PLEUROTUS Fr. 
(Gr., pleuron, a side; o«s, an ear.) 
“Pileus fleshy or submombranaceous ; excentric, dimidiate or resupinate. Stem 
exeentric, lateral or wanting; with or without a ring. Gills sinuate, adnate, 
decurrent or radiating from a central point. Spores white, rarely pink, yellowish, 
lilac, or dingy; elliptical, globose, subglobose, pip-shaped, oblong elliptical, 
cylindrical or reniform; smooth, granular, verrucose or echinulate; continuous. 
Cystidia present or absent'. Growing on wood, more rarely on the ground or 
on dung.” — Rea. 
The species are characterised by the. white spores, rarely slightly coloured, and 
a stem which is excentric, lateral or may even be absent and which is fleshy and 
continuous with the pileus. The gills vary but are often decurrent; in some of 
the very small species they may radiate from a central point. Some of the 
species are amongst the largest of our agarics and others arc only a few milli- 
metres in diameter. PleuroUis Ucmpas, our largest one, is luminescent and is 
quite common at the bases of Euealypts. The colour of the larger species is 
usually whitish with tints of brown, sometimes in the case of P. larnpas with 
shades of lilac, grey and yellow brown. Many of the smaller species are greyish. 
In some, the upper layer of the pileus is subgelatinous. They nearly all grow
