Discussion.

P. hymeniicola is a poorly known species from North America which has sometimes been associated with the S. nivea complex ( P. semipileatus by Lowe (1947, 1966)). Niemelä (1998) studied the type specimen and concluded that the dimitic trama with solid skeletal hyphae does not match with the S. nivea complex. Even though we have observed some specimens of S. nivea with such hyphal structure, they were not observed in North American material. Furthermore, the basidiocarp of the type specimen grew on a dead basidiocarp of another polypore species, unlike any of our studied material of the S. nivea complex. The species would appear to be related to S. stellae and related species ( Incrustoporia ).
