Currently, about 90 species are included in this genus (http://​www.​mycobank.​org). Phylogenetic study The phylogenetic analysis based on ITS-nLSU rDNA, mtSSU rDNA and ß-tubulin sequences indicated that Sporormiella nested in Preussia, and a Sporormiella–Preussia

complex is formed (Kruys and Wedin 2009). Thus, Sporormiella was assigned under Preussia (Kruys and Wedin 2009). Concluding remarks It is clear that the presence or absence of an ostiole cannot distinguish Sporormiella from Preussia according to the findings of Guarro et al. (1997a, b) and Kruys and Wedin (2009). Thus, Sporormiella should be treated as selleck inhibitor a synonym of Preussia (Kruys and Wedin 2009). Spororminula Arx & Aa, Trans. Br. Mycol. Soc. 89: 117 (1987). (Sporormiaceae) Current name: Preussia Fuckel, Hedwigia 6: 175 (1867) [1869–70]. Generic description Habitat terrestrial, saprobic (coprophilous). Ascomata small to medium, solitary, scattered, immersed to erumpent, globose, subglobose, to ovate, black, membraneous, papillate, ostiolate. Peridium thin, membraneous, composed of several layers of heavily pigmented, elongate cells of textura angularis. Hamathecium of dense trabeculate, aseptate, decomposing pseudoparaphyses. Asci bitunicate, broadly cylindro-clavate with a narrow furcated pedicel. Ascospores cylindrical to cylindro-clavate, with round ends, brown, multi-septate,

easily breaking into partspores.
