Notes – Allocryptovalsa was introduced by Senwanna et al. (2017) to accommodate
A. polyspora and two combined species: A. cryptovalsoidea, which was transferred from Eutypella and Allocryptovalsa rabenhorstii, which was transferred from Cryptovalsa. The genus is characterised by stromata immersed in host tissues, polysporous asci and allantoid ascospores. However, the combined species A. cryptovalsoidea is invalid according to the basionym of this species, Eutypella cryptovalsoidea is invalid because Trouillas et al. (2011) designated holotype with three collections when they introduced E. cryptovalsoidea. Therefore, the current status of Allocryptovalsa cryptovalsoidea is further needed to be resolved. In this study, we introduce a new species Allocryptovalsa truncata based on morphology and phylogeny support.

Type species: Allocryptovalsa polyspora Senwanna, Phookamsak & K.D. Hyde, in Senwanna, Phookamsak, Doilom, Hyde & Cheewangkoon, Mycosphere 8(10): 1840 (2017).

Other accepted species: Species Fungorum – search Allocryptovalsa.
