Click to collapse Descriptions Info

Stroma discoidal, sometimes pulvinate 2.5-7 mm diameter, 1-2 mm thick, scattered or caespitose, ochraceous, punctate with dark ostioles, margins free often undulate, thickened. Stroma pseudoparenchymatous outer tissue hyaline, loosely aggregated 5-7.5 µ diameter, thin walled. Perithecia oval sometimes globose 0.5 x 0.2-0.5 mm crowded in a superficial pigmented zone, ostiole 50-70 µ, papillate; perithecial wall 5-10 µ thick, pigmented yellow. Asci cylindrical 60-100 µ x 4 µ, 16 part-spores uniseriately arranged. Part-spores globose or cuboid, 3.5-4 µ, or oval 5-5.5 x 3.5-4 µ, hyaline, thin walled, echinulate.
Stroma discoidale interdum pulvinatum 2.5-7 mm diam., 1-2 mm crassum, sparsum vel caespitosum, ochraceum, punctatum, ostiole fusco, marginibus liberis, undulatis sed densatis, pseudoparenchymatum cellulis exterioribus compactis 5-10 µ diam. leviter tinctis, interioribus hyalinis laxe aggregatis 5-7.5 µ diam., parietibus tenuibus. Perithecia ovalia interdum globosa 0.5 x 0.2-0.5 mm pariete 5-10 µ crasso, ostiolo 50-70 µ papillato. Asci cylindrici 60-120 µ x 4 µ, 16 sporis divisis paraphysibus evanescentibus. Sporae divisae globosae vel cuboides 3.5-4 µ, vel ovales 5-5.5 x 3.5-4 µ hyalinae, parietibus tenuibus, echinulatae.
Under this species are included those collections misdetermined as H. colensoi by Dingley (1952a). This large fleshy species differs from most Hypocreas in that the thickened margins of this stroma are free, undulate and usually without imbedded perithecia. Unlike those of H. schweinitzii (Fr.) Sacc. and H. cerebriformis Berk. & Br. spores are hyaline.
Type collection: Taranaki, Mt. Egmont, April 1946, J.M.D. (6272).
