l6o AGARICUS. 



Omphaiia. Among moss on lawn. Coed Coch, 1878. Oct.-Nov. 



Pileus 8-15 mm. broad. Stem 2-3 cent. long. Spores 6-7x3-4 mk. B. 

 Name >//ev66s, false. Like spurious Marasmius androsaceus. Bull. t. 276.

346. A. griseo-pallidus Desm. Pileus 6-8 mm. (3-4 lin.) 

 rarely more broad, fuscous-grey then becoming hoary, slightly 

 fleshy, convex then plane, umbilicate, even, smooth, slightly 

 shining, but hygrophanous, here and there unequal and excentric; 

 margin defiexed, but scarcely inflexed. Stem curt, about 8 mm. 

 (4 lin.) long, stuffed, fistulose only when old, slightly firm, equal 

 or thickened upwards, smooth, fuscous. Gills decurrent, broader 

 behind, distant, rather thick, of the same colour as the pileuswhen 

 moist, darker when dry inasmuch as they do not become pale. 



Readily recognised by its minuteness. It is like a diminutive state of A. 

 umbelliferus, and is analogous with A. rusticus. As regards the gills it is 

 intermediate between A. retostus and A. umbelliferus.

347. A. stellatus Fr. Wholly white. Pileus 6-8 mm. (3-4 

 lin.) broad, truly membranaceous, convex, umbilicate, diaphanous- 

 striate, smooth. Stem scarcely 2.5 cent, (i in.) long, stuffed, at 

 length fistulose, fragile, filiform, equal, the dilated base strigoso- 

 radiate. Gills decurrent, very distant, distinct, thin, broad, not 

 triangular. 



From situation the stem is often incurved. It is dilated at the base as in 

 Mycence Basipedes. Thinner than A. griseo-pallidus, &c. Nearest to A. 

 integrellus, but distinct in its broader gills, &c. 



On sticks, stems of herbaceous plants, &c. Uncommon. Feb.- 

 Nov. 



Distinguished by its thin gills from every state of A. umbelliferus. M.J.B.
