54 FETCH : REVISIONS OF 



Mature examples have a pileus up to 8 cm. in diameter, 

 broadly convex, then almost plane, undulating, or depressed, 

 sometimes obtusely umbonate, pale yellow, centre rough with 

 minute, erect, red-brown or purplish scales, elsewhere covered 

 with scattered adpressed scales, or smooth ; margin appendi- 

 culate ; flesh yellow, thick over the stalk. 



Stalk up to 65 cm. long, 6-11 mm. in diameter, striate or 

 coarsely fibrillose, yellow, or yellow above and brown below, 

 or streaked with purple-brown, hollow, expanding into the 

 flesh of the pileus, yellow internally, base sUghtly tomentose. 



The ring is represented by a few fibrils on the stem. 



Gills pale yellow, becoming ferruginous from the spores, 

 distant, broad (up to 1 cm.), edge irregular, broadly adnate 

 with a decurrent tooth. 



Spores ferruginous, elliptic, minutely warted 5-7 x 3"5-4/^. 



Common on coconut stumps, densely clustered, sometimes 

 connate at the base. Specimens with or without an umbo 

 occur in the same cluster. In comparatively dry weather, 

 or in the sandy coconut districts, the pileus remains broadly 

 * campanulate and yellow, but in wet weather it is repand or 

 plane, and the sodden specimens are deep red-brown, some- 

 times yellow in the centre, with a striate margin ; it is most 

 often collected in this state. The specimens developed in 

 drier weather retain the purple tint in the scales, and are often 

 streaked with purple at the base of the stem. 



Berkeley and Broome's specimens of Armillaria rhodomala, 

 Flammulasapinea, and Flammula dile/pis have been examined, 

 and fresh specimens have been compared with these and the 

 original paintings. 



9.— Psalliota alphitochroa (B. & Br.), Fetch. 



Pileus 2-5 cm. in diameter, conico-campanulate, then plane, 

 or repand, centre obtuse or depressed ; grayish- white , densely 

 covered with minute , powdery scales or warts ; the centre 

 covered by a smooth, glabrous, somewhat livid patch, con- 

 tinuous in the young specimens, broken into separate scales, 

 or fissured, or recurved and cup-shaped in mature specimens : 

 margin striate, appendiculate : flesh thiri, red-brown when 

 cut.
