Fungalpedia – Note 340, Geotrichites (Fossil fungi)   Geotrichites Stubblef. et al. 1985  Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fossil Fungi, Ascomycota, Saccharomycotina, Saccharomycetes, Saccharomycetidae, Saccharomycetales. Stubblefield et al. (1985) described the monotypic fossil genus Geotrichites from the Late Oligocene or Early Miocene (28.5–16 mya) sediments of Dominican Republic. Geotrichites includes aerial, erect or decumbent septate hyphae, and sometimes branching dichotomously. The conidiophores are micronematous. Conidia are holoarthric, aseptate, produced by schizolytic disarticulation, and variable in size, oblong, or truncate with obtuse ends. According to Stubblefield et al. (1985), Geotrichites conforms to the extant genus Geotrichum Link ex Pers. in most aspects, although it is impossible to determine whether the mycelium is dry or slimy in the fossilized state.  Type species: Geotrichites glaesarius Stubblef. C.E. Mill., [...]

  Fungalpedia – Note 312, Globobotrys   Globobotrys 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) introduced this monotypic genus based on Stachybotrys sansevieriicola (as Globobotrys sansevieriicola), which clustered distantly from the Stachybotrys s.str. clade in the phylogenetic analysis of cmdA, ITS, rpb2, and tub2 sequences. Globobotrys produce macronematous and mononematous conidiophores that occur in solitary or in groups. They are erect, mostly unbranched, 1(–2)-septate, and hyaline, with thin and smooth walls. Conidiogenous cells occur in whorls of 3–8, and the apices of conidiophores are phialidic, subcylindrical to clavate to widely reniform, hyaline, and pale brown. [...]

Fungalpedia - Note 200, Gloiodon    Gloiodon P. Karst.  Citation if using this entry: Bera et al. 2024 (in prep) – Fungalpedia, Basidiomycota 1.  Index Fungorum, MycoBank, Facesoffungi, GenBank, Fig. 1 Bondarzewiaceae, Russulales, Agaricomycetes, Basidiomycota, Fungi Gloiodon belongs to Bondarzewiaceae and was initially documented by the Finnish mycologist Karsten (1879). Originally,  Gloiodon was introduced to encompass three wood-inhabiting species exhibiting hydnoid hymenium, Hydnum strigosum Sw.:Fr., H. hirtum Fr. and H. pudorinum  Fr. (Karsten 1879, Desjardin & Ryvarden 2003). Later, Gloiodon, was confined to include solely Hydnum strigosum,, currently known as Gloiodon strigosus (Sw.) P. Karst. (Karsten 1879, Desjardin & Ryvarden 2003). Gloiodon strigosus was considered the type species of this genus by many mycologists over time (Banker 1902, 1910, Miller 1933, Donk 1956). This white rot-causing genus is characterized by annual, pileate, or effuse-reflexed basidiomata with its smooth to strigose surface texture (Desjardin & Ryvarden 2003). The basidiomata [...]

Fungalpedia - Note 147 Gomphidius    Gomphidius Fr.  Citation if using this entry: Bera et al. (in prep) – Fungalpedia, Basidiomycota 1. Mycosphere. Index Fungorum, MycoBank, Facesoffungi, GenBank, Fig. 1 Gomphidiaceae, Boletales, Agaricomycetes, Basidiomycota, Fungi The type genus of the family Gomphidiaceae was originally designated as Agaricus subgen. Gomphus Fr. but later, Fries (1825) raised it to the generic level and renamed it as Gomphidius. However, Fries did not initially designate a type species for the genus, but later, Gomphidius glutinosus (Schaeff.) Fr. was designated as the lectotype because it was the first species listed (Miller Jr 1971). The name "Gomphidius," is derived from the Greek word "gomphos," which means 'large wedge-shaped nail' or 'plug,' reflecting the shape of its basidiomata. As described by Singer (1949) and Miller Jr (1971), the genus is characterized by [...]

  Fungalpedia – Note  313, Grandibotrys   Grandibotrys 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 Grandibotrys for two stachybotrys-like taxa with large, olivaceous green to dark brown conidia that have a mammiform apical and/or basal protrudance. Furthermore, they clustered distantly from the Stachybotrys s.st clade in cmdA-ITS-rpb2-tub2 phylogeny (Lombard et al. 2016). Grandibotrys is characterized by macronematous mononematous conidiophores occur solitary or in groups, are erect, septate, unbranched or branched, hyaline with thin and smooth walls. The whorls of 2–4 conidiogenous cells arise from the apex of the conidiophores. They are phialidic, subcylindrical to clavate to fusiform, hyaline and smooth-walled with [...]

Fungalpedia – Note 341, Graphiolites (Fossil fungi)   Graphiolites Fritel 1910 Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fossil Fungi, Basidiomycota, Ustilaginomycotina, Exobasidiomycetes, Exobasidiomycetidae, Exobasidiales, Graphiolaceae. Graphiolites, was described by Fritel (1910) from the Sparnacian (Early Eocene, 55.5 mya) sediments of Cessoy, Seine-et-Marne, France. The genus includes fossil forms of which the external features and habitat agree with those of the extant Graphiola, i.e. fungi specialized in parasitizing palm fronds, where they form peridia consisting of deep, round or oval cupules. These cupules may be dispersed or arranged in a longitudinal series, parallel to the nervature of the fronds on which they grow. When the peridia are oval, the longer axis is always longitudinally aligned. Fritel (1910), for the first time, [...]

  Fungalpedia – Note 314, Gregatothecium   Gregatothecium 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 Gregatothecium for a single taxon, that is morphologically similar to Calonectria, Cylindrocladiella and Dematiocladiella (Lombard et al. 2015), but phylogenetically related to Stachybotriaceae in the analysis of cmdA, ITS, rpb2 and tub2 sequences. Gregatothecium can be distinguished from these three genera by its slimy olivaceous-green conidial masses (Lombard et al. 2015, 2016). Gregatothecium produces sporodochial conidiomata consisting of multiple aggregated penicillate conidiophores or is reduced to penicillate or subverticillate solitary conidiophores. Sporodochia are superficially arranged, scattered or gregarious, stromatic and orbicular or irregular in shape. They possess olivaceous green slimy masses [...]

Fungalpedia - Note 226, Guayaquilia   Guayaquilia R.F. Castañeda, Magdana, D. Sosa & Hern. -Restr.  Citation when using this entry: Doilom et al. 2024 (in prep) – Fungalpedia, Xylariomycetidae.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Incertae sedis, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi. Based on the phylogenetic analysis of the combined LSU and ITS sequences revealed that three strains (MUCL 39017, CCMCIBE-H312, and CCMCIBE-H320), identified as Idriella cubensis formed a monophyletic lineage distinct from a clade containing I. lunata (the generic type). These strains were phylogenetically distant from Microdochiaceae (Xylariales). Therefore, Magdama et al. (2020) established a new genus Guayaquilia to accommodate Guayaquilia cubensis (≡ I. cubensis (Castañeda & Arnold 1985) based on morphological and phylogenetic analyses. Guayaquilia has been reported as a saprobic collected from decaying leaves of Theobroma cacao (Malvaceae) in Ecuador, as well as from decaying [...]

Fungalpedia – Note 221, Guestia   Guestia G.J.D. Sm. & K.D. Hyde Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Citation when using this entry: Li et al. 2024 (in prep) – Fungalpedia,  Xylariomycetidae.  Classification: Xylariaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Guestia was introduced by Smith & Hyde (2001) in Xylariaceae based on morphology with G. gonetropospora as the type species. This genus consists with only one species (Species Fungorum 2024), which has been reported as saprobe collected from dead rachis of Mauritia flexuosa (palm) in Ecuador. Guestia is characterized by pseudostromata with 1–4 ascomata, black, conical, or hemispherical stromata, with a thin and patchy, 8-spored, unitunicate asci with amyloid apical rings, inequilateral ascospores, and dark germ slit (Smith & Hyde 2001). Wendt et al. (2018) accepted Guestia within the Xylariales genera incertae sedis based on only known morphological descriptions of [...]

Fungalpedia – Note 102, Halodiatrype   Halodiatrype Dayarathne & 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: Diatrypaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Dayarathne et al. (2016) introduced Halodiatrype with Halodiatrype salinicola as the type. Later, Dayarathne et al. (2020) emended the genus with asexual morphs. Halodiatrype is characterized by the presence or absence of ascostromata or pseudostromata. If ascostromata or pseudostromata are present, they are effused, embedded in decorticated wood, incorporate host tissues, are somewhat eutypoid, and blacken the host surface. Perithecia solitary to scattered, immersed, dark brown to black, globose to subglobose, papillate, and ostiolate with central ostioles. Occasionally, the apex of the ostiole is made up of a brown outer amorphous [...]
