Fungalpedia - Note 390, Soosiella   Soosiella Hujslová & M. Kolařík Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Hyphodiscaceae, Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi. The multigene phylogenetic analysis of ribosomal DNA sequences (ITS region, SSU, LSU) belonging to different phylogenetic lineages in Sordariomycetes and Leotiomycetes (Pezizomycotina, Ascomycota) by Hujslová et al. (2014) revealed that Soosiella typified with Soosiella minima, the only species belonging to the genus. On acidic medium, Soosiella minima produces Mycelium sterile, 2.5–4.0 μm wide, sparsely branched, irregularly granular. The phylogenetic placement of Soosiella is doubtful based on ITS, SSU, and LSU phylogenies. However, the phenotypic characteristics of acidotolerance support this genus. Soosiella was introduced based on the asexual morph in Leotiomycetes (Pezizomycotina, Ascomycota), but the sexual morph is unknown. Soosiella is [...]

Fungalpedia - Note 27 Speleostelium   Citation: Bhunjun et al. 2023 – Fungalpedia, genera described in 2018, Mycosphere (in press)   Speleostelium S. Baldauf, S. Sheikh & Thulin Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Speleostelium is classified in Raperosteliaceae and comprises a single species, Speleostelium caveatum which is the type species (Sheikh et al. 2018). Speleostelium is morphologically similar to Tieghemostelium, Hagiwaraea and Raperostelium, but the genus is different from other genera based on small subunit rRNA gene (Sheikh et al. 2018). The sorocarps have hyaline, long, delicate stalks. The spores are ellipsoid, hyaline and granuled. The myxamoebae prey upon cells of other dictyostelids and prevent them from fruiting. Type species: Speleostelium caveatum (Waddell et al.) S. Baldauf, S. Sheikh & Thulin Basionym: Dictyostelium caveatum D.R. Waddell, Raper & A.W. Rahn     Fig 1. [...]

Fungalpedia– Note 6 Spencermartinsia   Spencermartinsia A.J.L. Phillips, A. Alves & Crous   Citation if using this entry: Noorabadi MT & Hyde KD (2023) New genera in 2008. Mycosphere (in press)  Index Fungorum Identifier 511762, Facesoffungi, MycoBank, GenBank, Fig 1 Spencermartinsia was introduced by Phillips et al. (2008), and this genus was typified by Spencermartinsia viticola Phillips, Alves & Crous (= Botryosphaeria viticola Phillips & Luque) that originally was isolated from pruned canes of Vitis vinifera in Spain. Phylogenetic analysis of combined SSU, LSU, ITS, β-tubulin and EF1-α sequences placed this genus in Botryosphaeriaceae, Botryosphaeriales, Dothideomycetes. Phylogenetic results revealed that Spencermartinsia formed a distinct clade from other allied genera such as Botryosphaeria and Dothiorella in Botryosphaeriaceae. The main morphological characteristics of this genus are brown, 2-celled ascospores with an apiculus at either end (Phillips et al. 2008).       Fig 1.

Fungalpedia - Note 139 Sphaerobolus   Sphaerobolus Tode Citation if using this entry: Bera et al. (in prep) Basidiomycota. Mycosphere Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Basidiomycota, Agaricomycetes, Geastrales, Geastraceae The name “Sphaerobolus” signifies the ability of the fungus to eject glebae to a noteworthy distance (Geml et al. 2005a). The direction to eject the gleba is always towards the brightest source of light in the environment (Walker 1927, Buller 1933). This unique genus was first described by Pier Antonio Micheli in 1729 as Carpobolus P. Micheli but later Tode established it as Sphaerobolus (Vasava et al. 2021). The production of basidiospores in an enclosed structure and passive spore discharge mechanism make the genus a member of the class Gasteromycetes (Hibbett et al. 2007). However, the systematic position of Sphaerobolus has been quite ambivalent. The genus has been periodically [...]

Fungalpedia – Note 349, Sphagnurus   Sphagnurus Redhead & V. Hofst. Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Parasites. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig.1            Classification: Lyophyllaceae, Agaricales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi The type species of Sphagnurus is Sphagnurus paluster, a fungus within the Lyophyllaceae family known to parasitize Sphagnum moss. This genus was firstly described by Peck (1873). Commonly referred to as Sphagnum greyling, this fungus is found in peat bogs, and its cap turns gray as it matures and dries. When young, Sphagnurus paluster may appear white and pruinose, and remains unstained and unbruised when crushed. The flesh is thin, soft, and watery. Initially conical or bell-shaped, when young, the cap expands to a flat form with a distinct umbo as it ages. It is smooth, striate, hygrophanous, typically olive-brown [...]

Fungalpedia – Note 241, Stauromyca (Fossil Fungi)   Stauromyca R. Kar, Mand. & R.K. Kar. Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Incertae sedis, Fossil Ascomycota, Fungi. The monotypic fossil genus Stauromyca was described by Kar et al. (2010) in the Bhuban Formation (Miocene, 23–5 mya) of Tlangsam, Mizoram, India. This genus includes hyphomycetaceous fungi with long, tubular, septate, and straight-to-bent conidiophores. Conidia are solitary, globular-triangular, folded, and generally four-armed. The basal cells are septate and swollen at the base. Arms are variable in length, mostly nonseptate, tubular, and light brown. The wall is less than 1 μm thick, laevigate. Type species: Stauromyca radiata Kar et al. 2010.     Figure 59 – Stauromyca radiata. Scale bar = 10 μm. Redrawn from Kar et al. [...]

Fungalpedia - Note 135 Stereum   Stereum Hill ex Pers.  Citation if using this entry: Bera et al. (in prep) Basidiomycota. Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Basidiomycota, Agaricomycetes, Russulales, Stereaceae The name “Stereum” was first used in a generic sense by John Hill in 1751 (Chamuris 1988). From 1955 to 1968, emphasizing the micro-morphological characters, Stereum was defined in a more restricted manner to only the closely related taxa of the type species,  S. hirsutum (Willd.) Pers. (Boidin 1958, Pouzar 1959, Parmasto 1968, Chamuris 1988, Eicker & Louw 1998). The generic characteristic features that delimited the genus are the stipitate to effuso-reflexed, or dirnidiate or resupinate habit, presence of encrusted cystidia (gloeocystidia or sulfocystidia), and clamp connections in both basidia and hyphae (Eicker & Louw 1998). Thus, after narrowing the concept of Stereum, the genus [...]

Fungalpedia - Note 499, Strangosporaceae   Strangosporaceae S. Stenroos, Miądl. & Lutzoni Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Lichenicolous fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Strangosporaceae, Incertae sedis, Incertae sedis, Incertae sedis, Pezizomycotina, Ascomycota, Fungi. Strangosporaceae, a new family, was introduced by Miadlikowska et al. (2014) to reclassify the Strangospora, based on phylogenetic analysis. Strangosporaceae consists of a single genus, Strangospora, with S. pinicola as the type species, comprising epiphytic, epixylic or bryophylous lichens with crustose and often poorly (Miadlikowska et al. 2014). Strangosporaceae is characterized by convex, biatorine, exciple poorly developed apothecia; slender, essentially unbranched paraphyses; clavate, with gelatinous outer layer, a strongly thickened I+ blue wall and apical dome asci; aseptate, globose ascospores (Körber 1860, Miadlikowska et al. 2014, Morse & Lendemer 2019). Type genus: Strangospora Körb. [...]

Fungalpedia – Note 228, Striadiporites (Fossil Fungi)   Striadiporites Varma & Rawat. Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1             Classification: Fossil Fungi, incertae sedis. The monotypic fossil genus, Striadiporites, was described by Varma & Rawat (1963) from the Late Oligocene-Early Miocene (28–18 mya) sediments of western and eastern India, including oil exploration areas in West Bengal and Assam. Varma & Rawat (1963) give the following short diagnosis “Diporate grains with striated exine”. Elsik & Jansonius (1974) published an elaborate generic diagnosis to include fungal spores of oval to fusiform ambitus with longitudinal ribbed to broadly reticulate ornament. Two pores, one at each end of the spore, are present along the long axis. Unicellate with no septa, except occasionally, a very [...]

  Fungalpedia – Note 324, Striatibotrys   Striatibotrys L. Lombard & Crous Citation when using this entry: Perera et al. 2024 (in prep.) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Stachybotryaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi             Lombard et al. (2016) erected Striatibotrys to place a group of stachybotrys-like fungi that characterised by longitudinally striate conidia. They clustered distantly from Stachybotrys s. str. in the analysis of cmdA, ITS, rpb2, and tub2 (Lombard et al. 2016). Striatibotrys species produce astromatic, perithecial ascomata that are scattered, subglobose to obpyriform, orange and do not change colour in KOH. The ascomata have a rounded papillate apex with setae that protrude at the periderm surface, otherwise, they are completely submerged in the host tissue. Except for the ostiolar region, the [...]
