Trichoderma citrinoviride

This study corresponds to the sexual or teleomorph stage of the species, known as Hypocrea schweinitzii.

Peridial hyphae hyaline, thin-walled, subglobose to polygonal.

Asci cylindrical, uniseriate, with 8 ascospores that disarticulate within the ascus into 16 part-spores, up to 90 µm long and up to 6 µm wide, with a well-defined inamyloid apical ring in Melzer's reagent, lacking croziers at their base.

Ascospores subglobose to ovoid, smooth- to slightly punctate-walled, hyaline, with only faint greenish intracellular pigment, containing granular internal content.
