"PILEUS 3-6 cm. broad, convex then convex-plane, quite thick, 

 with separable, viscid pellicle, glabrous, even, violaceous-blue, 

 tinged ochraceous on dish-, sometimes entirely ochraceous-yellow, 

 not hygrophanous, margin ;ii first incurved pubescent and white, 

 then spreading and violaceous. FLESH j><il< violaceous-blue, 

 especially under the cuticle, then whitish, ;ii Length ochraceous 

 stained. GILLS arcuate, then plane or slightly ventricose, attenu- 

 ate in front, pounded behind, thin, broad, rather broadly adnate, 

 violet -amethyst or violet-blue ai "first, then rusty-brown, edge ser- 

 ratulate. STEM 3-5 cm. Long, LO nun. thick, cylindric-conic, with 

 a marginate bulb, fibrous-fleshy, dry. silky-fibrillose, violaceous-blue 

 to amethyst-blue, bulb while solid. CORTINA violaceous at first. 

 Universal veil rapidly evanescent. SPOKES 12-14x6-7 niier.. 8UD- 



amygdaliform, elliptic tuberculate. ODOE feeble, like thai of C. 

 purpurascens. TASTE mild or slightly bitterish." 



The description lias been adopted from that of Prof. Main- (Bull, 

 de la Sue. Myc. de France, Vol. 27, p. 124, L911). In America I 

 have seen specimens of this species only from Tennessee. The 

 species stands out from the segregates of the old species as ii was 

 variously interpreted, by its large Bpores. In specimens from 

 Sweden. 1 find the same sized spores. In size, color of the young 

 gills and in stature it is much like C. calochrous. Cooke's figures 

 (111., PL 721) and Gillet's figures (Champignons de France, No. 

 *J()S) are referred by Ma ire to G. caesiocyaneus, which they Illus- 

 trate fairly well. As Fries did not give spore-measurements, I pre 



fer to follow the decision reached by Main' after he had compared 

 the species which occurs near Stockholm, with those of France. 

 Our American references to this plant must be considered as usual- 

 ly, if not always, based on collections of C. caesiocyaneus, 0. michy 

 ganensis or perhaps C calochrous. It is possible that a number of 

 intermediate forms also occur as I have some collections which 

 apparently support such a conclusion.
