Tubes up to 4mm deep, rarely 8mm near the stem. Pores 1-3mm, angular, often expanded and radially elongated toward the stem; in some specimens the pores join together to form pseudogills with 1-3mm between the pseudogills; pore surface cinnamon to rusty brown. Stem 10-40 x 5-l0mm, central or lateral, expanding toward the pore surface; cinnamon to deep rusty brown; felty to warted with smooth patches in age.

Comment In the past, this fungus has been split into two varieties. Those with the concentric pseudogills were known as
Coltricia montagnei var. greenii Fr., which was also known as Cyclomyces greenii Berk., and the poroid variety, known as Coltricia montagnei Fr. var. montagnei.
