Type species – Rubroshiraia bambusae D.Q. Dai & K.D. Hyde, MycoKeys 58: 16 (2019).
Notes – Rubroshiraia was introduced by Dai et al. (2019) based on morphology and phylogeny. The genus has typical morphology of Shiraiaceae, which is large, dark red and fleshy ascostromata, parasitism on bamboo host and similar efficacy of medical treatment (Dai et al. 2019). However, it differs from Shiraia bambusicola in having smaller and darker ascostromata and filiform ascospores, spirally arranged in asci. Dai et al. (2019) provided molecular data of type species, and confirmed it phylogenetically close to Shiraia bambusicola. Production of the ascostromatal metabolites hypocrellin A and B were examined by Dai et al. (2019).
