Agaricacese 



Hyphoioma. West Virginia, 1881-1885; Pennsylvania, New Jersey, densely ces- 

 pitose on stumps and roots. October to long after frosts. Mcllvaine. 



Edible. Dr. Taylor, 1893. Dept. of Agr. Rep. No. 5. 



H. sublateritium has many forms. Both Fries and Stevenson indi- 

 cate this as a variable species and my own observation confirms the 

 truth of this. 



This is a very common autumnal species, lasting into the winter. Old 

 authors give it as bitter and very poisonous. I tested it in 1881 and 

 have been eating it, in common with all Hypholomas I have found, ever 

 since. At times it is bitter. I believe this to be due to the passage of 

 larvae through the flesh. Unattacked specimens are slightly saponaceous 

 to the taste while others in the same bunch are bitter.

 Velutini. Pileus silky, etc.

 ram's Creek, 1887, Mcllvaine. 



Var. leiocepti alus B. and Br. (Gr. smooth; Gr. head, from its 

 smooth pileus). Pileus hygrophanous, rugged, smooth except at the 

 margin, where it is fibrillose, pallid as is the stem, whose apex is mealy. 



Densely cespitose, much smaller than the common form, but ap- 

 parently a mere variety, thoirgh a striking one from its smooth but very 

 rugged disk. On old stumps. Stevenson.
