CLASSIFICATION OF ACARICB 371 



to ashy-purplish <>t first, soon paler, a1 Length cinnamon-brown, 

 edge eroded-crenulate. STEM is cm. long, clavate-thickened at or 

 near the base, narrowed upwards, 5-9 mm. thick above, ap to 20 

 mm. below, spongy-stuffed, usually peronate by thin, white, appress- 

 ril, silky-interwoven, soft universal veil, violaceous above and be- 

 neatfa the veil. CORTINA white. SPORES 6.5-9 s I -5 (rarely LOx 

 5.5), elliptic-oval to uarrow-elliptical, scarcely rough, variable in 

 size. BASIDIA 30x6-7 micr., t-spored. ODOR and TASTE mild. 

 MYCELIUM white. 



Qregarious. Among leaves or in deep humus of hemlock, mixed 

 orfrondosew Is. Throughout the State. August-October. Scarce- 

 ly Infrequent. 



It is possible that this species may be composed ot an aggregation 

 of several forms. One form has more uniform and smaller spores 

 and the surface layer of the pileus becomes subgelatinous in we1 

 weather. I would call this forma pulchripes, since the stem is beau- 

 tifully marked by the violaceous color above the white sheath. Its 

 spores measure 6-7.5x4-5 micr. In all other respects it shows the 

 characteristics of C. alboviolaceus. All forms have the same devel- 

 opment In the young plant, the stem is relatively stout and elavate- 

 subconic, with a more or less helmet-shaped young cap, scarcely 

 broader than the stem, mounted on its apex. The mature Btem is 

 somewhat irregularly ventricose-thickened' sometimes above the 

 base, sometimes truly clavate-bulbous. The color is typically viola- 

 ceous-white bul varies to deeper \ iolaceous in the gills and flesh and 

 the very young button is deeper violet in the interior. The color 

 lades somewhat, bul dried specimens always show the gray or violel 

 tints. I have not been able to distinguish C. malachius Yv.. an 

 European plant, in this region. The nearest relative of C. malachius 

 with us seems to be C. obliquus Pk.

PILEUS 4-10 cm. broad, firm, subhemispherical at first, then 

 broadly convex to expanded, often gibbous, obtuse, not hygrophan- 

 ous, innately silky-tomentose, glabrescent, even, grayish buff, be- 

 coming ochraceous or rusty stained in age. margin at ftrsl incurved, 

 then spreading and whitened by the veil. FLESH thick, compact, 

 pale caesious then whitish, ciu.s adnate ;it first, becoming
