Amongst grass, &c. 



In the typical form the stem is 4-5 in. long, in form media 

 2-3 in., in form minor little more than 1 in. ; pileus subum- 

 bonate, fuliginous when moist, subolivaceous ; gills ventri- 

 cose, 2 lines broad. (Fries.) 



Tufted. Pileus fleshy, brown-orange, paler at the margin, 

 when young sericeous, 2-5 in. broad, convex, sometimes 

 glutinous, rarely scaly. Lamellae adnate, rather broad, pale, 

 greyish, at length somewhat greenish, numerous. Stipes 

 25 in. long, about -3- in. thick, firm, cylindrical, crooked, 

 scarcely quite solid, but filled with a fibrous spongy mass. 

 Flesh yellowish-white. Veil fugacious, staining the stipes 

 more or less. Taste bitter. (Grev.) 



Psathyrella gracilis. Fr. 



Pileus | 1 in. across, subinembranaceous, conical, then ex- 

 panded, slightly striate when moist, hygrophanous, brown- 

 ish when moist, pale dingy yellow or tinged with rose- 

 colour when dry and without striae ; gills broadly adnate, 

 about 2 lines broad, rather distant, broadest behind, grey- 

 ish-black ; margin with a slight rosy tint ; stem about 3 in. 

 long, 1-H lines thick, straight, naked, pallid, hollow ; spores

On banks under hedges, &c. Fries says that a corrugated 

 variety exists that very much resembles Psathyra corrugis. In 

 Cooke's figures the stem is represented as being attenuated 

 into a rooting base. 



Gregarious, fragile owing to its rigidity. Stem hollow, 

 very straight, 3 in. long and more, scarcely a line thick, 

 equal, naked, glabrous, whitish, base rootless, furnished 

 with white down. Pileus membranaceous, campanulate, 

 obtuse, i 1 in. broad, glabrous, even, slightly pellucido- 

 striate towards the margin, smoky, livid, &c., but hygro- 

 phanous; when dry clay-colour, rosy, or whitish, soft to 

 the touch. Gills broadly adnate, generally broadest behind
