Nolanea is a genus of fungi in the order Agaricales, frequently treated as a subgenus of Entoloma. Called pinkgills in English, basidiocarps (fruit bodies) are agaricoid, mostly (but not always) mycenoid (like species of Mycena) with slender stems.[1] All have salmon-pink basidiospores which colour the gills at maturity and are angular (polyhedral) under a microscope. Recent DNA evidence has shown that at least 87 species belong in Nolanea which has a worldwide distribution.[1]
Nolanea was introduced in 1821 by the Swedish mycologist Elias Magnus Fries as a "tribe" of Agaricus comprising slender agarics with bell-shaped caps, hollow stems, and pink spores.[2] In 1871 German mycologist Paul Kummer raised the tribe to genus level.[3] The name has been used by many subsequent mycologists,[4][5][6] but others have preferred to use the name Entoloma sensu lato for all fungi with pink, angular spores, retaining Nolanea as a subgenus.[7]
Recent molecular research, based on cladistic analysis of DNA sequences, has shown that Nolanea, as previously defined, is paraphyletic (an artificial grouping).[8] By excluding some species and adding others, however, Nolanea has been redefined as a monophyletic (natural) grouping.[9][1] In this new sense, Nolanea has been treated either as a subgenus[1] or as a separate genus.[9]
The redefined Nolanea excludes Entoloma rhombisporum and related species, Entoloma ameides and related species, and cuboid-spored species now placed in Entoloma subgenus Cubospora.[1]
