The genus Thelephora, as defined by Fries (Syst. Myc. 1:428. 1821), includes many of the present members of the group and many more which are now placed in other genera. Citing Ehrhart, Crypt. Exsic. No. 178. 1785, as his basis, Fries defined the genus as composed of those fungi having a compact, homogeneous pileus which is coriaceous and persistent. T. terrestris Ehrh. is designated the type species. Thelephora, as envisioned by Fries, included five "tribes" in the genus proper. In addition he listed Stereum, Phylacteria and Leiostroma as subgenera. Some of these subgroups had been treated as genera by earlier authors, and some of them have since been regarded as worthy of generic ranking.
