Bull. 451 —Sowerby 34. 
Tubes decurrent, short, deep orange or earthy red. Pores browner, open 
irregular. 
Pileus yellow, flat, thin at the edge, three inches over. Flesh thick, tinged 
with yellow. 
Stem dirty greenish yellow, cylindrical, one and a half to two inches high, 
three-eighths of an inch diameter. 
(Peppery Boletus. E.) First found by Mr. Sowerby in Hainault Forest, 
towards Chigwell Row, Essex, in tolerable plenty; who informs us that 
its pungency on the tongue and throat is like that of Capsicum.

Bol. nummula'rius. (Bull.) Tubes very short, buff colour: pileus 
colour of horn, convex, dimpled: stem colour of horn, black at 
the base. 
Bull. 124 —(Sowerby 89. E.) 
Tubes loose from the stem, buff, very short. Pores angular; general sur¬ 
face underneath the pileus concave. 
Pileus the colour of brown horn, with a black circle at the edge gently con¬ 
vex, but hollowed in the centre; tough like leather, smooth, very thin, 
from half to one and a half inch diameter. 
Stem colour of brown horn, black at the base, smooth, two inches high, 
thick as a goose quill. 
Bulliard figures the stem as more or less eccentric, and says it is always 
so, but the specimen from which the preceding description was taken, and 
others which I have seen since, are exceptions. Dickson observes that it 
is chiefly found on slender decayed branches of hazle. Fie quotes the fig', 
of Bulliard, cited above, and in his second fasc. refers Bolt. 83, to this 
plant, but Bolton’s is a different species.
