However, pairwise sequence comparison revealed that E. paris (GZCC 25-27590) and Ca. faginea (CPC 45667) show 38 / 471 bp differences in ITS (8.1 %, including five gaps) and 11 / 863 bp differences in LSU (1.3 %, including one gap). In addition, our isolate (GZCC 25-27590) differs from Ch. canovae (CBS 150.58) by 33 / 498 bp (6.6 %, including five gaps) in ITS and 10 / 847 bp (1.2 %, without gaps) in LSU. Morphologically, E. paris (GZAAS 25-0781) can be distinguished from Ca. faginea (HPC 4129) by its conidiogenous cells, which are micronematous and cylindrical, whereas those of Ca. faginea are monophialidic and subcylindrical to subulate, as well as by its conidia, which are fusiform to lageniform or ellipsoidal, in contrast to the hyaline to olivaceous, obovoid conidia of Ca. faginea (Visagie et al. 2024). Moreover, Vu et al. (2019) provided molecular data for Chaetopsis canovae; however, no detailed morphological description of the species was provided. However, Elliptolagenoidisporium paris differs from the type species of Chaetopsis in having holoblastic conidiogenous cells (vs. polyphialidic) and fusiform to lageniform or ellipsoidal conidia (vs. cylindrical) (DiCosmo et al. 1983). Therefore, based on stable, independent branching and incompatible morphological combinations, we propose that our collections (GZCC 25-27590 and GZCC 25-27591) represent a new genus, Elliptolagenoidisporium, to accommodate the new species E. paris .</p></div>	https://treatment.plazi.org/id/107503E18D785425834DAC6E5CDB9275	Public Domain	No known copyright restrictions apply.

Phylogenetic analyses further indicate that Elliptolagenoidisporium forms a well-supported, distinct subclade within Lachnaceae, corroborating its recognition as a separate genus. Based on both molecular evidence and its distinctive fusiform, lageniform to ellipsoidal conidial morphology, we herein establish the genus Elliptolagenoidisporium and introduce a novel species, E. paris, which is designated as the type species.</p></div>	https://treatment.plazi.org/id/978AB6C131DD556DBA88C7E56EDDC947	Public Domain	No known copyright restrictions apply.
