Sesia hirsuta Murrill, Jour. Myc. g: 88. 1903. 
This species is very abundant in the north temperate zone on 
logs, stumps and various other decaying wood of pine, fir, spruce, 
hemlock, juniper and other coniferous trees. It varies consider- 
ably in its wide range. In the higher regions of Colorado and 
adjoining states, for example, it is large and coarse and almost 
shaggy ; while in the southeastern states, on the other hand, it is 
thinner and less densely hirsute than the typical European form, 
with more delicate, easily lacerated gills and a somewhat dif- 
ferently colored surface. The latter form was described from South 
Carolina by Berkeley and Curtis as Lenzites rhabarbarina, but I 
Cannot distinguish it specifically from many of the typical speci- 
mens of S. hzrsuta. It has been quite frequently collected in the 
South by Earle, Langlois, Britton, Schrenk and others. Another 
form, called var. porosa by Peck, is very distinct and would con- 
Stitute a good species if it could be proven to be constant. In one 
instance Peck found a number of specimens on a single pine trunk 
that were all alike poroid. Further observation might establish a 
definite form found sometimes alone and sometimes growing with 
€ species under consideration.

this Study the following are listed to show the range of the species :
