Dothiorella Sacc.

Notes.

Dothiorella ( Botryosphaeriaceae Theiss. & Syd.) was introduced by Saccardo (1880) with D. pyrenophora Berk. ex Sacc. as the type species. Dothiorella has 422 epithets listed in Index Fungorum (2024); however, only 59 species have available molecular data in GenBank. The members of Dothiorella can be found in a wide range of hosts, and taxa exist as endophytes, pathogens, and saprobes (Phillips et al. 2013; Dissanayake et al. 2016; Rathnayaka et al. 2022). The sexual morph of Dothiorella is characterized by ascospores that are hyaline to yellowish brown when immature and later become brown, and 1 - or 2 - septate and asexual morph is characterized by conidia that are initially hyaline and aseptate, later becoming brown and 1 - septate, often attached to conidiogenous cells (Rathnayaka et al. 2022; Senanayake et al. 2023). In this study, we introduced one new species ( D. macadamiae) in Dothiorella, which was isolated from the macadamia tree in Thailand. Additionally, our collection is the first report of Dothiorella species associated with macadamia.
