are channeled at the margin (t. 346. f. c.), finally open and rolled back (t. 581. f. h.), otherwise they are simple and scarcely branched, and, which is singular, in subterranean specimens, as Scopoli affirms, they are the same color as the pileus the cap of the fungus.

Obs. Whether perhaps the LITHODERMOMYCES stone-skin fungus of Batar. p. 62. t. 24. B should be referred here as a resupinate lying flat on the substrate variety with lamellae gills radiating from the center, concerning which the author notes the following: this peculiar fungus was found on tufa rock, baked into a brick arch, without a stalk, attached most tenaciously to the rock. The lower part (pileus) was entirely tomentose covered with matted hairs and ash-colored, the upper part was furrowed (lamellate), the furrows being crowded, slightly shallow, and amethyst in color. The whole substance was a medium between stony and leathery.

LXXIX. AGARICVS. Volva universal veil/cup at the base absent. Pileus fleshy or membranous, entire or halved. Lamellae unequal in length, withering, dry.

† PETRONIA, with a halved pileus.

• Apodes footless/stalkless, with a sessile attached directly without a stalk pileus.

1. Epixylon, gregarious, small, bluish-brown, with a glabrous smooth suborbicular pileus, effuse spread out at the base, attached at the back, with radiating lamellae of the same color.

A. epixylon, small, tender, sessile, halved, scale-shaped, glabrous, leaden-blue above, with broad, rather thick lamellae, at the base
