*Bol. lacinia'tus. Tubes very short: pores- blossom-coloured : pileus 
brownish or ash-coloured, arched, warty, thin, fringed at the 
edge. 
Tubes very short and slender; pores very minute, blossom colour. Pileus 
very thin, lobed ; lobes arched and hanging over each other, an inch wide 
and one and a half long, leathery, deeply fringed at the edge, surface pus¬ 
tular, mottled, yellow brown or ash-colour. Root and thickest part of 
the pileus like cork. Description and drawing from Mr. Stackhouse. 
Bulliard’s Bol. imbricatus seems something like it, but is a much 
larger and more luxuriant specimen, perhaps also in an older state, for the 
pores have a deeper shade of colour. It however is more bright in its 
tints, and wants the warty tubercles on the pileus. 
(Laciniated Pustular Boletus. E.) Comb Wood near Bath. Mr. 
Stackhouse. 
*Var. 3. Pileus smooth, downy, sending out root-like suckers from the 
under side. 
Substance hard, leathery. Dull blossom-colour underneath. It is rather 
yellower than the preceding, and had some brown striae on the pileus. 
Found near the former, of which it may be only a variety. Mr. Stackhouse. 
Bol. abieti'nus. Pores angular, purplish, changing to brown : pileus 
gently convex, wrinkled, woolly, greyish, whiter at the edge. 
(Hook. FI. Lond. 180. E.)— Dicks. Fasc. iii. 9. 9—(Purt. 13. E.) 
Stemless, generally tiled one upon another. Pileus thin, convex, but flat 
towards the edge, wrinkled and knotted, cottony, greyish, paler towards 
the edge which is either scolloped or entire. Zones narrow, impressed. 
Pores angular, with one or two prominent teeth. Dickson.) Its dura¬ 
tion is at most six months. FI. Lond. E.)

Sometimes grows very much tiled, the lobes forty or more ; the whole mass 
half a yard in length and a foot or more in breadth. 
In its first state it is soft like a custard. Mr. Stackhouse. 
Tubes yellow, not longer than one-tenth of an inch. Pores very minute, 
irregular in shape. 
Pileus nearly semi-circular, six inches radius, in shape like the under shell 
of a very large oyster inverted, colour bright aurora, streaked; thin edge 
bordered with yellow, for about one-tenth of an inch in breadth. Flesh 
thin, soft white, sometimes stained red near the upper surface, but never 
yellow. Stem next to none, but a thick mass near two inches in diameter 
attaches the plant to the tree.
