RARE OR NEW BRITISH HYMENOMYCETAL FUNGI. 
By M. C. Cooxe, Esq. 
(Prate III.) 
Acaricus (Pholiota) leochromus, n. s.; pileo carnoso, convexo- 
plano, demum depresso, molli, glabro, non fulgido; stipite solido, sub- 
æquali, levi; annulo persistente ; lamellis rotundato-adnatis, subven- 
tricosis, e pallido cinnamomeis. late 
ileus 2-3 inches, at first convex, then plane, and ultimately de- 
pressed, soft, smooth, but not shining, bright tawny, paler (whitish) at 
the margin, generally rivulose from the cracking of the cuticle. Stem 
3-4 inches, slender, solid, fibrous, internally umber-brown at the base, 
externally paler, white above, nearly equal, smooth, shining. Ring 
persistent. Gills rounded behind, adnate, slightly ventricose, at first 
pallid, afterwards cinnamon. Spores profuse.—On stumps, elder, etc. 
Cespitose. Esculent, not uncommon. 
Allied to 4. pudicus and the next species, but differing in habit, as 
well as in many points of structure, from both. At first I regarded it 
as a variety of 4. pudicus, but since receiving from the Rev. M. J. 
Berkeley what he believes to be the true Æ. pudicus of Fries, I am no 
longer disposed to regard this as the same plant. Mrs. Hussey's 
figure (series ii. t. 31) has just the habit and many of the features of 
A, leochromus. 
Acartcus (Pholiota) capistratus, n. s.; pileo carnoso, convexo, 
subviscido, margine involuto, substriato ; stipite subsequali, farcto, 
crassi, subsquamuloso ; annulo patulo, persistente, lamellis decurren- 
tibus pallido. (Plate III. fig. 4.) 
Pileus 2-3 inches, fleshy, convex, livid-tawny, rather viscid when 
moist, whitish when dry, margin folded inwards, obscurely striated. 
Stem 3—4 inches, thick, attenuated, subsquamulose. Ring large and 
spreading, persistent. Gills rather fleshy, crowded, decurrent, pallid. 
—On old stumps, elm, ete. ; subesespitose, taste rather unpleasant. Ap- 
parently not uncommon. Highgate. 
Also allied to .4. pudicus and to A. cylindraceus, from both of which, 
as well as the preceding, it may be distinguished, by its decurrent 
gills. It differs moreover in its more robust habit, and the folding in 
of the margin of the pileus.
