Fungalpedia – Note 125 Towyspora   Towyspora Wanasinghe, E.B.G. Jones & K.D. Hyde Citation when using this entry: Gunarathne et al., in prep – The new genera and higher taxa described in 2016. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. The monotypic genus Towyspora was introduced by Li et al., (2016) to accommodate Towyspora aestuari based on phylogeny and morphology. The genus name is derived from the river Towy, Wales, in which the specimen was found. Towyspora is classified in Lentitheciaceae, Pleosporales, Dothideomycetes, Ascomycota (Li et al. 2016). Towyspora aestuari is saprobic on Phragmites communis (Poaceae); an aquatic shrub, and has semi-immersed to immersed, stromatic and pycnidial conidiomata. In the phylogenetic analysis based on ITS, SSU, LSU, and Tef sequence data, T. aestuari formed a separate clade from Setoseptoria with high bootstrap support. Towyspora is similar to Setoseptoria in having subcylindrical, hyaline conidiogenous [...]

Fungalpedia - Note 41 Trichocybe   Trichocybe Vizzini Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep) Index Fungorum, , MycoBank, GenBank, Fig 1-2.  The non-monophyletic nature of the genus Clitocybe (Fr.) Staude was revealed based on the molecular studies by Moncalvo et al. (2002) and Matheny et al. (2006). Later, the combined study of morphology and phylogeny (LSU and 5.8S-rDNA) showed that Clitocybe puberula is not closely linked to C. nebularis (the type species) or to any other extant species of Clitocybe (Vizzini et al. 2010). The systematic position of Clitocybe puberula was always dubious based on the works of Huijsman (1971), and Kuyper (1983). Thus, the genus Trichocybe was erected to accommodate this species and typified by Trichocybe puberula (Synonym: Clitocybe puberula Kuyper) under the family Tricholomataceae (Vizzini et al. 2010). Trichocybe puberula is a fairly rare species, usually found in northwestern Europe (Vizzini [...]

Fungalpedia – Note 335, Triporicellaesporites (Fossil fungi)   Triporicellaesporites P. Ke & Z.Y. Shi  Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Fungi Incertae sedis, Staurosporae. The fossil genus Triporicellaesporites was instituted by Ke & Shi (1978) from the Eocene-Oligocene (55.8–23 mya) sediments of Panshan, Liaoning Province, Coastal region of Bohai, China. The genus includes triangular-lenticular spores having triangular outline in polar view. Spores are triporate, with prominent pores situated at the corners of the triangle, which might be vestibulate. Spores are multicellular, cells in triangulate [triaxial?] arrangement. Spore wall is of medium thickness, surface psilate or provided with granulate to indistinct finely reticulate sculpturing. Kalgutkar & Jansonius (2000) emended the generic diagnosis as follows: “Pluricellate fungal spores with triangular to inverted V-shaped outline, with a central [...]

Fungalpedia – Note 288, Tropohalonectria   Tropohalonectria R.H. Perera, E.B.G. Jones & 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: Ceratosphaeriaceae, Magnaporthales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Perera et al. (2016) introduced monotypic genus Tropohalonectria to accommodate Pseudohalonectria suthepensis, which clustered distantly from Pseudohalonectria, based on LSU-SSU-tef1α phylogeny and morphological differences. Tropohalonectria is characterized by dark brown, globose to ellipsoidal ascomata with a neck. They occur solitary or in small clusters and, are immersed beneath raised host surface. The peridium is pale brown and comprises of 2–3 strata. The inner layer consists of compressed angular cells while cells of outer layer are less distinct and fuse with host tissue. Paraphyses are numerous, filamentous, septate, unbranched, hyaline, tapered and [...]

Fungalpedia – Note 501, Tubeufiales    Tubeufiales Boonmee & K.D. Hyde Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomata. Index Fungorum, Facesoffungi; MycoBank, GenBank, Fig. 1  Classification: Tubeufiales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi Tubeufiales was introduced by Boonmee et al. (2014) to accommodate the type family Tubeufiaceae, based on molecular phylogenetic studies (Lu et al. 2018). Tubeufiaceae was established in Pleosporales by Barr (1979) based on the generic type Tubeufia. Later, Tubeufiaceae was accommodated in a new order Tubeufiales by Boonmee et al. (2014) based on morphology combined with LSU, SSU, and TEF1 sequence analysis. Currently, Tubeufiales accommodates three families, namely Bezerromycetaceae, Tubeufiaceae, and Wiesneriomycetaceae. The most prominent characteristic of Tubeufiales is the asexual morph of Tubeufiaceae, which has three main types: helicosporous, chlamydosporous, and phragmosporous (Lu et al. 2018). Type family: Tubeufiaceae M.E. Barr Other accepted species: Species Fungorum – search Tubeufiales [...]

Fungalpedia – Note 327, Tumenectria   Tumenectria Salgado & Rossma  Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Nectriaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi             Salgado-Salazar et al. (2016) introduced Tumenectria to accommodate Nectria laetidisca, which exhibits little resemblance to Nectria. Furthermore, N. laetidisca formed a monophyletic sister group to Campylocarpon and Rugonectria in an analysis of the concatenated act, ITS, LSU, rpb1, rpb2, SSU, tef, and tub2 loci (Salgado-Salazar et al. 2016). The genus is characterized by astromatic ascomata that arise alone or in multiples from a single point, and are easily detached from the substratum. They are 370–580 × 300–415 μm in size, globose, and have smooth perithecial walls. The orange-to-scarlet ascomata turned red in [...]

Fungalpedia - Note 38 Ulurua   Ulurua Trappe, Claridge & Kovács Citation if using this entry: Fallahi et al. (2023) New genera in 2010-2011. Mycosphere (in prep) Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1 Trappe et al. (2010) proposed Ulurua as a new monotypic truffle genus in Pezizaceae (Pezizales). The type species Ulurua nonparaphysata Trappe, Claridge & Kovács occurs in Uluru Kata Tjuka National Park and surroundings, Australia. The lack of paraphyses in the hymenium of this desert truffle is characteristic among truffles that form hymenial palisades. The phylogenetic analysis based on nrDNA LSU sequence data showed a close relationship between Ulurua and Mycoclelandia, but the lack of paraphyses and the presence of the ornamented spores introduced a new genus in Pezizaceae (Trappe et al. 2010). Ulurua nonparaphysata develops furrowed, globose to turbinate ascomata. The peridium is tomentose and brown. Gleba with labyrinthine veins is partly empty to be filled [...]

Fungalpedia - Note 29 Uzbekistanica Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press) Uzbekistanica Wanas., Gafforov & K.D. Hyde             Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Uzbekistanica was introduced by Wanasinghe et al. (2018) based on morphology and phylogeny (ITS, LSU, SSU, tef and rpb2). Uzbekistanica belongs to Melanommataceae (Pleosporales, Dothideomycetes), which has a wide distribution in temperate and subtropical regions in various woody plants found in terrestrial, marine, or freshwater habitats. The melanommataceous genera Marjia, Gemmamyces, Melanocucurbitaria, Muriformistrickeria, Pseudostrickeria, and Praetumpfia are morphologically similar to Uzbekistanica in having muriform ascospores. Uzbekistanica species have been isolated from Uzbekistan, Russia and Iran as pathogens and saprobes on Rosa hissarica, Juglans regia, and Prunus armeniaca(Wanasinghe et al. 2018, Hongsanan et al. 2020, Bagherabadi & Zafari 2021). Both sexual and [...]

Fungalpedia - Note 261, Valdensia   Valdensia Peyronel. Citation when using this entry: Aumentado et al. 2024 (in prep) – Fungalpedia, plant pathogens.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1. Classsification: Sclerotiniaceae, Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi Valdensia was introduced by Peyronel (1923) and typified with Valdensia heterodoxa. Valdensia (asexual) and Valdensinia (sexual) have the same type of species and are generic synonyms; however, including Asterobolous, Johnston et al. (2014) proposed to conserve the former over the latter. This monotypic genus is characterised by its star-shaped conidia (stauroconidia), which are stellate, thick-walled, range from hyaline to pale brown, and are typically surrounded by a whorl of four or five appendages (Nekoduka et al. 2012) to three to six (Abbasi et al. 2023). Conidia have a single row of 8–10 closely spaced, thin-walled, transverse swellings on the proximal sections of the upper surfaces of the appendages, whereas the distal portion of the appendages is [...]

Fungalpedia – Note 308, Varicosporellopsis   Varicosporellopsis Lechat & J. Fourn. Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Nectriaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Lechat & Fournier (2016) introduced Varicosporellopsis to accommodate single species, Varicosporellopsis aquatilis, based on LSU and ITS sequence data. Subsequently another two species were added to the genus (Crous et al. 2021; Dou et al. 2023). Varicosporellopsis species were isolated from submerged wood collected in freshwater and sludge in water reservoir (Lechat & Fournier 2016; Crous et al. 2021). The terricolous species Varicosporellopsis shangrilaensis, which was found in a cold, high-altitude, terrestrial environment, occurred in rhizosphere soil (Dou et al. 2023). The sexual morph of the genus is characterized by astromatic, solitary ascomata that [...]
