310 THE AGARICACEAE OF MICHIGAN 



303. Pholiota confragosa Fr. 



Epicrisis, 1836-38. 



Illustration: Fries Icones, PL 105 (3). 



Harper, Wis. Acad. Sci. Trans., Vol. 17, PL 41, D. & E. (small 

 plants). 



PILE US 2-6 cm. broad, convex-plane, obtuse, ground-color almost 

 brick-red, or vinaceous-cinnamon when moist, dotted with a white 

 flocculose coating easily rubbed off and which disappears with age, 

 hygrophanous, pale whitish-tan when dry, margin striate when 

 moist. FLESH thin, fragile. GILLS adnate, crowded, narrow, 

 vinaceous-fawn color (Kidg.). STEM 3-8 cm. long, 2-4 mm. thick, 

 equal, stuffed to hollow, flexuous, rufous, silky-fibrillose. AN- 

 NULUS apical, membranous, persistent, white below. SPORES 

 6-7x4-5 micr., even, brown. ODOR and TASTE mild. Northern 

 Michigan. August-September. Infrequent. 



The stem is said to be peronate in the young plant, with a fibrillose 

 white coating which terminates in a spreading membranous ring; 

 with age the ring collapses and the stem is merely fibrillose while 

 the cap is denuded. The rufous color of all parts makes it easy to 

 recognize; in dry plants the color of the cap and stem becomes 

 cinnamon or paler, and of the gills darker.
