Type species – Amphirosellinia nigrospora Y.M. Ju, J.D. Rogers & H.M. Hsieh

Notes – Amphirosellinia has rarely erumpent to mostly immersed perithecioid, bipartite stromata and has a close affinity to Rosellinia. The genus has synnematous, geniculosporium-like asexual morphs that produce lacrymoid conidia (Ju et al. 2004). However, Amphirosellinia differs from Rosellinia in having stromata that develop beneath the host epidermis with a thick, carbonized crust. The genus has been identified as a potential antimicrobial agent using A. nigrospora (Nguyen et al. 2018).
