Fungalpedia – Note 108 Oxydothis   Oxydothis Penz. & Sacc. Citation when using this entry: Manawasinghe et al., in prep – Fungalpedia, palm fungi, genera, and terminology. Mycosphere. Index Fungorum: IF3661, Facesoffungi: FoF05091, MycoBank 3661, GenBank 63191, Fig 1. Oxydothis was introduced by Penzig & Saccardo (1897) from Cibodas, Java, Indonesia. Oxydothis grisea (= O. nigricans) is the type species (Penzig & Saccardo 1897). These species are characterized by ascomatal orientation, which is often horizontal, unitunicate asci which are fusiform or filiform with a J+ (rarely J-), wedge-shaped or discoid, subapical ring and ascospores which are 1-septate with spine-like or rounded ends (Hyde 1994). Following Oxydothis taxa develop two types of ascomata (Fröhlich & Hyde 2000), The first type develops on the host surface singly or in clusters. They are dark and ellipsoidal raised areas on the host surface [...]

Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1             Classification: Hypoxylaceae, Xylariales, Sordariomycetes, Fossil Ascomycota.  Ramanujam & Srisailam (1980) instituted the fossil genus, Palaeoamphisphaerella, from the Miocene (23–5 mya) sediments of Palayangadi, Kannur District, and Cheruvattur (southern side of Karingottu River), Kasaragod District, Kerala, India. This genus is characterized by brownish to dark brown, aseptate, elliptical, oblong, or somewhat rhomboidal spores with rounded ends. The pores were equatorial and equidistant. The surface was scanned at a psilate-to-scan rate.  According to Ramanujam & Srisailam (1980), equatorially disposed pores are a characteristic feature of this genus. The fossil spores exhibited a remarkable resemblance to the ascospores of the extant Amphisphaerella Henn. (Current name: Rosellinia [...]

Fungalpedia – Note 406, Palaeoendogone   Palaeoendogone Strullu-Derr. & Strullu Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Mucoromycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Incertae sedis, Incertae sedis, Incertae sedis, Incertae sedis, Mucoromycotina, Mucoromycota, Fungi. Octosporopsis was introduced by Strullu-Derrien et al. (2014) as a monotypic genus within Mucoromycotina to accommodate the type species Palaeoendogone gwynne-vaughaniae (basionymized with Humaria nicolai), based on morphology.  Currently, only one species is accepted in this genus, which is endophytic in the corm of Horneophyton lignieri (fossilized plants) in Scotland (Strullu-Derrien et al. 2014). This genus is mainly characterized by aseptate intercellular branched thin-walled and intercellular thicker-walled hyphae present in the corm of the plant, which form intracellular coil-like structures. (Strullu-Derrien et al. 2014). Palaeoendogone gwynne-vaughaniae is similar to fungus no. 3 in the plant Nothia aphylla described by Krings et al. (2007a), which closely resembles Glomites rhyniensis [...]

Fungalpedia – Note 430, Palaeospora   Palaeospora Oehl, Palenz., Sánchez-Castro & G.A. Silvav Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Glomeromycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Archaeosporaceae, Archaeosporales, Incertae sedis, Glomeromycetes, Glomeromycotina, Glomeromycota, Fungi. In a survey of Switzerland's natural and agricultural sites, Oehl et al. (2015) introduced a new genus Palaeospora with Palaeospora spainiae as the type species based on morphological and molecular analyses (SSU, ITS, LSU). Palaeospora differs from Archaeospora and Otospora owing to their triple-walled spores. Furthermore, the genus is distinguishable from Acaulospora due to the lack of beads on the inner wall and varies from Ambispora due to the lack of a bi-walled pedicel as ramification from the hyphal saccule neck (Oehl et al. 2015).  In 2019, Schüßler & Walker (2019) analyzed all available Archaeospora sequence [...]

Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Palmiascoma is a monotypic genus described by Phookamsak & K.D. Hyde (Liu et al. 2015) with P. gregariascomum as the type species. Palmiascoma are basically saprobic and grow on bamboo culms. The genus has corticolous, coriaceous, gregarious uni- or multi-loculate perithecia, which are scattered, immersed to erumpent, ostiolar necks are papillate, and the peridium is composed of textura subglobosa and textura angularis cell layers. Asci are bitunicate with long pedicels. Ascospores are brown, didymosporous, apical cells are wider and more acute than basal cells. The anamorphs of Palmiascoma produce pycnidial conidiomata that contain one-celled conidia on artificial agar media. The present collection [...]
