Typification: CHINA. Hunan Province, Dong’an County, in broad-leaved forest, 14 September 2010, Zuo-Hong Chen, Ping Zhang, MHHNU 30649.
Etymology: Named after the species morphologically similar to Cortinarius salor, and the geographical distribution range of China.
Description: Pileus 10–30 mm, hemispherical at first, then convex with a low umbo to plane, violaceous (16A2-16A4) to bluish violet (17A4-17B4) and the colour is deep in the centre at first, becoming violet white (16A2-17A3) to yellow brown (4B5-4C7), surface glutinous. Lamellae adnexed; moderately crowded, violaceous (16A1-16A2) to bluish violet (17A2-17B2), later brown (5B4-5C7), edge usually incurved. Stipe 40–70 mm long, 4–10 mm thick, cylindrical to clavate, whitish to lilac (16A2-17A3) with fibrillose at the apex, surface covered bluish violet (17A4-17B4) universal veil, basal mycelium white (−A1), solid initially, then hollow. Universal veil glutinous, bluish violet (17A4-17B4). Context violet (16A2-17A2) at the pileus, later greyish violet (17B2) to white (−A1). Odour indistinct.
Basidiospores 7.4–9.0 × 6.0–7.7 µm, Q = 1.07–1.38, Xav. = 8.2–8.3 × 6.6–7.0 µm, Qav. = 1.19–1.27, subglobose to broadly ellipsoid, coarsely verrucose.

Zhejiang Province, Lishui City, Qingyuan County, Baishanzu National Park, in mixed forest, 27°44′14″ N, 119°10′49″ E, 13 August 2023, Yong Zhou, HMJAU 58971.
Notes: Cortinarius sinosalor is characterised by glutinous basidiomata, violaceous to bluish violet pileus, bluish violet universal veil, subglobose to broadly ellipsoid basidiospores, on average 8.2–8.3 × 6.6–7.0 µm. The ITS of MHHNU 8572, MHHNU 30649, and HMJAU 58971 differs in the type sequence by three indels and 4–7 substitutions, but the morphological characteristics of these specimens are consistent with the other specimens. This species is easily confused with other species in sect. Delibuti in morphology. However, the ITS sequences of C. sinosalor differed from those of the other species in sect. Delibuti by at least 40 substitutions and indel positions and formed well-defined species clustered with C. fibrillososalor, C. subtropicus, and C. tibeticisalor in the phylogenetic tree.
