THE GENUS THERRYA

Abstract

The genus Therrya Sacc. & Penz. is shown to include two distinct species, Therrya pini (Alb. & Schw.) von Höhn. and Therrya fuckelii (Rehm) Kujala, which have been considered synonymous. The name Coccomyces strobi is proposed for the organism occurring on Pinus strobus in North America which has been considered synonymous with Therrya pini or referred to under invalid or unpublished binomials.
