H. olivaceus . The spores of H. litacinus , Tub, are sometimes 
similarly shaped, but not typically, a point which requires 
strict attention in this genus. (B. and Br.)

Distinguished by its bright, permanently yellow hymenium, 
and smooth, papillate, very variable, often triangular spores. 
The tint varies according to the quantity of spores. Some 
specimens have but little scent, others, especially the larger 
ones, are powerfully foetid. (M. J. B.)
