only apparent decurrent. The present species should be compared 

 with Omphalia xantJiophyUa B. & C. which is represented in the 

 Curtis Herbarium by two plants from S. C. (Ravenel). I couJd get 

 no good spores from them. 



1421. On rotting wood by Bowlin's Creek, October 26, 1914. 



1774. On a very rotten pine log half way flown Lone Pine Hill, September 14, 



1915. 

 3781. On pine logs in woods, November 20, 1919. Largest cap 9.8 cm. broad. 



Gills golden, cap squamulose.

Plates 1, 29 and 33 



Cap 2-5.5 cm. broad, convex on margin, the center broadly umbil- 

 icate; smooth, not viscid, strongly hygrophanous, not striate, deep 

 brown, sayal brown of Ridgway when not water-logged, the margin 

 becoming a darker coffee color. Flesh paler, thin (1.5 mm.), elastic, 

 fibrous and toughish ; odor and taste strongly farinaceous. 



Gills close, decurrent, arcuate, 5 mm. broad, margin even, venose 

 connected, color of cap, with a faint or distant lavender tint and a 

 pale sheen. 



Stem long, up to 9 cm., enlarged downward, flattened or irreg- 

 ular, about 5-8 mm. thick above, color of cap above but white below 

 with mycelium and with white silky lines from superficial fibers 

 except at the minutely pulverulent tip ; texture tough and fibrous, 

 stuffed with white fibers, dark near surface. 



Spores (of No. 4934) faintly pinkish-lavender on a heavy print, 

 smooth, elliptic, very granular when first shed but soon showing a 

 very large oil drop, 4.2-6.2 x 9-12.2^. Basidia 5.5-7.4/x thick, clavate, 

 4-spored. Hymenium 40-45/x thick. Context of gills rather close, 

 the threads about 4.5-5. S^u, thick. Scattered rather sparsely among 

 the normal basidia are cells of the same size and shape, but peculiar 

 in having two longer and unequal projections without spores; the 

 longer projections about 14^ long, the shorter about 11/ui. If ab- 

 normal basidia, their regularity is remarkable. 



Very rare in Chapel Hill and apparently occurring only in late 

 fall or winter. According to Ricken it appears in Germany only 

 after frost.
