GUIDE TO THE MODELS OF FUNGI. 1 3 



Sub-genus 4. Tricholoma. — There are more than seventy 

 British species of Tricholoma, of which seven only are represented 

 by models ; all the species are truly terres- 

 trial, and none are marked by a central 

 depression of the pileus. The sterri has 

 neither volva nor ring ; the gills are never 

 free from the stem, but are distinctly 

 sinuate. None have been recorded as 

 poisonous, although a few may be sus- 

 pected, as A. sulphureus, which has an 

 offensive odour ; A. saponaceus, which 

 smells of soap ; and A. sejundus, which 

 has a bitter taste. 



Sometimes species placed under Riis- 

 sula, Lactarius, and Hygrophorus are con- 

 founded with Tricholoma : but attention r.- „ ^ <■ ^-r • u 1

gills of the latter, the rigid, fragile sub- (One-third natural size ) 



stance of Russula, the milky juice of Lactarius, and the waxy non- 

 membranous gills of Hygrophorus. 



10. Agaricus sejunctus Sow. — Pileus dull light yellow inclining 

 to olive, streaked with brownish fibrils and viscid in wet weather ; 

 flesh fragile; gills broad, somewhat distant, shining white, not 

 changing colour ; stalk solid, smooth, shining white. 



This is a rare species, with an odour like new meal and a bitter 

 taste. It occurs usually in fiir plantations. 



11. Agaricus rutilans Schaeff, — Pileus dry, variegated with 

 purple and ferruginous-brown down on a yellow ground ; flesh 

 bright yellow ; gills crowded, golden yellow ; stalk large, light 

 yellow, variegated with purple. 



One of the handsomest of British Agarics. It is found in pine 

 woods, frequently on or near stumps. Inodorous. 



12. Agaricus terreus Schaeff. — Pileus downy and mouse-grey 

 in colour, umbonate, inclining to split, and very brittle ; gills broad, 

 sinuate, somewhat distant, white, then grey ; stalk thick and solid. 

 Inodorous. 



This common species occurs in beech and mixed woods, and in 

 hedges near beeches, sometimes in large numbers. There is a 

 shining-white variety. 



13. Agaricus murinaceus Bull. — Pileus dry, silky, scaly, mouse- 

 coloured, and brittle ; gills broad, distant, and cinereous ; stalk stuffed, 

 twisted, and variegated with minute scales. The whole plant be- 

 comes cinereous. Odour strong and alkaline ; taste bitter. 



A rare inhabitant of open woods and pastures.
