Helotium pezizoideum Cooke @ Phillips in Grevillea 19, 72 (March 1891).

Apothecia scattered, superficial; disc slightly concave, ochraceous, up to 2 mm. across; receptacle slightly paler, shallow cupshaped, smooth, with a short, stout stalk, usually strigose with white hairs towards the base. Excipulum of slightly undulating parallel hyphae, 5-6 µm wide, lying at a moderate angle to the surface. Asci cylindric-clavate, 70-90 x 6-7 µm, 8-spored, the pore only faintly blued by Melzer's reagent; ascospores biseriate, cylindric-clavate, tapering below, straight or slightly curved, 10-14 x 2.5-3 µm. Paraphyses cylindrical, not enlarged at the tips, 2 µm thick, with granular contents. On decorticated wood.

This is clearly a member of the H. calyculus-H. conscripturn series but is probably worth maintaining as a distinct species because of its narrower ascospores and rather shorter asci.
