420 THE AGARICACEAE OF MICHIGAN 



***Gills at first brownish or fuscous. 

 432. Cortinarius brunneofulvus Fr. 



Epicrisis, 1836-38. 



Illustration : Ricken, Die Blatterpilze, PI. 50, Fig. 4 (as G. brun- 

 neus Fr.). 



PILEUS 3-7 cm. broad, convex, hygrophanous, dark watery-brown, 



glabrous, even, subvirgate on drying, margin white from the veil, 

 declined. FLESH coneolor when moist, thick on disk, scissile. 

 < JILLS adnate then sinuate, distinct, thickish,- broad, subdistant, 

 soon brown to dark umber-cinnamon.. STEM 5-8 cm. long, 10-15 

 mm. thick, narrower upwards from a clavate or bulbous base, solid, 

 brown, longitudinally streaked with paler fibrils, annulate by a dis- 

 tinct whitish band at or bciow the middle, from the whitish, uni- 

 versal veil. SPORES elliptical, distinctly tuberculate, 10-12x6-7 

 micr. ODOR and TASTE slightly of radish. 



Subcaespitose. On the ground in frondose woods. Ann Arbor. 

 September. Infrequent. 



This corresponds to Pic-ken's notion of ('. brunneus. But accord- 

 ing to specimens of G. brunneus collected by myself and others near 

 Stockholm, that species has spores measuring 8-9 x 5-6 micr. and the 

 universal veil is more nearly fuscous than white. It appears as if 

 Ricken had interchanged the two species. In order to compare the 

 two plants I give below the description of the Stockholm G. brun- 

 neus which is a common plant there. Fries says G. bruneofnlvous 

 has the stature of E. cvernius, which does not apply as far as the 

 stem of the latter is concerned. No violet tints are present in our 

 plant.

 Syst. Myc, 1821. 



"PILEUS 5 -X cm. broad, campanulate or somewhat obtusely coni- 

 cal at first, then campanulate-expanded and broadly umbonate, 

 moist, hygrophanous, glabrous on center, umber-brown when moist, 

 fulvous-alutaceous when dry, margin decurved and becoming innate- 

 ly fibrillose. FLESH umber when moist, fading, scissile, thin on 

 margin. ('.ILLS adnate, rather broad, distant to subdistant, thick, 

 dark livid-brown at first, sometimes with an obscure purplish tinge
