Gregarious on a dead hardwood log lying on the ground, Caledonia Gorge Protected Natural Area, New Brunswick (14-08-12/05) and clustered (10) on a mossy dead hardwood log in stand of young Fagus grandifolia and Acer pensylvanicum, Spednic Lake Protected Natural Area, New Brunswick (13-08-17/03), collected by Kendra Driscoll.

Basidiospores white in spore print, 6.4-10.1 X 4.3-6.8 μm, D/d = 1.27-1.65 (average[44]: 8.2 X 5.7 μm, D/d = 1.45), ellipsoidal to dacryoid, amyloid. Cheilocystidia sharply acuminate. The pileipellis is a cutis and gives rise to erect coralloid hyphae. The pruinose material of the stipe is similar to the coralloid elements of the pileus but rather more extensively branched.

Mycena haematopus is common in hardwood forest and is easily recognized by its purplish colours, scalloped pileus margin and stipe exuding a red juice. Microscopically the sharply pointed cheilocystidia are diagnostic.
