LEUCOSPORI. 85 



Among grass by wayside. Greenings, 1868. Nov. ciitocybe. 



The spinulose spores mark this as a distinct species. It differs in habit 

 from A. geotropus, which has even spores. Saunders and Smith figured the 

 plant as A. subinvolutus Batsch, which Fries at first regarded as a variety of 

 A. geotropus. In ' Hym. Eur.' Fries records it as a distinct species, and refers 

 to the figure of Batsch as doubtful. Berkeley having found the true plant of 

 Batsch, it becomes necessary to change the name of Smith's plant. Spores

169. A. geotropus Bull. Pileus 4-7.5 cent. (iX~3 in.) broad, 

 tan-flesh-colour, truly fleshy, convex then piano-depressed, com- 

 monly gibbous, even, very smooth, moist in rainy weather, when 

 young spotted as with drops, the spots commonly vanishing with 

 age; margin thin, pubescent, inflexed ; flesh white. Stem 5-7.5 

 cent. (2-3 in.) long, solid, fleshy, not elastic, slightly attenuated 

 upwards, somewhat flbrillose, white, becoming yellow. Gills 

 deeply decurrent, simple, 4-6 mm. (2-3 lin.) broad, somewhat 

 crowded, white, but becoming pale. 



Corresponding with A. maximus, but firmer, smooth, and more changeable 

 in colour. The pileus is thinner and the gills are less crowded than in A. 

 gilvus, &c. It varies with the stem curt.

170. A. splendens Pers. Pileus 7.5 cent. (3 in.) broad, pale- 

 yellowish becoming yellow, somewhat fleshy, thin especially round 

 the shortly reflexed margin, piano- depressed, at length infun- 

 dibuliform, even, smooth, shining. Stem 4-5 cent. (iX~ 2 in -) 

 long, 8-10 mm. (4-5 lin.) thick, solid, sometimes equal and 

 straight, sometimes attenuated from the base, ascending, even, 

 smooth, of the same colour as the pileus. Gills deeply decurrent, 

 thin, crowded, simple, white but becoming light-yellow when old. 



It varies with the pileus excentric, and in larger specimens with the margin 

 repand. Pileus not flaccid, much thinner than that of A. gilvus. Gills less 

 crowded. Flesh white. Intermediate between A. gilvus and A. flaccidus. 

 Commonly single, not caespitose like A . inversus and A . flaccidus.
