which often turn blue when bruised (Rolland 1899, Mleczko et al. 2009, Orihara et al. 2016). The hymephore is located in small round to oval chambers, initially pale turning brown, and lacking a stipe (Rolland 1899, Mleczko et al. [...]
