Connopus R.H. Petersen, in Hughes et al., Mycologia 102(6): 1467 (2010)
Diagnosis: Basidiomata connate in small to large numbers, collybioid or mycenoid, often with long stipes. Pileus strongly convex to hemispherical when young, plano-convex by maturity, strongly hygrophanous, smooth, slippery when wet, tan-brown to ruddy brown. Lamellae free to adnexed, seceding early leaving a purplish ring on inner pileus around stipe apex, off-white, close. Stipe ruddy brown to purplish brown, glabrous above, fistulose, developing a white pruina or thin tomentum where protected downward. Flavor and odor negligible. Habitat usually in deep polytrichaceous moss juxtaposed to conifer logs or stumps in temperate to cool forests of the northern hemisphere. Pileipellis a lax trichoderm with occasional, weakly banded, erect terminal cells. Hyphae conspicuously clamped throughout. Basidia four-spored. Pleurocystidia absent. Cheilocystidia occasional to absent, slender-lecythiform. Basidiospores small, ellipsoid to cylindrical, hyaline, thin-walled, inamyloid.
