synonymous.

Pyropotyporus LinTEus (Berk. & Curt.) Murrill, Bull. Torrey 
Club 30: 119. 1903. The following notes, mostly made in 
the field, refer more particularly to the Jalapa collection: 
Young, growing specimens from one to three years old. Ap- 
planate, broadly sessile, slightly flexible, sulcate-zonate, vil- 
lose-tomentose, castaneous with a fulvous tint, margin sterile, 
obtuse, melleous; context zonate, melleous, bounded above 
by a dark, horny layer; hymenium umbrinous with a grayish 
tint, tubes invisible to the unaided eye, fulvous-chestnut 
within; spores globose, deep-ferruginous, copious, 44; cystidia 
cuspidate, dark-fulvous, 60-120 X 10-20u. An interesting 
feature of this species is the appearance under a pocket lens 
of numerous large, brown, pointed cystidia on the broken 
surfaces of the young context.
