TRICHOLOMA AURANTIA (Schaeff. ex Fr.) Ricken
Figure 169, page 109
PILEUS 1-3 in. broad, convex, becoming expanded, slightly umbonate,
reddish ochraceous to orange-red, rather bright colored, viscid, soon becoming
appressed-scaly, margin floccose, glutinous, inrolled at first, flesh white,
thick on disk, thin on margin, odor farinaceous, lamellae adnexed, close,
white, becoming spotted with rusty brown, a few forked, stipe lYi-'^Vi in.
long, y^-Yi in. thick, equal or narrowed at the base, more or less covered with
rings of scales the same color as the pileus up to an obscure annular zone,
white at apex and between the scales, soHd. spores white, broadly ellipsoid to
ovoid, 4.5-6 X 3-4 m-
Usually gregarious on the ground. Aug.-Oct.
Because of the suggestion of an annulus in this species one might be
incHned to look for it in Armiliaria and some authors have placed it in this
genus. However, the structure of the trama of the lamellae indicates that it is
more closely related to Tricholoma than to Armillaria. It is a rather bright
colored species and can be recognized by the characteristic scahness on the
stipe, the viscid pileus and the lamellae staining brownish. Its edible quahties
are not known.
