AGARICUS. 



Psiiocybe. 744. A. scobicola B. & Br. Pileus white, convex, umbilicate, 

 smooth. Stem fistulose, somewhat equal or dilated at the apex, 

 fibrillose. Gills adnexed, broad. 



On pine sawdust. Glamis, 1877. Nov. 



Name scobis, sawdust ; colo, to inhabit. B. & Br. n. 1769. S. Mycol. 

 Scot. n. 403. C. Illust. PL 607. 



Psathyra. 



Subgenns XXXIII. PSATHYRA (WWs, friable). Veil 

 none or only universal, and floccoso-fibrillose. Stem somewhat 



cartilaginous, fistulose with a tube, 

 polished, fragile. Pileus conical or 

 campanulate, membranaceous, the 

 margin at the first straight and ad- 

 pressed to the stem. Gills becoming 

 purple or fuscous. Slender, fragile, 

 hygrophanous. [The series of tough 

 species does not exist among the 

 Psathyras ; the analogous forms will 

 be found among the tough species 

 of Psiiocybe.] Some of the last spe- 

 cies of Hypholoma and Psiiocybe are 

 very closely allied to them. The 

 Coprinarii are readily distinguished 

 by the gills being white or cinereous 

 then black, not fuscous nor becoming 

 purple. Fr. Hym. Eur. p. 304. 

 Psathyra corresponds with Mycena, Nolanea, Galera, and 

 Psathyrella. All the species grow on the ground or on trunks. 



I. Conopilei (KWVOS, a cone). Pileus conico-campanulate ; gills ascending, 

 adnexed, often free. Stem tense and straight, veil none. On the ground in 

 grassy or damp places. 



II. Obtusati (A. obtusatus).. Pileus campanulato-convex, flattened, smooth 

 or atomate, gills piano- or arcuato-adfixed. Veil none. 



III. Fibrillosi (A.fibrillosus}. Pileus and stem at the first floccose or fibril- 

 lose fro?n the universal -veil.

745. A. conopileus Fr. Pileus 2.5 cent, (i in.) or a little more 

 high and broad, whitish then becoming pale, somewhat membra- 

 naceous, conico - campanulate, scarcely expanded, obtuse, even, 

 smooth. Stem 10-15 cent. (4-6 in.) long, 2-4 mm. (1-2 lin.) thick, 

 fistulose, attenuated upwards, tense arid straight, polished, smooth,
