THE AGARICACEAE OF MICHIGAN 



This species differs from the yellow-gilled group of the preceding 

 section in the obsolete or absent sheath on the stem. Ricken has 

 described and figured a species under this name with a minutely 

 squarrose-scaly pileus and a differently shaped stem. Our plant 

 seems to fit the Friesian species more closely than his, and the 

 spores agree with those of specimens from Stockholm. Its colors 

 and shapely form make it an attractive species. It does not appear 

 to occiir often. The colors become deeper in age. 



385. Cortinarius autumnalis Pk. 



N. Y. State Cab. Rep. 23, 1872. 



Illustration: Hard, Mushrooms, Fig. 236, p. 294, 1908. 



"PILEUS 5-9 cm. broad, convex to expanded, dull rusty-yellow, 

 variegated or streaked with innate ferruginous fibrils. GILLS 

 moderately broad, close, with a wide, shallow emargination, at 

 length rusty-yellow. STEM 6-10 cm. long, 10-12 mm. thick, equal 

 above the oval bulb, pale rusty-yellow, solid, firm. FLESH white." 

 SPORES elliptical, slightly rough, 7.5-9x4-5 micr. 

 "Pine woods. Bethlehem, Pennsylvania. November." 

 This is a somewhat confusing species. Including the type. I 

 have seen specimens from several sources so named, but have not 

 been able to refer any of my collections to it. The descrip- 

 tion as given by Peck is incomplete and although I have amended 

 it so far as the type-specimens and an accompanying drawing 

 permits, it remains uncertain as to the color of the young gills. 

 The specimens of Peck show that it changes markedly towards 

 rusty colors in age. The photograph of Hard represents a plant 

 which appears familiar but as he omits a description of his own 

 no certainty can be felt about it. 



386. Cortinarius catskillensis Pk. 

 N. Y. State Cab. Rep. 23, 1872. 



"PILEUS 5-8 cm. broad, convex or subcampanulate, then sub- 

 expanded, even, grayish-drab, (pale ferruginous?) variegated with 

 minute, scattered white fibrils. GILLS deeply emarginate, close 

 to subdistant, rather broad, watery cinnamon at first, becom- 

 ing darker with age. STEM 6-9 cm. long, 10-20 mm.- thick,
