and becomes membranous. The lamellae, relative to the diameter of the pileus, are very broad, ash-colored, leaden-blue, sometimes light reddish. — The color of the fungus, according to Batsch, is blackish-brown-ash. The whole surface is as if frosted, and slightly tomentose at the back. According to the observation of the blessed Sowerby, the color is grayish-green or glaucous covered with a fine bloom, and the pileus is produced into a stalk at the back, by which it often becomes cup-shaped or bell-shaped.

• cocodes, sparse, ash-colored, with a glabrous, convex pileus, at first subresupinate and concave: with an oblique mouth, then truncate-halved, with whitish-ash lamellae. Tab. XXV. Fig. 3. and a.

Found on a dried stem of Pteris aquilina bracken fern and illustrated by Mr. Petit.

Obs. In its manner of growth, and likewise in habit, it has a similarity to A. epixylon, but in the meantime it differs from it by some notes, and is to be examined further.

2. merulinus, gregarious, substipitate having a very short stalk, small, with a halved pileus, attached by a subeffuse base, striate marked with lines, slightly tomentose, with rather broad, distant, white lamellae, simply dichotomous forked in two.

I have very rarely found this pretty species at the base of trunks in a certain garden. In size, it is similar to Ag. applicatus B., but it differs most greatly by having branched lamellae, though they are not fold-shaped; it also has this peculiarity, that the color of the pileus in the same cluster was pale and verdigris-colored.
