Sporormiella

Sporormiella Ellis & Everh. N. Amer. Pyren. (Newfield): 136 (1892).

Index Fungorum number: IF 415062; Facesoffungi number: FoF 07980, 58 morphological species (Species Fungorum, 2022), 14 species with molecular data.

Fimicolous. Sexual morph: Perithecia immersed to semi-immersed, scattered or aggregated in small groups, membranaceow to coriaceous, dark brown to black, smooth or covered with hairs in the upper part; neck varying from short papilliform to long cylindrical. Asci eightspored, bitunicate, cylindrical to clavate with short to relatively long stipe. Ascospores three to many-septate, at first hyaline, finally becoming dark brown; septa transverse to oblique; germ slit elongated, extending the entire length of the cell, parallel to diagonal, or transverse to the longitudinal axis of the ascospore; gelatinous sheath hyaline, surrounding each ascospore. Asexual morph: Unknown (adapted from Ahmed & Cain 1972).

Type species: Sporormiella nigropurpurea Ellis & Everh.

Notes: Sporormiella is characterised by depressed-globose, membranaceous perithecia, cylindrical asci and 16–20-celled, rod-shaped ascospores lacking a gelatinous sheath. Sporormiella was synonymized under Preussia based on occurrence on same host and the 16–20 celled, rod-shaped ascospores (Ahmed & Cain 1972, Zhang et al. 2012, Hyde et al. 2013). Ahmed and Cain (1972) provided an updated description of Sporormiella and a key to species of the genus. Since molecular data is lacking for the type species, S. nigropurpurea, Hongsanan et al. (2020a) did not agree with previous studies and maintained Sporormiella as a distinct genus in Sporormiaceae. Sporormiella differs from Preussia in having perithecioid ascomata while Preussia has cleistothecioid ascomata (Cain 1961, Barr 2000). Sporormiella is currently a distinct genus in Sporormiaceae. Molecular markers available for Sporormiella include ITS, LSU, SSU, BTUB, TEF-1 and RPB2.
