44. Pholiota marginata, Batsch, fig. 207; Austr. Fung., 

 p. 45 ; Sacc, Syll. v , no. 3130. 



Pileus convex, then expanded, hygrophanous, moist, 

 glabrous, margin striate, honey-colour, becoming pale-tan 

 when dry, about 2-5 cm. across ; flesh thin ; gills adnata, 

 crowded, about 2 mm. broad, watery-cinnamon ; spores 

 7-8 X 4/x; stem 3-5 cm. long, 2-4 mm. thick, equal or 

 slightly thickened at the base, soft, not scaly, mealy above 

 the fugacious ring, pale-tan, base darker and surrounded with 

 white down, hollow. 



On trunks, heaps of leaves, &c. Dannevirke, New Zea- 

 land. Australia, Europe, Siberia. 



Alhed to Pholiota mutabilis, but differing in the stem 

 below the ring not being scaly, but only somewhat fibrillose ; 

 commonly smaller ; solitary or gregarious, rarely csespitose. 



* * Pileus umbonate. 



45. Pholiota sqztarrosa, Milll., in Fries' Syst. Myc, i., p. 143; 

 Sacc, Syll. v., no. 3093. 



Pileus campanulate, then expanded, often broadly and ob- 

 tusely umbonate, dry, yellowish-brown, covered with darker 

 persistent squarrose scales, 5-10 cm. across; flesh firm, 

 thickish, white but usually tinged yellow or green; gills 

 slightly decurrent, crowded, about 4 mm. broad, pale-olive, 

 then rusty ; spores rusty, 8 X 4 /x ; stem 7-12 cm. long, up to 

 1 cm. thick, slightly narrowed towards the base, more or less 

 wavy or ascending,' pale tawny-yellow or brown, and covered 

 with darker recurved scales up to the superior spreading 

 ragged ring, smooth and pale above the ring, stuffed. 



On trunks, on and near stumps, &c. Dannevirke, New 

 Zealand. Europe, United States. 



Usually growing in dense clusters ; smell strong, dull rusty- 

 orange, with darker squarrose or spreading scales on the pileus 

 and stem. Distinguished from Pholiota adiposa by the darker 

 colour of the entire fungus and the persistent scales. Poi- 

 sonous. 



46. Pholiota mutabilis, Schsiffer, t. 9. ; Austr. Fung,, p. 45; 



Sacc, Syll. v., no. 3129. 



Pileus convex, then expanded, usually obtusely umbonate, 

 sometimes depressed round the umbo, glabrous, deep cinna- 

 mon-colour, becoming paler when dry, size very variable, 

 2-5-10 cm. across ; flesh thin ; gills adnate and shghtly de- 

 current, crowded, rather broad, pallid, then cinnamon-colour; 

 spores 9-11 x 5-6 p.; stem 3-10 cm. long, rigid, nearly equal,
