98 NEW AND RISE HYMENOMTCETOTJS FUNGI. 



from all other described species. Its nearest ally is A. carneo-griseus, 

 B. & Br. [Tab. 161, figs. 14—20.] 



3. Agaricus {Eccilia) atropunctus, P. Pileus somewhat fleshy, 

 soft, hemispherical, pale-cinereous; stem somewhat tough, pallid, 

 smooth, clothed with black punctitbrm squamuloe ; gills decurrent, 

 arcuate, distant, alternate, cinereous-flesh-coloured ; P. Syn. p. 353. 

 Amongst beeches, extremely rare. Gregarious, small, pileus ^--f in. 

 across. Fr. Epic, p. 159. ^o\. ed., p. 212. 



Our plant so thoroughly accords with Persoon's description that 

 we can have no hesitation in referring it to the species above quoted; the 

 only point of divergence is in the habitat, which we take to be of 

 little moment. Fries says in both editions of the *'Epicrisis" that 

 the plant is unknown to him. 



Dr. Bull, of Hereford, found this agaric in October, 1874, in an 

 oak wood at Dinmore, near Hereford, growing sparsely over a space of 

 some eight or ten feet square, in small clusters amongst moss. Its 

 character is very distinct, and after being once seen any imperfect or 

 broken fragment would be recognised directly. The taste is disagree- 

 able, the whole plant brittle, and the pileus inclined to be somewhat 

 irregular. [Tab. 161, figs. 10—13.] 



4. Boletus sulfureus, Fr. — Pileus compact, convex, then plane, 

 silky-tomentose, with innate flocci, pulphur-coloured ; stem firm, 

 ventricose, even, smooth, of the same colour as the pileus ; tubes 

 adnato-decurrent, short, minute, compound, sulphur-coloured, at 

 length greenish. 



From a wide-spreading fleecy golden-coloured mycelium it springs 

 in dense clusters, after the fashion of Agaricus spectahilis. Stem 

 compact, 1-2 in. long, an inch thick, self-coloured, but at length 

 acquiring a dirty ferruginous tint. Pilei at first hemispherical, then 

 by mutual pressure twisted and concrescent ; margin acute, involute 

 when young. Flesh yellow, turning more (r less blue when broken, 

 but when exposed for some time to the air golden, under the tubes 

 occasionally reddish. Tubes 1-2 lines long, adhering more closely 

 than usual, changing colour when touched, at lengtli spotted with 

 feiTuginous stains. Spores yellow, then olivaceous. Fr. Epic, 

 p. 413. Nov. Ed., p. 502. 



For the addition to our Flora of this most interesting and rare 

 species (for Fries himself appears to have only met with it once) we 

 are indebted to the Rev. James Keith, of Forres, N.B., who sent it to 

 us in Sept., 1873, from Aviemore, Inverness-shire, where it was 

 detected growing in abundance amongst sawdust at Loch-an-Eilan. 

 The plant grows in masses, and has exactly the appearance and 

 habit of Agaricus spectahilis, to which Fries compares it. Some of 

 the Aviemore clusters were, says Mr. Keith, larger than a man's 

 head, and consisted of upwards of fifty individuals so densely packed 

 together that those in the centre were crushed out of all shape, and 

 only those at the margin were at all regularly developed. The saw- 

 dust where the Boleti grew was lull of the mycelium, which was of 

 the same colour as the fungus. The spores are unusually small, and 

 contrary from what might be expected from this plant and its habitat, 

 Bo letus sulfureus is tasteless. [Tab. 162, figs. 1 — 3.]
