Fungalpedia – Note 156, Axisporonites (Fossil Fungi)   Axisporonites Kalgutkar & Janson.  Citation when using this data: Saxena RK & Hyde KD. in prep – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Phragmosporae, Fungi The monotypic fossil genus Axisporonites was established by Kalgutkar & Jansonius (2000) to accommodate Multicellaesporites indicus P. Kumar (1990) described from the Early-Middle Miocene (23–11.6 mya) sediments of Padappakkara, Quilon District, Kerala, South India. The fungal spores are medium-sized, inaperturate, and tricellate, with an overall shape that is more or less elliptical. Two polar cells are smaller, triangular, with dark pigmentation and thicker walled than the large, hyaline central cell. Additionally, the septa are thicker than the wall of the central cell (Saxena & Tripathi 2011). Only one species listed in Index Fungorum (2023) under this genus.  Type species: Axisporonites indicus (P. Kumar) Kalgutkar & Janson.  [...]

Fungalpedia - Note 54 Babjeviella   Babjeviella Kurtzman & M. Suzuki Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep) Index Fungorum, MycoBank, GenBank, Fig 1. The monotypic genus Babjeviella is an ascomycetous yeast in Debaryomycetaceae. It was described as Pichia inositovora by Golubev et al. (1981) and was revised as Babjeviella inositovora based on the phylogenetic analysis of D1/D2 divergent domains of the large subunit (LSU) and the nearly complete small subunit (SSU) rDNA genes by Kurtzman & Suzuki (2010),. The type species of the genus, Babjeviella inositovora, was isolated from high moor peat in the Moscow region of Russia (Golubev et al. 1981). It produces unconjugated asci with one to four hat-shaped ascospores that are released by ascus evanescence. Some bulb-like structures occasionally form on the brims of ascospores. The species’ homo- or heterothallic status has not been confirmed. Colonies are butyrous with a [...]

Fungalpedia - Note 48 Barcheria   Barcheria T. Lebel Citation if using this entry: Bera et al. (2023) Basidiomycota. Mycosphere (in prep)   Index Fungorum, MycoBank, GenBank, Fig. 1 In exploration in the woodlands of Australia, a unique sequestrate mushroom was discovered which has been established as the genus Barcheria T. Lebel (Lebel et al. 2004). The morphological features such as the fragile texture of the basidiomata, the peridium with purplish-brown scales, and cream colour of the gleba changing to pale orange on exposure seemed to be reminiscent of species of Agaricus and Lepiota (Lebel et al. 2004). However, the very reduced form of the basidiomata of Barcheria and the comparative phylogenetic analysis with closely related members of Agaricaceae based on nrLSU sequence data confirmed its identity as a separate genus (Lebel et al. 2004). This [...]

Fungalpedia - Note 484, Barretomyces    Barretomyces Klaubauf, Lebrun & Crous Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Fungal pathogens. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Pyriculariaceae, Magnaporthales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi. Barretomyces was named after Brazilian mycologist Prof. Dr. Robert W. Barreto acknowledges his contribution to mycology and plant pathology (Klaubauf et al. 2014). This monotypic genus consists of only its type species, i.e., Barretomyces calatheae, a popular hyphomycetous pathogen found in amphigenous spots on the leaves of Calathea longifolia in Brazil (Soares et al. 2011, Klaubauf et al. 2014). It was previously described as Pyriculariopsis due to having versicolored conidia bearing slightly paler basal cells and schizolytic secession (Ellis 1971). Later, this genus was created in accordance with multigene (ACT/ITS/RPB1) phylogeny and morphological uniqueness. The morphological difference between [...]

Fungalpedia - Note 248, Barriopsis   Barriopsis A.J.L. Phillips, A. Alves & Crous. Citation when using this entry: Aumentado et al. 2024 (in prep) – Fungalpedia, plant pathogens.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. Classification: Botryosphaeriaceae, Botryosphaeriales, Incertae sedis, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi  Barriopsis was introduced by Phillips et al. (2008), based on morphological characteristics and molecular sequence data. Initially, Barriopsis was classified as Physalospora by Stevens (1926), but it was later transferred to Phaeobotryosphaeria by Petrak & Deighton (1952). Barriopsis considered by Stevens (1926) and Petrak & Deighton (1952) did not have apiculi on its ascospores and were not comparable to Phaeobotryosphaeria, which had small, hyaline apiculi on the ascospores. von Arx & Muller (1954) considered Phaeobotryosphaeria as a synonym of Botryosphaeria. Phillips et al. (2008) initially designated Barriopsis fusca, (N.E. Stevens) A.J.L. Phillips, A. Alves & [...]

Fungalpedia - Note 13 Barromyces Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Barromyces M.J. Powell & Letcher Index Fungorum number, Facesoffungi, MycoBank, GenBank, Fig. 1 Barromyces was introduced by Powell et al. (2018) to accommodate B. tenuis D.J.S. Barr (≡ Gaertneriomyces tenuis D.J.S Barr). It is classified under Spizellomycetaceae, Spizellomycetales, Chytridiomycetes, Chytridiomycota (Powell et al. 2018). Chytrids frequently exhibit morphological plasticity, which can be confusing when the strains are cultivated on various media (Powell & Koch 1977). Barr (1980) established Spizellomycetales D.J.S. Barr as a new order to accommodate soil-inhabiting strains of Phlyctochytrium to accommodate taxa with different zoospore structures. Gaertneriomyces was introduced as one of the genera, however, diverse thallus morphological characters of G. tenuis suggested that it might represent a new genus since it shared morphological characteristics with both Gaertneriomyces and Spizellomyces (Barr 1984) Phylogenetic analysis [...]

Fungalpedia - Note 512, Basidiobolomycetidae   Basidiobolomycetidae P.M. Kirk Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Zygomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Basidiobolaceae, Basidiobolales, Incertae sedis, Incertae sedis, Incertae sedis, Zygomycota, Fungi. Basidiobolomycetidae was identified by Kirk (2014) to accommodate the human pathogenic subcutaneous zygomycosis-causing taxa. Basidiobolomycetidae are typified by Basidiobolus. Basidiobolomycetidae species are characterized by dimorphic sporophores: primary sporophores (a subsporangial vesicle, primary spores globose, solitary, forcibly discharged from the sporophore), secondary sporophores (not basally swollen, and clavate secondary spores with a knob-like adhesive tip and passively released), and spherical, smooth, thick-walled zygospores with two closely appressed beak-like appendages formed in the mycelium (Blackwell & Malloch 1989, Kirk 2014). Type genus: Basidiobolus Eidam Other accepted species: Species Fungorum – search Basidiobolomycetidae   Figure 1 – Basidiobolus ranarum. a-c Tubular extension of conidia apex. d Secondary [...]

Fungalpedia – Note 158, Basidiosporites (Fossil Fungi)   Basidiosporites Elsik. 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 Basidiosporites was instituted by Elsik (1968) from the Rockdale lignite (Palaeocene, 66–56 mya) from a locality 11 km southwest of Rockdale, Milam County, Texas, USA (Salard-Cheboldaeff & Locquin 1980). Basidiosporites is characterized by oval to capsular, monoporate, unicellate, and psilate fungal spores with the pore offset from one apex. No basal attachment area is evident. Shape variables generally elongate in some fashion (Saxena & Tripathi 2011). There are four species included in Index Fungorum (2023) under this genus. Type species: Basidiosporites fournieri Elsik.     Figure 1 – Basidiosporites fournieri. Scale bar = 5 μm. Redrawn from Elsik (1968)   References Elsik WC. 1968 – Palynology [...]
