The specific epithet "cranhamii" chosen in honor of Gerald Cranham in recognition of his contribution of a number of Vancouver Island plant fossils to the University of Alberta for study.
Cryptodidymosphaerites princetonensis and Palaeoserenomyces allenbyensis were the first fossil fungi to be described from British Columbia, known only from the Early Eocene Allenby Formation near Princeton, B.C.
[1] The specimen was studied by cutting the calcareous nodule into slices with a rock saw and using the cellulose acetate peel technique to create slides that were examined under stereo microscope.
[1] Quatsinoporites is placed in Hymenochaetaceae based on the structure of the poroid hymenophore, the presence of setae and monomitic hyphal system lacking clamp connections.
