GUIDE TO THE MODELS OF FUNGI. 



pressed pilose squamules, continued into the veil at margin ; flesh 

 hard, sulphur-yellow; gills adnate or adnato-sinuate, crowded, 

 yellow, then rusty-brown ; stalk solid, hard, ventricose, attenuated, 

 and rooting downwards, mealy above, smooth or squamulose below 

 the spreading persistent ring. Taste when raw, strong, disagreeable, 

 bitter-aromatic. 



A. spcdobilis, represented by two models, is a very handsome 

 bright golden-yellow species, which grows in clusters on oak stumps 

 from August to November. It is often confounded with A. aureus, 

 which, however, is always terrestrial. 



49- Agaricus mutabilis Schacff. — Pileus cinnamon when moist, 

 paler when dry, hygrophanous, slightly fleshy, usually obtusely 

 umbonate, smooth, but when young sometimes squamulose ; gills 

 adnato-decurrent, crowded, pallid, then cinnamon ; stalk rigid, 

 stuffed, then hollow, equal or attenuated downwards, slightly shaggy 

 as far as the ring, dark brown at the base; ring membranaceous, 

 externally squamulose. 



A. vtutabilis, although very variable, is easily recognised in all 

 its forms; it grows in dense tufts on stumps in spring, summer, and 

 autumn. It is said to be not poisonous, and has sometimes been eaten. 



Sub-genus 15. Inocyhe. — There are forty-nine British species of 

 Inocybc, of which two only are represented by models. The pileus 



in all the species is adpressed silky-fibril- 

 lose ; gills usually sinuate, but varying 

 adnate and decurrent, never cinnamon- 

 pulverulent. All are terrestrial, and mostly 

 nauseous smelling ; none are edible. 



hiocyhe (with the next sub-genus 

 Hebcloma) agrees in structure with Tricho- 

 loma, Entoloina, and Hypholoma ; but the 

 spores are ferruginous-fuscous, not white, 

 rosy, or purple.

slightly adncxcd, thin, crowded, whitish, 

 then dusky; stalk .solid, firm, equal, white, silky-fibrillose or velvety. 

 Common in woods. Almost scentless. 



51. Agaricus rimosus Bull. — Pileus satiny-brown, with the 

 whitish llcsli exposed in longitudinal cracks, umbonate; flesh 

 white; gills free or slightly adncxcd, somewhat ventricose, whitish, 

 then fuscous and rusty-brown, edge serrulated, pallid ; stalk solid, 

 firm, fibrous within, thickened and fibrillosc at the base, mealy 

 upwards, becoming yellowish or brownish, sometimes white; the 

 thin veil fugacious. Odour earthy.
