(Prague) 3: 36 (1839)</p><p>Notes.</p><p>Coryneaceae, typified by Coryneum, represents a both morphologically and phylogenetically distinct lineage within Diaporthales, primarily characterised by the production of transversely distoseptate, brown conidia (Senanayake et al. 2017, 2018; Jiang et al. 2018, 2019; Rathnayaka et al. 2020). To date, three genera have been accepted in Coryneaceae, based on integrated morphological and phylogenetic evidence, viz. Coryneum, Hyaloterminalis and Subellipsoidispora (Tang et al. 2023) . While phylogenetic analyses have placed Talekpea in close relationship with Coryneum (Rathnayaka et al. 2020; Tang et al. 2023), this genus exhibits significant morphological divergence from the three accepted genera. Resolution of its taxonomic status will require additional sampling and more comprehensive studies in the future. Notably, Hyaloterminalis is distinguished from Coryneum, based on its pycnidial conidiomata (Rathnayaka et al. 2020). Subellipsoidispora has been described only from its sexual morph, distinguished from Coryneum by ascomata typically bearing a single peridium (Tang et al. 2023). This disparity in known morphologies highlights the need for further research to fully understand the life histories and evolutionary relationships within Coryneaceae .</p></div>	https://treatment.plazi.org/id/F8AD843BC13B579FA5F5B3DDDC7CCDAF	Public Domain	No known copyright restrictions apply.

The asexual morphs of Coryneum are commonly observed and are predominantly found on tree genera such as Betula, Castanea and Quercus (Senanayake et al. 2017; Jiang et al. 2018, 2019). Species in this genus are characterised by transversely distoseptate, brown conidia (Senanayake et al. 2017). Currently, the delimitation of species within Coryneum relies on a combination of morphological characteristics and molecular phylogenetic analyses, based on ITS, LSU, rpb 2 and tef 1 loci (Jiang et al. 2018, 2019). Nevertheless, the lack of molecular data for many described species remains a constraint for accurate species identification (Jiang et al. 2018, 2019). Species of Coryneum are commonly reported as plant pathogen causing canker diseases and some species are saprobic on decaying wood contributing to nutrient cycling (Senanayake et al. 2017, 2018).</p></div>	https://treatment.plazi.org/id/6C01FA7E1F9559118157FFADAB1AF687	Public Domain	No known copyright restrictions apply.
