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 a synonym
of Preussia (Kruys and Wedin 2009).

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
and released ascospores. d One-celled ascospores. Scale bars: a=
200 μm, b–d=20 μm
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.
Anamorphs reported for genus: none.
