Pseudotrichia minor  

Anamorph: not known.
Teleomorph: ascostromata perithecial, 220-300 µm diam. and 250-370 µm high, in clusters of 6-15, initially immersed just beneath the ectostroma surface of the host fungus but sometimes becoming almost superficial as the host tissue degrades, the basal part ± globose with a shortly papillate to pyriform neck 70-100 µm diam., black, smooth-walled. Peridium 30-40 µm thick, consisting of several layers of brown cells 6-10 x 3-5 µm in size, the cells of the neck region tending to be smaller and more strongly melanized. Interascal tissue composed of copious trabeculate pseudoparaphyses ca 1 µm diam., the ostiole lined with periphyses. Asci 80-95 x 9-12 µm, narrowly clavate with a long tapering stalk, the apex rounded, thick-walled and fissitunicate with a clear ocular chamber, 8-spored. Ascospores biseriately arranged, 16.5-20 (-24) x 4.5-6 µm, fusiform, the apex acute and the base obtuse, straight or somewhat inaequilateral, strongly constricted at the ± median primary septum, usually but tardily developing a secondary septum in each cell, the cell above the primary septum strongly inflated, hyaline, smooth-walled, apparently without a gelatinous sheath or appendages.
