ferruginous - brown. There are 226 British species of Dermim, 

 twelve of which are represented by models. 



The Cortinarii Sive frequently mistaken for the larger Dermini- 

 but they have bright-brown spores like iron-rust, an arachnoid veil' 

 and a terrestrial habit. Many of the Dermini grow on or about 

 stumps, trunks, branches, chips, etc. 



Sub-genus 14. Pholiota. — There are twenty-eight British 

 species of Pholiota, four of which are represented by models. 

 Pholiota agrees in structure with Armillaria 



and Siropharia; but the spores are yellowish- j^ — . „ 



brown, dark brown, or reddish, not white ^^^^^ 



or purple. Nearly all the species grow on ^ 

 stumps. 



46. Agaricus aurivellus Batsch. — 

 Pileus brilliant yellow or reddish-yellcw 

 ornamented with dark adpressed spot-like 

 scales, fleshy, campanulate, then convex, 

 gibbous, moist, margin floccose when young, 

 flesh yellow at maturity ; gills sinuato- 

 adnexed, broad, crowded, at first whitish, 

 then straw-coloured, at length rusty-brown, 

 never olivaceous-brown ; stalk 



stuffed, sub-equal, at first clothed with (One-quarter natural size.) 



adpressed, floccoso-fibrillose scales, at length almost naked, yellow 

 at maturity ; ring silky, membranaceous. Odour faint. 



A. aurivellus grows on old stumps and trunks, in woods and 

 hedgerows, either in overlapping clusters or singly. It is a beautiful 

 but uncommon species. 



47. Agaricus squarrosus Miill, — Pileus dry, yellow-brown, 

 shaggy with crowded, revolute, persistent brown scales, fleshy, um- 

 bonate or gibbous; flesh sulphury-yellow; gills adnate with a decurrent 

 tooth, crowded, pallid olivaceous, then rusty ; stalk attenuated at the 

 base, stuffed, shaggy from the base to the ring with crowded 

 revolute darker scales ; ring membranaceous, entire or laciniate, 

 floccoso-radiate, of the same colour as the scales. 



A. squarrosus is very common, and grows in tufts on stumps 

 and trunks, chiefly ash, from late summer to early winter; it is 

 remarkable for its powerful and disagreeable odour, which is said, 

 however, to be sometimes absent. It is said that when cooked 

 it is not poisonous. 



There are two remarkable varieties of this fungus : one named 

 A. Mucllcri Fr,, which grows on beeches, with a pallid pileus and 

 entire ring; the other A. verruculosus Lasch., which grows on maple, 

 with a yellow scaly-papillose pileus. 



48. Agaricus spectabilis Fr.— Pileus shining, golden or tawny, 

 becoming paler, fleshy, compact, hemispherical, dry, torn into ad-
