The perfect state of Chondropodium pseudotsugae White is shown to be a new species of Durandiella, for which the name D. pseudotsugae is proposed. Maximum growth in culture is obtained on corn meal agar at 15 °C. Apothecia are produced in the spring; the ascospores are forcibly discharged; pycnidia persist throughout the summer and discharge spores only when moistened. The host response of Douglas fir is the production of a "button" of persistent secondary periderm beneath the infected area.
