| Abstract: | Two new species of Cudonia found from the subalpine regions of the eastern Himalayas and the Hengduan Mountains were described and illustrated based on morphological features and previously published DNA sequence data. Cudonia claviformis has a bright yellow, clavate ascigerous portion and a whitish to brownish, glabrous stipe, while C. furfuracea has a bright yellow, capitate ascigerous head often covered with a well-developed brownish membrane, a dirty white to brownish, furfuraceous stipe. Both species were associated with mosses under dwarf shrubs of Rhododendron and Salix. |
