Delitschia winteri  

Anamorph: unknown.
Teleomorph: Stromata absent. Ascomata 300-450µm diam, ± globose, dark brown, ± glabrous, with a strongly papillate to cylindrical neck. Peridium composed of several layers of fairly thick-walled textura angularis with cells to 18µm diam. Interascal tissue composed of copious trabeculate pseudoparaphyses. Asci 345-385 x 39-46 µm, cylindrical, short-stalked, the apex obtuse, 8-spored. Ascospores arranged obliquely uniseriately, 56-61.5 x 28-31 µm, widely cylindric-fusiform, the ends obtuse to acute, very thick-walled and almost opaque, dark brown, hardly constricted at the thick median transverse septum, with two inconspicuous narrow longitudinal germ slits in each spore, opposite each other and at 90° to those in the other cell, with a well-developed gelatinous sheath that may degenerate after discharge.

A collection from the New Forest (Hants) on horse dung (IMI 82177) has rather larger ascospores, but the specimen is inadequate for proper characterization.
