Fungalpedia – Note 534, Middelhovenomyces    Middelhovenomyces Kurtzman & Robnett Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Yeast. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Incertae sedis, Saccharomycetales, Saccharomycetidae, Saccharomycetes, Saccharomycotina, Ascomycota, Fungi. Kurtzman and Robnett (2014) combined Candida petrohuensis and C. tepae as Middelhovenomyces petrohuensis and M. tepae to establish a new non-ascosporic, ascomycetous yeast genus. Middelhovenomyces was introduced to accommodate M. petrohuensis and M. tepae (the type species) based on current descriptions and phylogenetic analyses (D1/D2 large subunit rRNA, small subunit rRNA, translation elongation factor-1α and RNA polymerase II, subunits B1and B2). Members of Middelhovenomyces are found in rotted wood. Growth of Middelhovenomyces occurs via multilateral budding and formation of pseudohyphae. Sugar fermentation was not observed. Phylogenetically, the genus Middelhovenomyces is most closely related to Diddensiella and Zygoascus (Kurtzman & Robnett 2014).

(2014) proposed Mikhtomia (Teloschistaceae, Teloschistales, Lecanoromycetes) based on molecular, morphological, and anatomical characters, with the type species Mikhtomia gordejevii. The type species of this genus was initially introduced as Placodium gordejevii by Tomin (1926). Mikhtomia species have the following morphological characters: thallus are crustose, continuous to areolate, the color ranges from dull greenish grey to dark greenish or grey, or dull to bright yellow or orange, with a palisade paraplectenchymatous cortical layer. Oil droplets are plentifully dispersed throughout apothecia biatorine, subhymenium, and the lower part of the hymenium; true exciple of [...]

Fungalpedia – Note 229, Milesites (Fossil Fungi)   Milesites Ramanujam & Ramachar. Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1              Classification: Milesinaceae, Pucciniales, Pucciniomycetes, Fossil Basidiomycota The monotypic fossil genus, Milesites, was described by Ramanujam & Ramachar (1980) from the Neyveli lignite (Miocene, 23–5 mya) of Cuddalore Distroict, Tamil Nadu, India. It includes obscurely pedicellate, obovoid, lanceolate, or irregularly configured urediniospores having thin (up to 1.5 μm thick), hyaline or very light-coloured, smooth or finely sculptured walls and a few faint/indistinct germ pores. According to Ramanujam & Ramachar (1980), the fossil spores of Milesites show similarity with the urediniospores of extant Milesia F.B. White, parasitizing members of the fern family Polypodiaceae. Interestingly, polypodiaceous spores are common in Neyveli lignite. Type species: Milesites irregularis Ramanujam & Ramachar.   [...]

Fungalpedia - Note 44 Millerozyma   Millerozyma Kurtzman & M. Suzuki Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep) Index Fungorum, MycoBank, GenBank, Fig1 To evaluate the evolutionary position of the yeast species of Pichia and species from nearby genera that make coenzyme Q-9, Kurtzman and Suzuki (2010) surveyed the divergent domains of the large subunit (D1/D2) and the almost complete small subunit rDNA (18S rDNA). They proposed the genus Millerozyma in Debaryomycetaceae (Saccharomycetales), with two ascomycetous yeast species, Millerozyma acaciae, and Millerozyma farinosa. Later, Tammawong et al. (2010), based on phenotypic and phylogenetic data (based on D1/D2 domain of LSU rDNA and ITS), added Millerozyma phetchabunensis to this genus. They also transferred Pichia koratensis, which was placed in the Millerozyma clade, to Millerozyma as Millerozyma koratensis. Mallet et al. (2012) also proposed Millerozyma miso as a new species in this genus. The genus members are characterized by conjugated [...]

Arias Citation when using this entry: Madagammana et al. 2024 (in prep) – Fungalpedia, genera described in 2012.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1. Classification: Pezizomycotina, Ascomycota, Fungi             Minteriella is an asexual genus introduced by Heredia et al. (2012), based on morphology, and typified by M. cenotigena. Minteriella is characterized by scattered, synnematous conidiomata and superficial and immersed mycelia. Conidiophores are differentiated, septate, brown, simple, or branched, and the conidiomata are polyblastic, discrete, and indeterminate with sympodial proliferations. The conidiogenous loci are flat, unthickened, apical, and intercalary. Conidia exhibit schizolytic conidial secession, with solitary, acropleurogenous, multiseptate, cylindrical to broad filiform, subhyaline or hyaline, with a smooth wall (Heredia et al. 2012).  Minteriella resembles Chikaneea, Cylindrosympodium, Pleurotheciopsis, Polyscytalum, [...]

Fungalpedia - Note 359, Mitosporidium   Mitosporidium K.L. Haag, T.Y. James, Pombert, R. Larsson, T.M.M. Schaer, D. Refardt & D. Ebert Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, parasites. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig.1            Classification: Incertae sedis, Incertae sedis, Incertae sedis, Rozellidea, Paramycia, Choanozoa, Protozoa The new genus Mitosporidium was formally established by Haag et al. (2014) and typified with Mitosporidium daphniae. This species has been documented to be parasitic on the crustacean Daphnia magna in northwestern Europe (Belgium, Germany, and the United Kingdom). This has been utilized in prior studies without formal classification, where it was shown to have a negative impact on the host's fitness (Refardt et al. 2012, Haag et al. 2014). The morphological characteristics of Mitosporidium share similarity to the Microsporidia, has retained genomic features inherited from its fungal ancestors. Mitosporidium was characterized by thin, three-layered spore wall (electron opaque exospore and wide, electron lucent [...]

Fungalpedia – Note 103 Moheitospora   Moheitospora Abdel-Wahab, Abdel-Aziz & Nagahama Citation when using this entry: Asghari et al., in prep – Fungalpedia, genera of salt marsh fungi. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Abdel-Wahab et al. (2010) described Moheitospora as a novel genus in the order Hypocreales based on morphological and phylogenetic data. Later the genus was transferred to the family Juncigenaceae (Torpedosporales) (Jones et al. 2015) and was followed in Wijayawardene et al. (2022). The genus was classified with other marine fungi in the TBM (Torpedospora/Bertia/Melanospora) clade based on phylogenetic analysis of LSU and SSU rDNA sequences. Moheitospora conidiophores form acrogenous or laterally on the hyphae, with monoblastic, integrated, terminal conidiogenous cells. Conidia are irregularly helicoid, with densely attached yellow-brown to brown, muriform cells (Abdel-Wahab et al. 2010). Moheitospora differs from Cirrenalia in that it has small conidial cells [...]
