Surface with appressed fibrils, faintly zonate with raised zones. Con- 

 text white. Pores large, rigid, lacerate, irregular. Hymenium with 

 numerous hyaline, projecting, smooth, thin-walled hyphae.

 recognized from the published description, but I am satisfied from 

 my notes and photographs of type at Leiden it is the same as this.
