Capnodium was introduced by Montagne (1849) as the type genus of Capnodiaceae . Species of this genus are one of the most common sooty molds with diverse host range in tropical and subtropical regions worldwide ( Chomnunti et al. 2011 , 2014 ; Hongsanan et al. 2015 , 2020 ). These species are frequently found co-occurring with other species and share morphological similarities. The sexual and asexual morphs of this genus can be found together on the same substrate. One hundred fifty (150) epithets of Capnodium species listed in Index Fungorum (2023) . Nevertheless, sequence data of only 12 species are available in GenBank. In this study, we validate Capnodium paracoartatum , and provide newly obtained sequence data for Ca. coartatum and Ca. gamsii , both of which are new host records.
