12B1AEFB6E3E5149989BA3F6B2FDB481.taxon	description	Description. Spermogonia: unknown. Aecia golden, produced on the abaxial leaf surface, hypophyllous, and 2.5 - 3.5 mm diam, subglobose to globose, powdery, 2.5 - 3.5 mm diam. Aeciospores produced in basipetal succession, subglobose, 14 - 24 x 10 - 23 µm (mean 19 x 16 μm, n = 30), bright yellow contents, thick-walled, 1.0 - 4.0 µm, colorless, echinulate; paraphyses clavate, not or weakly incurved, 38 - 61 μm long, thick-walled, wall 2.0 - 2.5 μm thick. Telia hypophyllous, scattered, 0.3 - 0.5 mm diam, chocolate-brown. Teliospores ellipsoid to cylindrical, 3 - 5 celled, constricted at the septa, bright orange, chocolate-brown to gray-brown, 29 - 74 x 14 - 37 µm (mean 50 x 25 μm, n = 30), thick-walled, wall 1.8 - 3.5 μm thick, colorless to chocolate-brown; pedicels not swollen at the base, 8 - 34 μm long, colorless. Uredinia formed on circular lesions on both sides of the leaves, powdery, yellow distinct, hypophyllous scattered, nearly oval, surrounded by host epidermis, 0.5 - 1.0 mm diam. Urediniospores: uredo-type, subglobose to oval, produced in basipetal succession, golden, or bright-yellow, 19 - 27 x 15 - 25 µm (mean 23 x 20 μm, n = 30), thick-walled, wall 0.8 - 1.5 µm thick, colorless, densely and minutely echinulate. Rust diseases symptoms: The golden and powdery aecia were first produced on the underside of leaves. Then, scattered uredinia were formed, orange-colored and forming small round spots on the leaves. Chocolate-brown telia were produced on the leaf remnants (Fig. 4).	en	Sun, Jing-E, Zhang, Qian, Luo, Wen-Mei, Yang, Yuan-Qiao, An, Hua-Ming, Wang, Yong (2022): Four new Phragmidium (Phragmidiaceae, Pucciniomycetes) species from Rosaceae plants in Guizhou Province of China.
