202 THE AGARICACEAE OF MICHIGAN 



183. Hygrophorus peckii Atk. 

 Jour, of MycoL, Vol. 8. 1902. 



PILEUS 1-2 cm. lu-oad, fragile, convex-plane, broadly umbilicate 

 or depressed, glutinous when moist, color varying pale yellowish- 

 flesh color, pinkish or vinaeeous-huff, rarely tinged greenish, gla- 

 brous, pellucid-striatulate when moist, fading somewhat on drying. 

 GILLS arcuated ecur rent, distant, rather broad, whitish to pale 

 flesh color, trama of parallel hyphae. STEM 3-8 cm. long, 2-4 mm. 

 thick, slender, equal, very viscid, shining, concolor, rarely greenish 

 at apex, hollow, terete, even. SPORES broadly elliptical, 6-8 x 5 

 micr. ODOR present or absent; taste mild. 



Gregarious or solitary. On the ground, moss, etc., of low, wet 

 woods or swamps of cedar and balsam in northern Michigan, 

 maple and oak woods of the southern part of the State. Isle Roy- 

 ale, Marquette, New Richmond, Ann Arbor, etc. July-August, 

 rarely September. Frequent. 



This is much more common apparently than //. lactus, and may 

 represent an American variety of that species. It differs from H. 

 psitticinus by the form of the pileus; in that species it is obtuse 

 or umbonate, and the green color persists longer and is practically 

 always present in the young plant, while in H. peckii the green 

 tinge is rare. Both these species are very slippery on the stem and 

 cap when fresh or young.
