58 AGARICUS. 



Tricholoma. Allied to A. gambosus. B. & Br. Fries remarks that the plant of Schaeffer 

 differs in the longer stem, in the pileus being conical then expanded, becoming 

 hoary-white, and in the gills being at length distant, but that there can be no 

 doubt they are the same. My specimens agreed exactly with the description 

 of Fries. Forming a large ring on a grassy place on the shore of an estuary. 

 Name tigris, a tiger. Spotted like a tiger. Sch&ff. t. 89. Fr. Icon. t. 41.

VI. SPONGIOSA. 







* Gills not changing colour. 



108. A. Schumacher! Fr. Pileus 7.5 cent. (3 in.) broad, of one 

 colour, cinereous-livid, fleshy, compact, convex then flattened, 

 obtuse, regular, well formed, even, smooth, moist (not hygroph- 

 anous) in rainy weather, the slight margin, which exceeds the 

 gills, inflexed ; flesh spongy, white. Stem 7.5-10 cent. (3-4 in.) 

 long, as much as 12 mm. (% in.) thick, solid, stout, equal, villous 

 and sometimes ventricoso-bulbous at the base, otherwise naked, 

 slightly striate, white, externally fibrous. Gills emarginate, very 

 crowded, plane, 6-8 mm. (3-4 lin.) broad, white. 



Its entire nature and structure are those of A. personatus, and it can only be 

 compared with A. nebularis on account of the colours (the pileus being cinere- 

 ous, naked however). The stem being wholly fleshy and the gills being at the 

 first emarginate, evidently determine it a Tricholoma.

Agreeing very closely with the figure in ' Fl. Dan.' especially as regards the 

 gills. B. 6. Br. Name after Schumacher. Fr. Monogr. i. p. 85. Hym.

109. A. patulus Fr. Pileus 6-10 cent. (2)4-4 in-) broad, pallid- 

 cinereous, fleshy, firm, convexo-plane, obtuse, often repand, even, 

 smooth, in no wise tiger-spotted ; flesh moderately thin, not com- 

 pact, white. Stem 5-10 cent. (2-4 in.) long, 1-2.5 cent. (}4-i in.) 

 thick, fleshy-fibrous, solid, firm, equal, somewhat elastic, smooth, 

 shining white. Gills constantly and equally emarginate, almost 

 free, crowded, comparatively narrow, 4 mm. (2 lin.), plane, somewhat 

 veined at the sides, whitish. 



Inodorous. Solitary or growing in troops, or somewhat caespitose. The 

 colour of the pileus passes into very pale yellowish. It cannot be com- 

 pared with any of the neighbouring Tricholomaia, but rather with the 

 irregularly shaped Clitocybcs, especially when caespitose. It must not be 

 confounded with A. decastes. Dependent on the weather ; very luxuriant in 

 some rainy seasons, absent in very dry ones.
