NEW AND RARE BRITISH HYMENOMYCETOUS FUNGI. 
By Worruineron G. Smita, Esq, F.L.S. 
(PLATE XCV.) 
The warm and showery spring of the present year was highly 
favourable to the growth of fungi. Many species appeared that had 
not been observed for years previously, and others that were either 
altogether new to science or new to Britain: of the species that came 
under my own observation I select the following for the ‘Journal of 
Botany.’ 
A. (Flammula) decipiens, n. sp.; ceespitose; pileus 1 inch across, 
convex, fleshy, minutely squamulose, dry, rich brown, becoming 
pallid, umbo almost white; stem 2 in. high, often swollen, eit 
broad, truly decurrent, luminous brown; fles within icc 
bright brown at base; spores bright tawny, ring none. 
On the 13th June of the present year I first found this curious species 
in Epping Forest; it was growing abundantly about burnt gorse stumps, 
on burnt earth and charcoal, in open places in the forest, in company 
with 4. (Flammula) carbonarius, Fr. Like the last-named species, it 
is inclined to be fascieulate, and the groups of one and the other were 
so intimately mixed up and confused together that it was impossible to 
gather one without the other. Added to this, the pilei of the two spe- 
cies greatly resembled each other in colour, and the peculiar habitat on 
charcoal and burnt earth was the same. Owing to these deceptive pe- 
culiarities, and because Mr. Berkeley, to whom I sent specimens, believes 
it to be undescribed, I propose to describe it under the name of Agaricus 
decipiens. Though at a first glance it resembles 4. carbonarius, it is 
on examination a totally different thing, as may be seen by referring 
to ‘Journal of Botany,’ Vol. VI. t. 75. It differs greatly in the 
attachment of the gills, for whilst they are adnate in A. carhonarius, 
hes belongs to Fries’ second section of Flammula (Lubrici), they 
re decurrent in the new species, which belongs to Fries’ fourth section 
of Flammula a) and is nearly allied to Agaricus hybridus, 
picreus, sapineus,
