Notes: Asci 8-spored, tip blued in Melzer's Iodine.

Ascospores: ellipsoid, with two small guttules, finely warted under oil immersion. 12-13/7-8µm. Immature spores stain in lactophenol cotton blue but older spores in ascus, including wall ornament, unstained. Spores from a spore print show very finely rough with minute and separate warts that faintly stain in lactophenol cotton blue.

Paraphyses: with dark violaceous granular contents, apex slightly swollen and curved to one side.

This is P. praetervisa sensu Dennis with rough spores, which is now called P. violacea.
