Zhang et al. (2019a) introduced Striatiguttulaceae based on the polyphasic approaches of morphology, phylogeny and divergence time estimates. Their phylogenetic analysis, based on the combined LSU, SSU, tef-1α and rpb2 data, revealed a distinct clade of Striatiguttulaceae within Pleosporales, which comprises two separate subclades, prompting the introduction of two novel genera in this family: Longicorpus and Striatiguttula. Phylogenetically, the family is closely related to Ligninsphaeriaceae and Pseudoastrosphaeriellaceae, but it differs in the morphology of its ascomata and ascospores (Zhang et al. 2016, 2019a). Species in Striatiguttulaceae are saprobic on palm hosts in mangrove habitats. The sexual morph is characterized by immersed, erumpent or superficial, papillate, ostiolate stromata, a several-layered, brown to hyaline peridium, trabeculate pseudoparaphyses, cylindric-clavate, pedicellate asci, and eight fusiform or ellipsoidal, 1–3-septate, striate, hyaline to brown ascospores with paler end cells and a mucilaginous sheath (Zhang et al. 2019a).
Type genus: Striatiguttula S.N. Zhang, K.D. Hyde & Jian K. Liu, MycoKeys 49: 111 (2019).
