Hygrophoropsis is a genus of gilled fungi in the family Hygrophoropsidaceae. It was circumscribed in 1888 to contain the type species, H. aurantiaca, a widespread fungus that, based on its appearance, has been affiliated with Cantharellus, , and Paxillus. Modern molecular phylogenetic analysis shows that the genus belongs to the suborder Coniophorineae of the order Boletales.
There are 16 accepted species of Hygrophoropsis, found in both the Northern and Southern Hemispheres. Hygrophoropsis is a saprophytic genus that causes brown rot in the wood it colonises. The fruit bodies grow on the ground in woodlands, on moss, peat, and on woodchips. They are convex to infundibuliform (funnel-shaped) and have decurrent, forked brightly colored gills. The spores are dextrinoid, meaning that they stain reddish-brown in Melzer's reagent. Because H. aurantiaca has orange gills, it has been mistaken for a chanterelle, and hence it has been called a false chanterelle.
Hygrophoropsis was originally circumscribed in 1888 by German mycologist Joseph Schröter as a subgenus of Cantharellus. It contained a single species, the widespread H. aurantiaca,commonly known as the false chanterelle. German naturalist Bernhard Studer-Steinhäuslin concluded in 1900 that the fungus was more appropriately placed in the genus , based on its white spores, decurrent gills, and lack of a ring on the stipe. This classification was adopted in the early writings of influential mycologist Rolf Singer, who in 1943 proposed that Hygrophoropsis should be a subgenus of Clitocybe.
