Mycologia 



is livid a. The white form, alba, is rarely to be seen. The grayish- 

 mouse-colored variety attains a very large size in the mountains of the 

 coast range. My collection has the pileus hair-brown in color, 10-18 

 cm. broad, and the plants reach 28 cm. high. Scales on the stipe are 

 mouse-gray. 



23. Lepiota clypeolaria Fries. 



In mixed or coniferous woods', Corvallis. November. Commonly 

 found west of the Cascade Mountains. No. 2183. 



24. Lepiota granulosa Fries. 



In mixed woods, Corvallis. October. No. 2033. This species is 

 common throughout western Oregon. 



25. Lepiota pulcherrima sp. nov. 



Pileus 6-12 cm. broad, subhemispheric at first, then convex to quite 

 plane, moderately fleshy, young buttons quite solid, acajon-red to Vandyke 

 red at the center, Venetian- or alizarine-pink on the margin, often fading 

 to a silvery livid-pink in age ; cuticle on margins of older specimens split ; 

 surface appearing velvety because of the innate-pubescence towards the 

 center, nearly glabrous or silky on the margin or squamulose when 

 closely covered by another pileus, becoming slightly appressed-scaly in 

 age due to growth. Margin sterile. Flesh white, rather thin except disk. 

 Gills free, white, close, broad, rounded behind, edges even. Stem 5-10 

 cm. long, 8-12 mm. thick, equal or tapering upward, slightly bulbose, 

 peronate by a thin membrane colored like this pileus about one half to 

 two thirds of the way up to the rather large, flaring, rather fleshy, per- 

 sistent annulus, white within, white to pinkish above the annulus. Spores 

 smooth, white, oblong, 3-4.5 x 5-8 fi, usually uniguttulate. Pleasant 

 flavor. Odor mildly farinaceous. 



Gregarious to caespitose. Growing from a distinct, heavy spawn in 

 needle mould under Pseudotsuga taxifolia. (November to December.) 



This is the most beautiful species of Lepiota with concolorous pileus 

 and booted stem which the writer has ever seen. It is distinctly char- 

 acterized by the rich color and surface of the pileus and the color and 

 peronate character of the stem. It has been found at two stations in 

 this locality and in one of these evidently growing from the same spawn 

 for two seasons in succession. 



Specimens examined : Oregon, Corvallis, /. W. Severy and S. M. 

 Zeller 2123, type (in Zeller Herb. 2123, N. Y. Bot. Gard. Herb, and O. 

 A. C. Herb. 3390) ; S. M. Zeller 21 71, 2172 and C. C. Epling 72 (all in 

 Zeller Herb.). 



26. Lepiota rubrotinctoides Murrill. 



In coniferous woods, Corvallis. This species is very common from 

 October to December and lasts for about four weeks after the rains begin. 

 This often would be mistaken for L. rubrotincta Pk. by eastern collectors 

 but it differs in the darker almost black disk and the spores average con- 

 siderably smaller. The stipe often has rosy tints especially below the 

 annulus. 



27. Armillaria albolanaripes Atkinson. 



On ground in coniferous woods, Corvallis. October and November. 

 Common. No. 213 1. This species has been reported from Oregon and 

 California, but the writer has collected it as far north as Seattle, Wash- 

 ington.
