Hohenbuehelia is a pleurotoid genus of agaric fungi characterized by gelatinous-sheathed bowling-pin-shaped cystidia, on conidia, basidiospore germ tubes, and mycelium that adhere to and capture nematodes. The fruitbodies bear thick-walled cystidia (metuloids) in the hymenium along the gill sides and that differentiate the genus from Pleurotus in the Pleurotaceae family. The genus has a widespread distribution and contains about 50 species.
