Morphology. The fruit-bodies producing asci and ascospores; simple, or compound (often tufted); erect-elongate, unbranched; clavate (the heads often each with a longitudinal groove); clustered to solitary; stipitate; small to medium sized; 2–5(–6) cm high; very dark olive, or green, or blackish; apothecial; producing asci and spores on an exposed hymenium; stromata absent. Asci inoperculate; the asci thin walled. The walls of the asci with J+ or J- pore. The ascospores elongate (often), or ellipsoid; brown.
The hyphae without clamp connections. The hyphal walls lamellate, double layered, with both layers electron dense.
Ecology. The fruit-bodies borne on the ground. Found in broad-leaved woodland and in mixed woodland.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
