The species is peculiar in its color and habitat. In the dried specimen the gills have assumed a brown color with no ochraceous tint. Mr. McIlvaine remarks that it is an edible species, dries well, and is excellent when cooked. Its relationship is with F. anomala Pk., but it is a larger plant with darker color and a different habitat. _Peck_, Bull. Torr. Bot. Club, Vol. 26, F. 1899. It grows on partly _burned_ anthracite coal, not _buried_, as printed in the Torrey Bulletin. The mycelium completely involves the pieces of coal, holding them tightly in its meshes. Patches of it were strictly limited to the size of the ash-pile containing the partly burned coal. Quite fifty were found. As stated, it is edible, and it is of remarkably fine substance for a Flammula. LU´BRICI. Pileus viscid, etc. =F. edu´lis= Pk.—eatable. =Pileus= fleshy, convex, obtuse, glabrous, moist, brown, grayish-brown or yellowish-brown, sometimes rimose. =Flesh= whitish. =Lamellæ= rather broad, close, decurrent, bright tan color, becoming brownish-rusty. =Stems= cespitose, equal, stuffed or hollow, brown. =Spores= subelliptical, 13×5–6µ. =Pileus= 2–3 in. broad. =Stem= 2–3 in. long, 3–6 lines thick. Grassy ground, along pavements, in gutters and by the side of wooden frames of hotbeds. Haddonfield, N.J. October. _C. McIlvaine._ The collector of this species informs me that the flavor of the fresh plant is slightly bitter, but that this disappears in cooking and the fungus furnishes a very good and tender article of food. Successive crops continued to appear for a month. In the dried specimens the stem is striate. _Peck_, Bull. Torr. Bot. Club, Vol. 24, No. 3. This new species appears annually in the same place. I have not found it elsewhere. It is meaty and excellent. UDI. Pileus smooth, not viscid; veil fragmentary, etc. (Plate LXXVI_b_. [Illustration: FLAMMULA ALNICOLA. Two-thirds natural size. ] =F. alni´cola= Fr.—_alnus_, alder; _colo_, to inhabit. =Pileus= 2–3 in. broad, _yellow_, at length becoming rust-color and sometimes green, fleshy, convex then flattened, obtuse, slimy when moist, but not truly viscous, at the first superficially fibrillose toward the margin. =Flesh= not very compact, of the same color as the pileus. =Stem= 2–3 in. and more long, ½ in. thick, _stuffed then hollow_, attenuato-rooted, commonly curved-flexuous, _fibrillose_, at first yellow, then becoming rust-color. =Veil= _manifest_, sometimes fibrillose, sometimes woven into a spider-web veil. =Gills= somewhat adnate, broad, plane, at first _dingy-pallid_ or yellowish-pallid, at length together with the plentiful spores rust-colored.
