Common and variable. The pileus is usually olivaceous 
or yellowish-brown, but it may be reddish-brown or tawny- 
red. When it cracks the chinks become yellow. The stem 
is often attenuated downwards, but it is not always ribbed 
or sulcate. In one form it is marked with slight anastomos- 
ing lines which form broad reticulations as in B. lanatus 
Rost. In another form which grows on much decayed 
wood or stumps the pileus is dark-brown.. These may be 
distinct species. According to Johnson, wounds of the 
flesh sometimes become reddish, and according to Palmer, 
the ‘flesh tubes and stem change to blue wherever bruised 
or cut,” but I have not been able to verify these statements. 
The species as I understand it, may be distinguished from 
its near relative, B. chrysenteron, by its paler flesh, the 
clearer yellow tubes not changing to blue where wounded, 
and by the chinks of the pileus becoming yellow. The 
spores of the European plant have been described as 
yellowish-brown and as hyaline or very pale-yellow. Those 
of the American plant, when shed on white paper, appear 
to me to be ochraceous-brown. The species is recorded 
edible by Cordier, Curtis and Palmer. Gillet says it is only 
medium in quality.
