Hypocrea bambusae Berk. & Broome, 1873

Parasitic on living inflorescence of bamboo. Sexual morph: Stromata around 0.14 cm diam., 0.06 cm high, solitary, superficial, subglobose, fleshy to coriaceous, black, with around 20 perithecia lining the periphery, with ostioles slightly raised above stroma surface. Stromatic tissue thick, brown to dark brown. Perithecia in vertical section around 100 µm diam., 200 µm high, pyriform, immersed in the periphery layer of stromata. Asci more than 220 µm long, 5–6 µm diam., 8-spored, unitunicate, cylindrical, with a glassy refractive cap around 3 µm from apex to base. Ascospores around 180 µm long, 1–1.5 µm diam., in a single fascicle but not significantly helically coiled, filiform, hyaline, with 9–10 transverse septa, with rounded ends, smooth-walled. Asexual morph: Undetermined.

This taxon has typical morphology of the Clavicipitaceae, which is pyriform perithecia with a gradually tapering upper part and cylindrical asci with a glassy refractive cap. New collections are required and need to be sequenced to clarify its placement.
