20 GUIDE TO THE MODELS OF FUNGI. 



white; gills broad in front, adnexed, almost free, distant, white, 

 frequently marked with foxy-red spots and blotches; stalk rigid, 

 straight, equal, naked, hollow, longitudinally grooved, silvery grey 

 varying to livid and azure blue, and of shining metallic appearance. 

 A comparatively large and extremely common fungus on 

 stumps. It appears in autumn or early wmter, and grows in 

 clusters. Odourless. 



34. Agaricus epipterygius Scop. — Pileus campanulate, at length 

 more expanded, never depressed, striate, covered with a very 

 glutinous separable commonly cinereous — varjnng rufescent or 

 yellowish — pellicle; gills sinuato-decurrent, cinereous, rufescent; 

 stalk tough, hollow, even, rooted and fibrillose at the base, glutinous, 

 yellow varying to pallid-cinereous or whitish. 



This is a common, pretty, fragile, and glutinous species, in- 

 habiting woods, where it grows on and among dead ferns, twigs, 

 leaves, etc. ; it is usually gregarious or caespitose, but sometimes 

 solitary. Odourless. 



35. Agaricus corticola Schum. — Pileus hemispherical and thin, 

 deeply striate, and obsoletely umbilicate, smooth or pruinose, 

 generally blackish, becoming bluish, fuscous, or ashy-grey; gills 

 adnate, sinuate, broad, distant, paler than pileus; stalk generally 

 incurved, smooth or slightly furfuraceous, hollow, paler than the 

 pileus. 



A. corticola is very small and common on the mossy trunks ot 

 trees, where it grows abundantly from midsummer to early winter; 

 soon withering in dry weather, but reviving with moisture. 



Sub-genus 8. Omphalia. — There are nearly forty British species 

 of Omphalia, two of which are represented by models. All the 



species are small ; the pileus is generally 

 depressed, the gills decurrent. Some 

 species of Omphalia grow on the ground, 

 others in moist situations among or upon 

 dead twigs, leaves, mosses, etc. They are 

 most commonly met with in wet weather, 

 and in hilly and woody places. No species 

 is known to be edible. 



36. Agaricus pyxidatus Bull. — Pileus 

 membranaceous, pellucid, umbilicate, then 

 infundibuliform, radiato-striate, very hy- 

 grophanous, smooth and red-brown when 

 _. T- r r r^ u , moist, paler and slightly silky when dry;
