Type species – Halotestudina muriformis Dayarathne & K.D. Hyde Mycosphere 11(1): 69 (2020).
Notes – Halotestudina is a genus described from marine habatits. It differs from other genera in Testudinaceae in having brown muriform ascospores with constriction at each septum. Halotestudina shares similar characters with Muritestudina in having muriform ascospores. However, Muritestudina is distinguished by its hyaline ascospores enclosed in a thick gelatinous sheath and its occurrence in terrestrial habitats (Wanasinghe et al. 2017c). Multi-gene phylogenetic analyses revealed that Halotestudina muriformis formed a separate clade within Testudianace with moderate bootstrap support, sharing a sister relation with Angustospora nilensis (MFLU 15-1511) and Trematosphaeria wegeliniana (CBS 123124). Cultures and sequence data are available for the type species.
