GUIDE TO THE MODELS OF FUNGI. 



A. ceri'iiius grows singly on and near stumps, and on sawdust. 

 A most variable species. 



It has been mistaken and sold for the true mushroom, which 

 has a ringed, not naked, stem, and grows in pastures, not on stumps 

 and sawdust. 



SuB-GENUS 12. Clitopilus. — There are ten British species of 

 C/it ypi/us, o{ -which one only is represented by a model. Clilopilits agrees 



in structure and habit with Clitocybe, and 

 partially with Flammida ; but the spores 

 are rosj', not white or brown. All the 

 species are terrestrial, and many are strong- 

 smelling; the gills are usually decurrent, 

 never sinuate, and the pileus depressed at 

 maturity. 



44. Agaricus prunulus Scop. — Pileus 

 flesh}^ compact, convex, then flattened, and 

 at length slightly depressed, pruinate, dry, 

 never viscid, white, rarely pale-cinereous ; 

 gills deeply decurrent, somewhat distant, 

 white, then flesh-coloured ; stalk solid, firm, 

 naked, often striate, villous at base. 



A. prunulus grows early in the autumn, 

 in clusters or rings, on the borders of woods 

 and in grass}', shady, but open places.

SuB-GENUS 13. Lcptonia. — There are thirteen British species 

 of Lcptonia, one of which is represented by a model. Leptonia agrees 

 in structure with Collybia, Naucoria, and 

 Psilocybc ; but the spores are rosy, not 

 white, brown, or purple. The species 

 are small, beautiful, bright'}', sometimes 

 brilliantly, coloured violet and blue; they 

 grow in numbers in wet wcatiier, on 

 downs and pastures, as well as in marshy 

 places; all arc inodorous except A. in- 

 canus, which has the odour of mice.

 violaceous, steel-blue, or blackish-blue,
