GUIDE TO THE MODELS OF FUNGI. 2/ 



A. rimosus is common in woods and open ground, where it 

 grows sub-gregariously ; it is readily distinguished by its longi- 

 tudinally fissured pileus. 



Sub-genus i6. Hebeloma. — There are twenty-two British 

 species oi Hebeloma, two only of which are represented by models. 

 Hebeloma agrees with Tricholoma, Ento- 

 loma, and Hypholoma ; but the spores are 

 clay-coloured, not white, rosy, or purple. 

 In all the species of Hebeloma the pileus 

 is smooth and somewhat viscid, with the 

 edge at first incurved ; the gills are sinuato- 

 adnate ; stem fleshy, fibrous, mealy at apex, 

 sometimes showing slight traces of a veil 

 or ring. 



All the species are terrestrial, strong- 

 smelling, and known or suspected to be 

 poisonous. 



152. Agaricus fastibilis Fr. — Pileus ^ ^ „ , 



11,., , , ., Fie. 20.— Type form of Hebeloma. 



pale yellowish or pale tan, compactly Agancus fastibilis Fr. (One- 

 fleshy, convexo-plane, inclined to be *'^"'*^ natural size.) 

 repand, moist, clammy, smooth, the involute margm pubescent ; gills 

 sinuate, somewhat distant, rather broad, at first whitish, then dull clay- 

 coloured, edge whitish, distilling drops in wet weather ; stalk solid, 

 fleshy-fibrous, stout, white-silky and fibrillose, white, varying pallid, 

 often with traces of an incomplete ring, rarely with a perfect ring. 



A. fastibilis grows, somewhat caespitose, in woods and woody 

 places, and by grassy roadsides near bushes and trees. Odour and 

 taste of radish, but bitterish, heavy, and disgusting, like foetid flax ; 

 poisonous. 



An examination of the model will show that the poisonous 

 A. fastibilis bears a considerable external resemblance to small 

 specimens of ^. arvensis or A.hortensis. The habitat of A. fastibilis 

 is the same as that of A. arvensis, and these species are often 

 confounded. A. fastibilis is sometimes exposed for sale in our 

 markets as the true mushroom ; it may make its appearance on 

 mushroom beds and oust the mushroom. In distinguishing these 

 attention must be paid to the odour • in one the scent is pleasant, in 

 the other disgusting. A. campestris, the true mushroom, grows in 

 open pastures, and has an ample ring, and pink, at length purple- 

 black, free gills ; A. fastibilis never has its gills pink or purple- 

 black or free. In A. arvensis and A. hortensis the gills are at first 

 rather clay-coloured or brown than pink, but they are never sinuate, 

 and no mushroom has a clammy pileus. 



Compare the illustrations of A. fastibilis and A. campestris.

 colour, darker at the disc, fleshy, gibbous or convexo-plane with an
