Farasanispora
Farasanispora Abdel-Wahab, Bahkali & E.B.G. Jones, in Li et al., Fungal Diversity 78: 10.1007/s13225-016-0366-9, [63] (2016).
Index Fungorum number: IF 9919; Facesoffungi number: FoF 06671, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on decaying wood. Sexual morph: Ascomata immersed to erumpent, sub globose, solitary to gregarious, coriaceous, dark brown to black, ostiolate. Peridium unequal in thickness, comprising two different cell layers, outer layer of brown to hyaline polygonal cells fused with host tissue and thick inner layer composed of several hyaline flattened cells of textura angularis. Peridium less developed at the base, hyaline to light brown cells fused with the host tissue. Hamathecium comprising numerous, septate, branched, filamentous pseudoparaphyses resembling hyphae embedded in a gelatinous matrix, anastomosing above the asci. Asci 8-spored, bitunicate, fissitunicate, cylindrical to clavate, short pedicellate, apically rounded and thickened with an ocular chamber. Ascospores biseriately arranged, constricted at the septa, rugose, hyaline, fusiform,1–3 septate, the septum is sub-median, upper cell longer and wider, slightly curved, guttulate, lacking a mucilaginous sheath. Senescent ascospores are larger, light brown, flattened, distinctly constricted at the middle septum, striate, verruculose, 2–3 septate. Asexual morph: Unknown (adapted from Li et al. 2016 and Devadatha et al. 2018).
Type species: Farasanispora avicenniae Abdel-Wahab, Bahkali & E.B.G. Jones
Notes: Farasanispora is characterised by immersed to erumpent, sub globose, solitary to gregarious, coriaceous ascomata, bitunicate, fissitunicate, cylindrical to clavate, short pedicellate asci and hyaline, fusiform, 1–3 septate ascospores without a mucilaginous sheath. In the multigene phylogenetic analyses of Devadatha et al. (2018) based on combined LSU, SSU, TEF1, ITS and RPB2 sequence data, F. avicenniae (NFCCI-4220) formed a sister clade to Trematosphaeriaceae and Morosphaeriaceae and was distantly related to Massarinaceae. Farasanispora did not group with any known family in Dothideomycetes and was referred to Pleosporales, genera incertae sedis. More collections and DNA sequence data are needed to confirm the systematic position of Farasanispora. Molecular markers available for Farasanispora include ITS, LSU, SSU, TEF1 and RPB2.
