CLASSIFICATION' OF AGARICS 331 



c. cylindripe8 usually occurs in considerable cumbers where 

 found. lis cylindrical stem is ;ii firsl n beautiful pale azure-blue, 

 due to the thin universal veil, which fades and leaves whitish thin 

 patches which sometimes disappear. The species corresponds i«» 

 Fries' species, figured in his unpublished plates at Stockholm and 

 named C. collinitus. i See uotes under C. muci fluus.] Specimens 

 of that species collected in Sweden are in my herbarium and have 

 spores measuring l lis micr. long, much larger than in the American 

 form. I consider thai species, common around Stockholm, as Pries 1 

 original C. collinitus. <>m- species, described above, has violaceous 

 or blue linis just like thai "Hie, and as Fries has described no other 

 species t<> which the Stockholm plants could he referred, the indi- 

 cation is Strong that he considered them C. COllitlitU8. For the 



present the difference in the spore size will he sufficienl to keep 

 <'. cylindripes distinct. The violaceous j;ills, etc., distinguish C. 

 cylindripes from both Fries' and Ricken's conception of C. mucosus, 

 and from the related species of Peck: C. muscigenus Pk., C. splen- 

 didus Pk., and c. elatior pallidifolius Pk.

"PILEUS 3-6 cm. broad, at firsl ovate, then convex, or concave

 with <i separable pellicle, tawny-orange and widely striate on the 

 margin when moist, tawny ami shining when dry. FLESH dingy

This species appears to have the stature id' ('. cylindripes, but 



has Larger spores and hicks the violaceous color entirely. The 



spores of the type specimens ;ire Larger than given by Peck in the 

 Original description. The color Of the pileus is similar to thai of
