The Genus Hohenbuehelia

[ Basidiomycetes > Agaricales > Pleurotaceae ... ]

by Michael Kuo

Members of the genus Hohenbuehelia grow on wood or on woody debris and are usually stem-less, pleurotoid mushrooms. They have white spore prints and often smell and taste mealy. The genus is full of drab colors, from boring shades of beige to dull browns and blacks, which might lead one to call them "Ho-hum-buehelias"--except that other defining features of the genus include stunning "metuloid" cystidia and a "nematophagous" tendency. That last term means that species of Hohenbuehelia eat nematodes--those microscopic worms you may remember from high-school biology. (No, I'm not making this up. Search "hohenbuehelia nematodes" for details and illustrations.)

Identification of Hohenbuehelia species frequently depends, at least in part, on microscopic examination. The keys and descriptions in Thorn (1986) and Thorn and Barron (1986) treat most North American species (along with taxa in a few closely related genera).
