Abstract: Labivalidus jianchuanensis (C. L. Hou & M. Piepenbr.) Lan Zhuo & C. L. Hou comb. nov. Fig. 19 Lophodermium jianchuanense C. L. Hou & M. Piepenbr., Can. J. Bot. 83 (1): 40. 2005. Basionym. Type. CHINA, Yunnan Province, Jianchuan, Laojunshan, alt. ca. 3400 m, on Juniperus formosana Hayata (Cupressaceae), 25 Jul. 2001, C. L. Hou, M. Piepenbring, Z. L. Yang, & R. Kirschner 104 (HMAS, holotype). Specimens examined. CHINA, Yunnan Province, Lijiang, Laojunshan, 26.6319°N, 99.7252°E, alt. ca. 3855 m, on needles and twigs of Juniperus squamata (Cupressaceae), 21 Jun. 2021, C. L. Hou, M. J. Guo, and H. Zhou, HOU 1781 B (BJTC 2021092); 26.6314°N, 99.7247°E, alt. ca. 3850 m, on needles and twigs of J. squamata, 21 Jun. 2021, C. L. Hou, M. J. Guo, and H. Zhou, HOU 1815 A (BJTC 2021126); 26.6425°N, 99.7678°E, alt. ca. 3500 m, on needles and twigs of J. squamata, 17 Aug. 2023, C. L. Hou, L. Zhuo, and S. Y. Zhao, HOU 2023 (BJTC 2023153); 26.6425°N, 99.7678°E, alt. ca. 3500 m, on needles and twigs of J. squamata, 17 Aug. 2023, C. L. Hou, L. Zhuo, and S. Y. Zhao, HOU 2024 (BJTC 2023154). Notes. Hou et al. (2005) described Lophodermium jianchuanense on Juniperus formosana in the genus Lophodermium. In the phylogenetic tree, the molecular sequences of Lo. jianchuanense form a clade sister to La. cunninghamiae and distant from Lo. arundinaceum, the type species of Lophodermium. Based on this phylogenetic position and morphological similarity, we transfer Lo. jianchuanense to the genus Labivalidus, the epithet has been adjusted to agree with the gender of the new genus name.
