Abstract: Tryblidiopsis P. Karst., Bidr. Känn. Finl. Nat. Folk 19: 262. 1871. Type. Tryblidiopsis pinastri (Pers.) P. Karst., Bidr. Känn. Finl. Nat. Folk 19: 262. 1871. Sexual morph. Ascomata scattered to clustered, circular, stalked, black, opening by irregular splits. Covering stroma formed by dark brown (# 2 b 180 b) to black (# 000000), thick-walled angular cells. Basal Covering stroma usually absent. Internal matrix of Covering stroma well developed, formed by hyaline, branched, septate hyphae embedded in gelatinous matrix, filled or not filled with crystals. Subhymenium consisting of textura intricata. Paraphyses filiform, branched or not branched, with slightly swollen tips. Asci ripening sequentially, cylindrical to clavate, thin-walled, J –, 8 - spored or 4 - spored. Ascospores 0–6 septate, filiform, fusiform to clavate, hyaline, covered by a gelatinous sheath (Description based on Livsey and Minter 1994). Notes. Livsey and Minter (1994) reviewed the generic concept, and considered Tryblidiopsis to be a monotypic genus. Tryblidiopsis magnesii Tanney & Seifert, Try. sichuanensis S. Wang, P. F. Cannon & C. L. Hou, and Try. sinensis S. Wang, P. F. Cannon & C. L. Hou have been described subsequently (Wang et al. 2014 b; Tanney and Seifert 2019). These species all have stalked ascomata, grow on Picea spp., and have ascospores that are fusiform to clavate, septate, with a thick gelatinous sheath. In the present study, three new species are added to this genus based on morphological analyses, host substratum, and phylogenetic data (Clade 2, Fig. 1).
