NEW BRITISH FUNGI. 
whilst Ag. purus does not change colour at all. Spores in Ag. 
pums shorter and ovoid, whilst in this species they are regularly 
elliptical. Allied to Ag. zephirus. 
Agaricus (Mycena) excisus, Lasch. Linn., vm., 538. 
Pileus campanulate convex, disc rather fleshy, somewhat umbo- 
nate, rugulose (bay or brownish) ; stem firm, tough, rooting, even, 
becoming brownish ; gills ventricose, thick, distant, connected by 
veins, narrowed and cut out behind, nearly free. B. fy Br. Ann. 
N. H. f No. 1930. 
On trunks. Hothorpe, Norths. 
“Magnificent specimens occurred Nov. 17, 1881, at the above 
locality. Pileus 3 in. across, stem 4 in. high, root 2 in. long. 
The specimens were either solitary or subcaespitose, gills purplish, 
strongly cut out behind. The fig. Bull. t. 518 I. is more charac- 
teristic of the specimens than that in Fries’ leones, taken from 
smaller and probably more superficial individuals.” — B. <$• Br. 
Figures of this form will be given, plate 148, of “ Illustrations 
of British Fungi.” 
Agaricus (Omphalia) buccinalis, Sow., t. 107. 
This is certainly no form of Ag. umbelliferus , and it is too fleshy 
to be the same as A. stellatus. It is, as Sowerby says, not un- 
common, and is in great perfection this Jan. 8, 1882. It has the 
habit of A. ptychophyllus, Cd., a species not noticed by Fries, but 
the gills are not plicate. B. & Br. Ann. N. H., 1930.* 
Agaricus (Omphalia) directus, B. Br. 
White,- very slender, pileus nail-shaped, flat on the apex, stem 
ascending, clad with long hairs at the base, gills decurrent. B. <J* 
Br. Ann. N. H., No. 1931. 
On dead leaves. Chiselhurst. 
Stem slightly rufous, thread-like, not an inch high. 
Agaricus (Pleurotus) pantoleucus, Fr. lc., t. 88,/. 2. 
Wholly white ; pileus excentric, fleshy, dimidiate, spathulate, 
even, smooth, rather depressed behind, margin entire, stem short, 
not rooting, solid, ascending, smooth ; gills decurrent, crowded, 
simple, severed at the base. B. Br. Ann. N. H., No. 1932. 
Blown out of a tree at Coed Coch during the gale of Oct 14, 
1881. Exactly the plant of Fries, of which a drawing was origi- 
nally sent from Sweden under the name of A. spodoleucus. 
Agaricus (Pleurotus) revolutus, Kickx, p. 158. 
Pileus convex-flattened, depressed in the centre, of large size, 
fleshy, firm, dry, elastic, margin regularly and broadly revolute, of 
a smoky colour with a yellowish tint, becoming grey or lead colour, 
darker in the centre ; gills decurrent, not anastomosing, white, 
serrated. Stem obtuse, smooth, or slightly tomentose. B. Br. 
Ann. JV. H ., No. 1933. 
On a poplar tree. Penzance. 
A magnificent Agaric, clearly that of Kickx, but considered by 
Fries a form of A. salignus. It is clearly the same with A. corti- 
catus, Saund. & Sm.,t. 4, f. 2. The stem is short but distinct 
and swollen. — B. Br.
