GUIDE TO THE MODELS OF FUNGI.

adnata, very crowded, sulphur-yellow, then sulphur-green, at length 

 purplish-green ; stalk hollow, thin, flexuous, Cbrillose, yellow. 



A. fascicularis is extremely common ; it appears from early 

 spring to early winter, on or about stumps. Odour and taste bitter- 

 nauseous, sickening. Poisonous. 



Specimens of A. fascicularis were exhibited at the Woolhope 

 Club, Hereford, in 1872, with stems 4 ft. long.

then brown, 



becoming 



pale round the margin, convex, obtuse, 

 irregular by the pressure of adjoining pilei, downy-scaly, overlying 

 darker scales; flesh white; gills adnate, crowded, whitish, then 

 brown-purple, edge whitish, distilling tear-like drops in wet weather ; 

 stalk hollow, somewhat thickened at the base, fibrilloso-scaly, brown- 

 ish-white ; Cortina fibrillose, appendiculate, white. 



A. lacrymabundus is common, and grows in clusters on the 

 ground or on and about stumps in woods and fields. It is some- 

 times sold for the pasture mushroom, and often used as an in- 

 gredient for ketchup. 



SuB-GENUS 24. Psilocybe. — There are twenty-two British species 

 oi Psilocybe, only one of which is represented by a model. Psilo- 

 cybe agrees in structure with Collybia, 

 Leptonia, and Naucoria ; but the spores 

 are purplish-black, not white, rosy, or 

 brown. Nearly all the species of Psilocybe 

 are terrestrial ; some grow in clusters, all 

 are scentless, and none are edible. 



65. Agaricus semilanceatus Fr. — 

 Pileus acutely conical, resembling a minia- 

 ture broad spear-head in section, never 

 expanded, with the slightly striate mar- 

 gin at first bent inwards, viscid, and dull 

 yellowish-brown in colour ; gills ascending 

 to the summit of the acute cone, adnexed, 

 linear, crowded, becoming purple-black ; F'^^-^^I^VTyP^.^Xceu's'^^^^^^^^^ 



stalk long, thin, tough, hollow, with a third natural size.) 



pith, flexuous, smooth, cortinate when young. 



Common in the summer and autumn in dungy places among 

 grass in pastures and by roadsides ; it generally grows in numbers. 

 Dr. Henry Wharton, in the Transactions of the Essex Field Club 

 (vol. iv., p. 56), says this fungus has often been fatal to children. 



GENUS II.—COPRINUS Pars. 



The species of Coprinus do not wither or become putrescent, 

 as in Agaricus, but dissolve into an inky fluid. All the species ot 

 Coprinus are fugacious ; some are extremely rapid in growth. They
