Cyatheomyces synnematosus has a unique morphology, characterized by macronematous, synnematous conidiophores, which notably distinguishes it from other genera in this family, which typically have solitary, micro- or macronematous, mononematous conidiophores (Crous et al. 2018 a; Hernández-Restrepo et al. 2019; Xu et al. 2024). The morphological characteristics are similar to species in Phaeoisaria and Rhamphoriopsis (Hyde et al. 2018, 2019; Yang et al. 2023). However, phylogenetic analysis showed that Phaeoisaria was placed in Pleurotheciaceae, Pleurotheciales, Sordariomycetes, and Rhamphoriopsis in Rhamphoriaceae, Rhamphoriales, Sordariomycetes (Hyde et al. 2024) . Comparatively, Cyatheomyces is assigned to Muyocopronaceae ( Muyocopronales, Dothideomycetes) based on evidence from morphology and phylogeny.</p></div>	https://treatment.plazi.org/id/568E1450BB665B859D3E9C78F7AEF7FC	Public Domain	No known copyright restrictions apply.

However, these groups are phylogenetically distinct and also differ in some morphological characteristics. Microlepicola guizhouensis differs from the two aforementioned genera in having immersed ascomata with clearly visible epidermal cell composition, ranging from textura angularis to textura prismatica.

However, they are phylogenetically distinct and also differ in the shapes of their ascomata (raised vs. flattened), asci (asci without distinct ocular chambers vs. asci with distinct ocular chambers), and ascospores (ellipsoid to broadly fusiform ascospores with obtuse ends vs. fusiform to inequilateral ascospores with pointed ends). Multigene phylogenetic analysis shows that Pseudopalawaniella woodwardiae forms an independent clade within Muyocopronaceae, sister to Cyatheomyces synnematosus, with good bootstrap support (100 % ML / 1.00 PP, Fig. 1). However, we were unable to compare the morphological characteristics of these two species, as Pseudopalawaniella woodwardiae presents a sexual morph in nature, whereas Cyatheomyces synnematosus exhibits an asexual morph. Attempts were made to culture the asexual morph in Pseudopalawaniella woodwardiae and the sexual morph in Cyatheomyces synnematosus, but these attempts failed. Therefore, there is no morphological evidence to prove that the two species belong to the same genus. Furthermore, a comparison of nucleotide base pairs of LSU, ITS, RPB 2, and tef 1-α between Pseudopalawaniella woodwardiae (HKAS 129705) and Cyatheomyces synnematosus (HKAS 129699) showed 27 / 833 bp (3.2 %, including 3 gaps), 97 / 839 bp (11.6 %, including 42 gaps), 95 / 1079 bp (8.8 %, without gaps), and 45 / 991 bp (4.5 %, without gaps) differences. Hence, to avoid taxonomic confusion, we introduce Pseudopalawaniella as a new genus in Muyocopronaceae ( Muyocopronales). Further morphological investigations, together with more collections and molecular data, are needed to clarify the status of these two genera.</p></div>	https://treatment.plazi.org/id/9AFA7F93602455D09DA9CF58584976AF	Public Domain	No known copyright restrictions apply.

Phylogenetic analysis showed that our three new isolates form a distinct clade within Xenoberkleasmium . The characteristics of these new collections align with the generic concept of Xenoberkleasmium, and therefore, we have transferred them to Xenoberkleasmium .</p><p>Notably, Verma et al. (2019) introduced a new geographical record for Berkleasmium pandani based solely on morphological characteristics. However, based on the photographs and descriptions provided by Verma et al. (2019), we found that the elliptical to globose basal cells attached to the conidia were incorrectly described as conidiogenous cells. We therefore consider that the identification of the specimen (PAN 32722) as Berkleasmium pandani requires reevaluation, and we do not accept this specimen provided by Verma et al. (2019) as a valid record of Berkleasmium pandani .</p></div>	https://treatment.plazi.org/id/6BC8F5DAA4815239BDB2031AABEA5C2A	Public Domain	No known copyright restrictions apply.
