GUIDE TO THE MODELS OF FUNGI. 



weather, leaving the pilous plane and dull yellowish ; gills adnate, 

 not crowded, whitish, then fuscous, becoming purple-brown; stalk 

 hollow, equal, at first scaly or fibrillose below the ring, viscid, blue- 

 green ; ring distant. 



A. cemginosus grows in dungy places in woods, fields, and road- 

 sides, often appearing in very wet weather late in the autumn or 

 in the early winter. Poisonous. 



6i. Agaricus semiglobatus Batsch. — Pileus hemispherical, never 

 expanded, slightly fleshy, even, viscid, dull light 3'cllow ; gills adnate, 

 very broad, dull purple-brown, clouded with black; stalk hollow, 

 straight, equal, smooth, yellowish, generally stained with the blackish- 

 purple spores, glutinous ; ring incomplete, distant, viscous. 



Extremely common on horse-dung from early spring to early 

 winter. Said to be poisonous. 



Sub-genus 23. Hypholoma, — There are twenty-one British 

 species of Hypholoma, three of which are represented by models. 



Hypholoma agrees in structure with Tricho- 

 loma, Entoloma, and Hebeloma ; but the 

 spores are purple-black, not white, rosy, 

 or brown. With one or two exceptions, 

 all the species grow on stumps in clusters ; 

 the ring is represented by a circle of fine 

 dark-coloured hairs or fibrils on the stem, 

 and similar fibrils belonging to the veil 

 adhere to the margin of the pileus ; the 

 gills are adnate or sinuate. None of the 

 species are edible ; many are bitter- 

 nauseous in taste. 



"^ 62. Agaricus sublateritius Schaeflf. — 



^'\"^Z^%J:^lTs ffscVuYans" Pileus ycllow, with a reddish disc, dry and 

 ijuds. (One-quarter natural smooth; flcsh white, becoming yellowish; 



gills at first faintly olivaceous-yelloiv, then 

 dull olivaceous-purple ; stalk pale yellowish, rusty-brown at the 

 base, curved, attenuated downwards, furnished with a purplish-black 

 fibrillose ring. 



Generally grows in a cacspitose manner, and is common on old 

 stumps ; often confounded with other species of similar colour, 

 especially with the common A. Jascicularis. The taste is strong, 

 nauseous-bitter, and this distinguislies it from some, but not all, 

 of its allies. Probably dangerous. 



63. Agaricus fascicularis Iluds.— Pileus light yellow, with a 

 reddish-brown disc, convex, then flattened, smooth, dry, the lower 

 pilei of the crowded overlapijiiig clusters generally stained with the 

 purplish spores shed from the pilei above; flesh light yellow; gills
