128 THE PLANT WORLD. 



fragments of the veil suggests Hvpholoma, but portions of the 

 veil remain on the stem also which would indicate more clearly 

 Stropharia, since several genera with annulate stems have a num- 

 ber of species in which portions of the veil cling to the margin 

 of tlie pileiis. It is also near the genus Psilocybe, especially to 

 the section in Avhicli there is a rndimentarv veil in the voung 

 plant. J>iit taking all of these things into consideration I believe 

 the species should be located in Stropharia, but with the species 

 name given by Dr. Peck. In this connection a technical de- 

 scription of the species may be given. 



Stroijharia cp'unyces (Peck) Atkinson. 



Plants clustered, often with the bases of several joined. 3-7 

 cm high, pileus :2-6 cm broad, stems 6-15 nun in thickness. 

 Pileus convex to expanded and margin often elevated in age, 

 fleshy, 2-3 mm thick, thin at the margin, dingy white and soft, 

 with a finely floccose surface appearing something like a chamois 

 skin and often with numerous appressed scales. Margin appen- 

 dicnlate with fragments of the veil. Gills adnate to adnexed, 

 slightlv sinuate or rounded, 1-6 mm broad, gravish then dark 

 brown, edge white. Spores blackish with a slight ])urplish 

 tinge, broM'u with purplish tinge under the miscroscope, oval to 

 short oblong or elliptical, smooth, 7-8 x 3.5-4.5 u. Easidia cla- 

 vate, 30-35 x 6-8 ;/, 1-spored. Cystidia clavate to subventrieose, 

 extending above the hymenium and arising from the lower part 

 of the subhymenium, 60-65 x 10-12 ii. Stem fleshy, separating 

 easily from the flesh of the pileus, soft, hollow, even or somewhat 

 enlarged at the base, whitish, fibrous striate, floccose scaly witli 

 a delicate annulus near the base where the margin of the cap 

 separates from the stem in young stage. Parasitic on clusters 

 of Coprinus atramentarius, Ithaca Flats, X. Y., October 9, 1900, 

 C. O. Smith, C. U. Herb., Xo. 5124; lawn near Armory, C. U. 

 campus, October 11, 1901, G. F. A., C. U. Herb., ^o. 7852;

 Sherman. Edible. Taste when fresh exactly like that of Co- 

 prinus atranieiitarius. The host is deformed and prevontod 

 from o])ening fully, but in some specimens the gills an<l ])ileus 

 were well enough developed to permit of identification.
