Phytotaxa 678 (3): 146-166, DOI: 10.11646/phytotaxa.678.3.1, URL: https://doi.org/10.11646/phytotaxa.678.3.1
394387BCFFBCFFD459FA902EFBD72C10.taxon	etymology	Etymology: — “ cangshanensis ” refers to the Cangshan Mountain, where the holotype was collected. Endophytic in healthy Rhododendron decorum leaves. Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata on PDA, pycnidial, gregarious, globose to pyriform, black, erumpent, exuding grey to black conidial masses. Pycnidial walls 56 – 77 μm wide (x = 66.5 μm, n = 25), comprising several layers of textura angularis cells, outer layers dark brown to black, inner layers pale brown to hyaline. Ostiole single, central, 5 – 8 μm wide (x = 6.5 μm, n = 30). Conidiophores cylindrical to ampulliform, often reduced to conidiogenous cells. Conidiogenous cells 15 – 17 × 4 – 12 μm (x = 16 × 8 μm, n = 30), terminal, arising from the inner layer of the pycnidial wall, subcylindrical or ampulliform, hyaline. Conidia 10 – 12 × 6 – 8 µm (x = 11 × 7 μm, n = 30), solitary, ellipsoidal to obovoid, hyaline, aseptate, guttulate, with a large central guttule when immature, smooth walled, truncate at the base, consisting of an apical appendage. Appendages 7.4 – 8.2 × 1.3 – 1.5 μm (x = 7.8 × 1.4 μm, n = 30), flexuous, unbranched, straight or curved, tapering towards a rounded tip. Culture characteristics: — Colonies growing on PDA were incubated in darkness at 25 ℃ for 14 days, during which they grew about 30 – 50 mm, with a growth rate of 2.1 – 3.6 mm / day. The surface and reverse of colonies are grayish to black, with an irregular edge. Gray to black conidiomata are formed after 14 days on PDA.	en	Huang, Zi-Yang, Shen, Hong-Wei, Su, Xi-Jun, Luo, Zong-Long (2024): Phyllosticta cangshanensis sp. nov., an endophytic fungus from Rhododendron decorum in Cangshan Mountain, Yunnan Province, China.

394387BCFFBCFFD459FA902EFBD72C10.taxon	materials_examined	Material examined: — China, Yunnan Province, Dali City, Cangshan Mountain, 25 ° 50 ′ 44 ″ N, 100 ° 4 ′ 22 ″ E (2753 m), isolated from healthy leaves of R. decorum, March 2024, X. J. Su, B- 44 (KUN-HKAS 136942, holotype), extype living culture, CGMCC 3.27856 = KUNCC 24 - 18304; Cangshan Mountain, 25 ° 50 ′ 44 ″ N, 100 ° 4 ′ 22 ″ E (2753 m), isolated from healthy leaves of R. decorum, March 2024, X. J. Su, B- 48 (KUN-HKAS 136943), living culture, CGMCC 3.27857 = KUNCC 24 - 18306. Notes: — Our two strains, CGMCC 3.27856 and CGMCC 3.27857, grouped and formed a sister clade to P. rhodorae (CBS 901.69), and are located within the P. rhodorae species complex with strong support (100 % ML / 1.00 PP, Fig. 1). There are 88 nucleotides base differences between CGMCC 3.27856 and P. rhodorae (28 / 516 bp in ITS, 3 / 763 bp in LSU, 21 / 215 bp in tef 1 - α, 13 / 202 bp in act, and 23 / 623 bp in gpdh). From a morphological perspective, CGMCC 3.27856 differs from P. rhodorae by its smaller conidia (10 – 12 × 6 – 8 μm vs. 11.5 – 17.5 × 7.5 – 9.5 μm). In addition, our species has apical appendages, but this feature was not observed in P. rhodorae (Davis 1946). Notably, our species and P. rhodorae were isolated from the leaves of Rhododendron species. Based on phylogenetic analyses and morphological characteristics, we establish a new species, P. cangshanensis.	en	Huang, Zi-Yang, Shen, Hong-Wei, Su, Xi-Jun, Luo, Zong-Long (2024): Phyllosticta cangshanensis sp. nov., an endophytic fungus from Rhododendron decorum in Cangshan Mountain, Yunnan Province, China.
