723772101039FFF2DEB9FF6D8E5241A3.taxon	discussion	Notes: Our collections exhibit distinct morphological characteristics, having acrogenous, obclavate, elongated, and distoseptate conidia, which are not found in any known members of the family Herpotrichiellaceae. Generally, herpotrichiellaceous hyphomycetes comprises black yeasts producing holoblastic, aseptate or septate conidia from small pegs on conidiophores, often in chains with annellidic features and occasional fusion or bending (Müller et al. 1987; Untereiner et al. 1995; Tian et al. 2021), or other forms with short or inconspicuous conidiophores bearing oval, muriform conidia (Tian et al. 2016; Dong et al. 2018). However, the morphological characters of our collections resemble species of Distoseptispora, Sporidesmium (Su et al. 2016), and Linkosia (Wu & Diao 2022) in Sordariomycetes, and Corynespora (Ma et al. 2008) and Sporidesmiella (Ma et al. 2012) in Dothideomycetes, all of which share acrogenous, obclavate, elongated, distoseptate conidia.	en	Madhushan, Asanka, Ding, Peng-Cheng, Maharachchikumbura, Sajeewa S.

723772101039FFF2DEB9FC7589184A5F.taxon	discussion	Notes: The phylogenetic tree showed that our collections formed a distinct clade, sister to the ex-type strains of Veronaea compacta CBS 268.75, V. japonica CBS 776.83, and V. aquatica JAUCC 2549, with 100 % ML bootstrap support and a 1.00 BYPP value (Figure 1). The BLASTn analysis revealed that nucleotides of our isolate differs from V. compacta (CBS 268.75) by 9.73 % (538 / 596, gaps: 13 / 596) variations in ITS, and 1.41 % (771 / 782, gaps: 1 / 782) variations in LSU, differs from V. japonica (CBS 776.83) by 9.23 % (551 / 607, gaps: 11 / 607) variations in ITS, and 2.00 % (784 / 800, gaps: 1 / 800) variations in LSU, differs from V. aquatica (JAUCC 2549) by 10.27 % (498 / 555, gaps: 14 / 555) variations in ITS, 1.70 % (808 / 822, gaps: 1 / 822) variations in LSU, and 11.05 % (346 / 389, gaps: 8 / 389) variations in tub 2. Morphologically, Eurodistus differs significantly from the genus Veronaea. Species of Veronaea have polyblastic, pale brown conidiogenous cells and pale brown to brown, septate conidia (Arzanlou et al. 2007, Chandrasiri et al. 2021; Su et al. 2023), whereas Eurodistus species possess monoblastic, dark brown conidiogenous cells and thick-walled, distoseptate, obclavate conidia that are dark brown to black. Based on the variations in nucleic acid sequences and the morphological distinctions, we group our collections as a novel genus within Herpotrichiellaceae.	en	Madhushan, Asanka, Ding, Peng-Cheng, Maharachchikumbura, Sajeewa S.
