488. A. depluens Batsch. Pileus as much as 2.5 cent, (i in.) 



broad, rufescent - hoary, somewhat membranaceous, resupinate 

 then reflexed, changeable in form, somewhat silky; at first with a 

 villous stem then stemless. Gills scarcely decurrent, diverging, 

 broad, ventricose, somewhat crowded, grey then rufescent. 



Spores almost rose-colour. After the type of A. variabilis it is resupinate 

 then reflexed, with a stem, which is manifest and villous in younger specimens, 

 and then vanishing, but much more changeable in form, sometimes entire 

 with a central and vertical stem, so that scarcely any form is constant. It is 

 easily distinguished, however, by its thin, watery, fragile substance, by the 

 rufescent- hoary colour (very hygrophanous), and by the pileus being so deli- 

 cately silky that it appears rather smooth, most manifestly white-villous at the 

 base however, with the margin slightly striate in moist specimens.

489. A. byssisedus Pers. Pileus 1-2.5 cent. (%-i in.) broad, 

 grey, becoming pale when dry, slightly fleshy, at length horizontal, 

 reniform, plane, even, villous ; flesh, which is of the same colour, 

 thin. Stem incurved, villous, attenuated upwards, 12 mm. ( J /4 in.) 

 long, zoned at the base with white cottony fibrils. Gills adnato- 

 decurrent, ventricose, rather broad, whitish-cinereous, then rubigi- 

 nous with the spores. 



When young resupinate. The stem is more distinct and persistent than in 

 A. depluens, &c.
