LEUCOSPORI. 129 



ing, slightly striate, rooted. Gills adnexed, somewhat distinct, Mycena 

 becoming pale-white. 



Inodorous, only at length nauseous. Very much allied to A. galericulatus ; 

 in habit approaching nearest to A. cohcerens. The stems are pallid at the 

 apex, but slightly tawny-bay-brown below, and glued together by villous down 

 at the base. There is a white form with hyaline stem on trunks. 



In woods, and in gardens near wood. Uncommon. Sept. 



Stem frequently proliferous, as in some species of Coprinus. M.J.B.

267. A. excisus Lasch. Pileus campanulato-convex, slightly 

 fleshy at the disc, somewhat umbonate, slightly wrinkled, date- 

 brown, fuscous-blackish. Stem firm, tough, rooted, even, becom- 

 ing fuscous. Gills ventricose, thick, distant, connected by veins, 

 hoary, narrowed behind as if cut out, somewhat free. 



In mixed wood, on trunks. Glamis, 1875, & c - Sept.-Oct. 



Pileus about 5 cent. (2 in.) broad. Stem about 7.5 cent, (sin.) long, ex- 

 ceedingly rigid and tough. The primary form is caespitose on trunks of pine ; 

 there is a smaller form, on the ground, solitary ; pileus membranaceous, the 

 darker disc wrinkled, striate at the margin ; gills very much narrowed behind, 

 hooked to the stem however by a small tooth, very distant, becoming glaucous. 

 In the colour not becoming cinereous and in the nature of the gills it clearly 

 differs from A.'rugosus, &c. Pileus 7.5 cent. (3 in.) across, stem 10 cent. (4 in.) 

 high, root 5 cent. (2 in.) long. The specimens were either solitary or subcass- 

 pitose ; gills purplish, strongly cut out behind. The fig. Bull. t. 518 /. is 

 more characteristic of the specimens than that in Fries's ' Icones,' taken from 

 smaller and probably more superficial individuals. B. & Br. Spores ellip- 

 soid often reniform or spherical, 7-9 mk. Q. Name excido, to cut out. From 

 the peculiar character of the gills. Lasch n. 538. Fr. Hytn. Eur. p. 137.

268. A. psammicola B. & Br. Pileus 6 mm. (3 lin.) broad, 

 brown, becoming paler towards the margin, hygrophanous, some- 

 what hemispherical, sprinkled with very minute particles, margin 

 striate. Stem short, not 12 mm. (6 lin.) long, about i m. (Yz lin.) 

 thick, solid, firm, rooting, umber downwards, white upwards, 

 wholly white-pulverulent. Gills in the form of a segment, shortly 

 adnate, sinuate behind. 



Odour strong but not nitrous. A small but well-marked species.
