Amongst leaves, especially oak-leaves. May. — Oct. Very common. — 

 " Solitary or tufted, very variable in size and colour. Pileus I — 3 

 inches broad, whitish, pinkish, yellowish or livid, plane, sometimes 

 depressed, fleshy, thin, tender, easily injured, of a watery substance. 

 Gills free, white or very pale flesh-colour, soft, tender, entire or serrate, 

 numerous. Stem 2—3 inches high, \—^ of an inch thick, shining, 

 splitting, sometimes twisted, of the same colour as the pileus, but the 

 summit is generally darker and pinkish. The whole plant is fragile and 

 the pileus easily detached from the stem." Grev. I. c. I copy the above 

 description from Dr. Greville, as applying more generally than my own 

 notes which are taken from red-stemmed varieties. In those neither 

 the pileus nor stem are so tender, but this arises probably from their 

 being examined when the pileus had become pale in consequence of 

 having parted with a great deal of its moisture. I believe A. arjuusus 

 to be only a variety. Fries seems never to have found specimens about 

 which he could satisfy himself, and mine differ only from small varieties 

 of A. dryophdus in the scattered fasciculate pubescence of the stem. I 

 have found a variety o'i A. peronatiis'\n\\\\\c\\ the strigae were arranged 

 exactly in the same way, so that not improbably the appearance is 

 entirely owing to casual circumstances. Persoon quotes A. mollis, ^^i\\\., 

 adding" ex ipso auctore ;" but, allowing all that can be allowed for the 

 depression of the pileus and consequent decurrence of the gills, the 

 figure will show this to be almost impossible. He is probably right in 

 su[)posing A. hariolorum. Bull. t. ^i^o. f. 2, to which A. iiemoralis, 

 Wi t li. i\nd Part, is referred, a variety of A. peroiiatus. Bulliard's 

 other plate seems to be something quite diflerent.
