Nolanea has been defined as a genus of small gray to brown pink-spored mushrooms that are mostly saprotrophic and grow on the ground. The cap can be conical, convex or umbonate in shape, often with a silky top. The gills have adnexed to adnate attachment (they can also be a little decurrent) and the stalk is fragile and often hollow. The spores are angular and are flesh colored to pink. Nolaneas are well known for being difficult to identify.
Nolanea was introduced as a tribus in Elias Magnus Fries' 1821 work Systema Mycologicum. It is usually considered a subgenus of the large genus Entoloma rather than a genus in its own right. This is reinforced by data produced by the molecular study by Moncalvo in 2002, with species of Nolanea, Leptonia and Inocephalus interspersed with various pinkgill species in a broadly monophyletic entolomatoid group.
Little is known about the edibility of Nolaneas, and some are poisonous.
