decorated by whitish flbrillose scales from the cortina. FLE8B 

 thickish on disk, thin on margin, watery to pallid. GILLS adnate 

 then Bubemarginate, broad, close, qoI crowded, violaceous <n / 

 with lavender tinge, soon cinnamon, edge concolor. STEM rather 

 stout, 3-5 cm. long, r> - 1 o mm. thick, equal or nearly so, solid, at flrti 

 violaceous, especially at apex, then Bilky-whitisfa and shining,

 Gregarious or Bnbcaespitose. On naked gronnd in low fr l"--- 



woods. Ann Arbor. October. Infrequent 



This species is based here on the figures of Cooke and those of 

 Fries' unpublished plate at Stockholm. The latter shows a pileus 

 colored like ours and somewhat the same as that of Cooke's flgni 

 but is not "gilvus" as described by Fries in his works. Cooke's 

 figures do not BhOW the violaceous character as do those of Fries. 

 Other authors differ considerably in the application of this name 

 and in the spore-size. The figure of Quelet (in Grevillea, Vol. VIII, 

 PI. 127, Fig. 2) is referred by Maire (Bull. d. 1. Soc. Myc. de France. 

 Vol. 26, p. 28), to G. bicolor Cke. and is not at all our plant. The 

 cortina sometimes leaves a row of spot-like shreds on the margin 

 of the pileus, sometimes it forms a slight aunulus on the Btem, 

 but more often it is entirely evanescent. This species is aear C. 

 castancus, from which it differs by its larger, stouter habit. its 

 slightly smaller spores, but especially by the solid stem. Rick.-n 

 considers if a variety of C. subferruginea, but he evidently had a 

 plant with larger spores.
