Cortinarius are globally distributed mushrooms, all of whom form mycorrhizae, and are characterized by rust-brown to brownish-red spores. Here, we describe two new species of Cortinarius, C. griseoaurantinus (subgenus Leprocybe) and C. yonganensis (subgenus Dermocybe), from Fujian Province, Southern China. Identification was conducted based on detailed morphological description coupled to molecular phylogenetic analyses of both nuclear ribosomal internal transcribed spacer (ITS) and nuclear ribosomal large subunit (nrLSU) sequences. C. griseoaurantinus is distinguished by its medium-sized basidiomata, bright orange to brownish orange pileus with the disc light to dark brown, and distinctly verrucose basidiospores (5.9) 6.1–6.5–7.5 (8.2) × (4.6) 4.8–5.3–5.9 (6.1). In contrast, C. yonganensis is characterized by its reddish-pink to deep jasper red pileus with a violet-brown conspicuous umbonate at center, margin with violet-brown striate, and punctate, subglobose basidiospores (5.0) 5.3–6.0–6.6 (7.4) × (3.9) 4.1–4.3–4.6 (4.7). Comprehensive morphological descriptions, color photographs of fresh basidiomata, photographs of microscopic characters, and phylogenetic trees are provided.
