Pathogenic on twigs and branches of Machilus leptophylla. Sexual morph: Pseudostromata immersed, slightly erumpent. Ectostromatic disc ovoid to ellipsoid, yellowish to dark grey. Central column beneath the disc more or less conical. Stromatic zones lacking. Perithecia conical, surrounding the ectostromatic disc. Ostiole single, dark grey to black. Paraphyses deliquescent. Asci 8-spored, apical ring. Ascospores 2–3-seriate, hyaline, fusoid, bicellular, multiguttulate. Asexual morph: Undetermined (adapted from Fan et al. 2018, Senanayake et al. 2018).

Notes – Diaporthostomataceae was introduced by Fan et al. (2018) to accommodate the monophyletic genus Diaporthostoma. The species of Diaporthostomataceae are characterized by conical and separate perithecia and bicellular, fusoid, straight to curved ascospores with a median septum (Fan et al. 2018, Senanayake et al. 2018). Multi-gene phylogenetic analysis revealed that the family is monophyletic and sister to Diaporthosporellaceae (Senanayake et al. 2018). Diaporthostomataceae species are morphologically distinct from Diaporthosporellaceae, in having discrete perithecia and fusoid, straight to curved ascospores with a median septum (Fan et al. 2018, Yang et al. 2018d). Diaporthostoma machili is the only species in Diaporthostomataceae and it was collected on twigs and branches of Machilus leptophylla from China. Sequence data are available in GenBank (Fan et al. 2018).

Type species: Diaporthostoma X.L. Fan & C.M. Tian, in Fan, Bezerra, Tian & Crous, Persoonia 40: 124 (2018).
