Discussion
Type. On Cupressus duclouxiana, Yunnan, Kunming, China, F. L. Tai et al. 8097 (Herbarium, Plant Pathology, National Tsing Hua University, Kunming).
Tai (Farlowia 3: 107. 1947) described this species in English. He knew that it did not agree with Gymnosporangium cunninghamianum but nevertheless referred it to that species. It is herein described as a new species. Tai cites three numbers, 8097, 8162, 8197. I designate 8097 as the type. Tai illustrated two teliospores (Farlowia 3: 137, fig. 8, 1947).
