Remarks.

Dentocorticium portoricense is easily recognised by its poroid, hydnoid to spinose, dark brown hymenophore and greenish-yellow hymenial surface. Phylogenetically, it is closely related to D. taiwanianum (Fig. 1). See Ryvarden (1982) for description and drawing of this species with synonymy.
