Berkeley describes specimens of P. dryinus with long stems growing from a hollow in an ash, and Stevenson (p. 167) reports the same condition.
According to the usual descriptions _corticatus_ is given as the larger species, while Fig. 109 of our plant, possessing the typical characters of _dryinus_, is the larger.
According to the descriptions of _P. dryinus_ as given by Persoon, and as followed by Fries and most later writers, the pileus is definitely lateral, and more or less dimidiate, while in _P. corticatus_ Fr., the pileus is entire and the stem rather long and eccentric.
Stevenson suggests (p. 166) that corticatus is perhaps too closely allied to dryinus.
= -- _Pleurotus dryinus_ represents a section of the genus in which the species are provided with a veil when young, but which disappears as the pileus expands.
