(2024) in prep – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fungi Incertae sedis, Amerosporae. The monotypic fossil genus, Exesisporites, was described from the Northern Gulf of Mexico's Miocene-Pleistocene (23–2 mya) sediments (Elsik 1969). This genus is characterized by unicellular, aseptate, psilate, and monoporate spores with a circular outline and a lenticular to spherical shape. It has a centrally located pore, which in most specimens is surrounded by a dark circular patch that is interpreted as a thickened wall.

Fungalpedia – Note 333, Foliopollenites (Fossil fungi)   Foliopollenites Sierotin. 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, Incertae sedis, Amerosporae. Sierotin (1861) described the monotypic fossil genus, Foliopollenites, from the Early Jurassic (201–174 mya) sediments of Germany. Foliopollenites includes fossil fungal spores shaped like a tapered leaf and surface covered with numerous spines of a little over 1 μm long. Spore wall is two layered, a little more than 1 μm thick, surface chagrinate. Size 27 × 21 μm. Potonié (1966) quoted a letter from Sierotin that “possibly this is a microfossil that can be assigned elsewhere” (than in the flowering plants). After the original publication of the genus (Sierotin 1861), two more species were allocated [...]

Fungalpedia – Note 184, Foveodiporites (Fossil Fungi)   Foveodiporites Varma & Rawat emend. Kalgutkar & Janson. Citation when using this data: Saxena RK & Hyde KD. (2024) in prep – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Amerosporae, Fossil Fungi. The monotypic fossil genus, Foveodiporites, was described by Varma & Rawat (1963) based on specimens from the Early-Middle Eocene (ca. 56–38 mya), Late Eocene-Oligocene (ca. 38–23 mya), and Early Miocene (ca. 23–16 mya) sediments of western and eastern India, including oil exploration areas in West Bengal and Assam, India. The short diagnosis of this genus, included diporate pollen grains with foveolate exine (Varma & Rawat 1963). Although originally described as pollen, these forms are now generally recognized as fungal spores. Consequently, Kalgutkar & Jansonius (2000) emended the generic diagnosis as follows: Monocellate diporate fungal spores of mostly medium size (ca [...]

Fungalpedia - Note 233, Frondicola   Frondicola K.D. Hyde. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Citation when using this entry: Li et al. 2024 (in prep) – Fungalpedia, Xylariomycetidae.  Classification: Hyponectriaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi. Frondicola was established by Hyde (1992), based on morphology. The type species, F. tunitricuspis was found on the decaying fronds of Nypa fruticans (Arecaceae) in the intertidal region of the South China Sea (Brunei). Frondicola has dark ascomata with central ostiolar dots, immersed beneath a clypeus with variable stromatic development, septate paraphyses, tapering towards the apices, 8-spored, cylindrical asci, short pedunculate, with J-, apical ring, uniseriate, hyaline, ellipsoidal ascospores, and surrounded by a mucilaginous sheath (Hyde 1992).  The presence of paraphyses attached to asci excludes this genus from Diaporthaceae, while most Phyllachoraceae are parasitic and distinguishable by their soft clypeus and more delicate asci (Hyde 1992). It [...]

Fungalpedia – Note 93 Fusarium   Fusarium Link Citation when using this entry: Gomdola et al., in prep – Fungalpedia, forest pathogenic fungi. Mycosphere. Index Fungorum, MycoBank, Facesoffungi, GenBank, Fig 1 Fusarium (Gibberella) was established and described by Link (1809) based on morphological characters, depicted by its conspicuous banana or canoe-shaped conidia. Fusarium roseum was designated as the type species. In 1821, the nomenclature of Fusarium was sanctioned by Fries, followed by the first monograph (Appel and Wollenweber 1910). Subsequently, many studies employing multiple approaches to revise the genus and delineate its species were carried out (Wollenweber 1935; Booth 1971; Crous et al. 2021; Yilmaz et al. 2021; Wang et al. 2022). Fusarium belongs to Nectriaceae (Hypocreales, Hypocreomycetidae, Sordariomycetes) (Maharachchikumbura et al. 2016; Hyde et al. 2020; Wijayawardene et al. 2020, 2022; Index Fungorum 2023). To date, 1742 and 433 species epithets are listed in Index Fungorum and Species [...]

Camus Citation when using this entry: Selçuk et al., in prep – Genera and higher taxa introduced in 2023. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 This genus is monotypic, which is the causative agent of tetra disseminated microsporidiosis, a new disease in ornamental fish of cardinal tetra and black tetra. The non-xenoma-forming microsporidium occurred diffusely in most internal organs and the gills, thus referring to the condition as tetra disseminated microsporidiosis. Based on combined phylogenetic and ultrastructural characteristics, the genus  was proposed by Lovy et al. (2021), with F. stethaprioni as the type species. In microscopic preparations, spores were uniform measuring 3.9 ± 0.33 μm (range = 3.2–3.7 μm) x [...]

Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Microascaceae, Microascales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Jagielski et al. (2016) described the monotypic genus Fuscoannellis, which is typified by scopulariopsis-like taxon Scopulariopsis carbonaria. Fuscoannellis species occur on unidentified pyrenomycetes, dead hardwood, and soil (Jagielski et al. 2016; Woudenberg et al. 2017). The genus is characterized by moderately spreading colonies that are greenish grey, dark grey to black, and velvety to funiculose. The conidiophores are either unbranched or branched. Unbranched conidiophores terminally bear a compact group of 2–10 conidiogenous cells. Branched conidiophores are more frequent, with several stages of branching, each branch terminally swelling and bearing a compact group [...]

Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fungi, Fossil Ascomycota, Incertae sedis, Amerosporae. The monotypic fossil genus Fusidiporosporonites was described by Song et al. (1989) from the Shahejie Formation (Late Eocene-Middle Oligocene, 38–20 mya) of Shenxian County of Shandong Province, China. This genus includes one-celled spores that are narrowly fusiform in outline and tapered to form a short tube at each terminal end. The spores had two pores situated at the tips of the short tubes. Pores are simple and unstructured, Spore wall is moderately thick, variously ornamented, but commonly thin and weak. According to Song et al. (1989), the ornamentation and shape of the type species are similar to those of Lacrimasporonites minutaestriatus P. [...]
