CLASSIFICATION OF AGARIl 



containing the yellow coloring matter; these are 30-35x20-25 tnicr. 

 in diam. The hyphae of the uiti trama converge and are long and 

 cylindrical. Prom /'. leoninus this form te separated bj it- yellow 

 stem and rngulose pileus; the rugosity, however, maj !"• aln 

 lacking al times. Variations occur approaching other Bpecies, 1 i k • * 

 /'. chrysophaeus, P. flavafuligincus and P. leoninus, and such 

 often difficult to place. I have never seen /'. chrysophaeus Fr. but 

 include ii in the key, as it has been reported bj Longyear.

PILEUS 2-5 cm. broad, campanulate-convex, subumbonate, not 

 rugulose, glabrous, moist, yellow, striate on margin, GILLS free, 



moderately broad, close, white then deep llesli color. STEM 5-7 Cm. 



long, 2-5 mm. thick, equal or enlarged below, striatulate, glabrous, 

 solid, pellucid-white or whitish. SI'OKKS subglobose to oval 

 elliptical, 6-7x5 micr., smooth, dull rose-colored. CYSTIDLA 

 about 00 micr. long. Fusiform, subacuminate above, not abundant, 

 not horned. 



Solitary. On rotten wood, [nfrequenl in the hemlock fore* 

 of the north. Xegaunee, etc. 



A form was found with the surface of the pileus minutely velvety. 

 Patouillard says the surface is glabrous, composed of long Blender 

 hyphae. In this respeel the form differs markedly from /'. admira- 

 bilis Pk. 



Entoloma I'r. 

 i from the Creek. ent08, inside; ami lomo, the holder of ;i t'ol 



Pink-spored. "Without volva or annulus. Stem fleshy <>r flbro 

 not cartilaginous, soft, confluent with thi pileus. Gills adnaU 

 adnexed, emarginate >>v sinuate. Spores angular, rarely rounded. 



Cystidia rarely present in a few species. 



Mostly large, soft, pntrescenl mushrooms; terrestrial, frequent 

 in rainy weather; some of the species are poisonous. A difficult 

 genus to study.
