In this study, we assigned the new species Erysiphe clematidis for our collections on genus Clematis based on the obvious morphological differences. The appendages of E. clematidis are significantly shorter than those of E. aquilegiae var. aquilegiae [0.7–8 vs. (1 –) 3–12 times as long as the chasmothecial diam.], and the color of their appendages also differs: the appendages of E. clematidis have basal pigmentation (colorless to faintly pigmented), whereas those of E. aquilegiae var. ranunculi are brown throughout or paler towards the apex. Unexpectedly, two types of ascospore morphologies were observed on the specimen of C. glauca (HMJAU -PM 92227): macro-ascospores [14–31 × (6 –) 10–18 µm] and micro-ascospores [4–17 × 4–14 µm] (Fig. 4). Furthermore, some germinating ascospores were also observed, which is very unusual in powdery mildews. More specimens need to be collected to determine whether this phenomenon is common.</p></div>	https://treatment.plazi.org/id/EB51B5414A77514EBDB1F272A0E33027	Public Domain	No known copyright restrictions apply.

Within this genus, two powdery mildew species have been described: Erysiphe aurea and E. limonii (Braun and Cook 2012) . E. aurea is known exclusively from its type collection (HMAS 38952) on L. suffruticosum in Xinjiang, China (Zheng and Yu 1987). Previous identifications of powdery mildew on L. bicolor and L. aureum from Inner Mongolia (CFSZ 1870 and 6794) were attributed to E. limonii (Liu 2010, 2022). Comparative morphological analysis of the examined specimens (with specimens CFSZ 1870 and 6794 borrowed from the Mycological Herbarium of Chifeng College) demonstrated clear differentiation from E. limonii: chasmothecia were significantly smaller (69–112 vs. 90–180 µm), and appendages exhibited fewer septa [0–2 (– 4) vs. 0–7]. Furthermore, the two species exhibit variable ascospore shapes, and are distinct from E. aurea in having septate appendages and lacking the golden-yellow cells of the inner peridial wall.</p><p>Phylogenetic analysis of ITS + 28 S rDNA sequences revealed that the Inner Mongolian isolates formed a well-supported clade with Erysiphe sp. on L. tetragonum from Japan (Meeboon et al. 2021), diverging from E. limonii . Although a single nucleotide difference in the 28 S region was observed, this may reflect geographic or host-associated genetic variation rather than distinct species boundaries. It seems that these two Japanese specimens (= Erysiphe sp.) pertain to the new species, E. limoniicola . Comparative morphometric analysis further revealed incongruences: while Meeboon et al. (2021) reported conidiophore lengths of 50–127 µm on L. tetragonum, our measurements (48–102 µm) partially overlapped with previous records (64–96 µm) (Liu 2010, 2022). Such variability in conidiophore length is a common phenomenon in powdery mildew anamorphs, likely often influenced by external influences.</p></div>	https://treatment.plazi.org/id/F8B6FE8C2ED7508CABD82A6C851ED4D7	Public Domain	No known copyright restrictions apply.

Subsequent reports from China confirmed this identification using ITS data (Qian et al. 2016). While the anamorphic morphologies of E. paeoniae on P. × suffruticosa (designated E. paeoniae-suffruticosae) and P. lactiflora (on E. paeoniae) show no significant differences, their chasmothecium structures exhibit marked morphological divergence. Notably, E. paeoniae-suffruticosae possesses two distinct types of asci and ascospores, whereas E. paeoniae exhibits only a single type. The holotype of E. paeoniae (hosted on P. obovata preserved at the HMAS, Beijing) underwent morphological re-evaluation and molecular analysis; however, all sequencing attempts failed, probably due to the age of the specimen. Despite this limitation, the morphological similarity observed between E. paeoniae populations on P. obovata and P. lactiflora supports the authenticity of E. paeoniae on its type host. Significant morphological differentiation between E. paeoniae-suffruticosae and E. paeoniae is supported by phylogenetic analyses using ITS + 28 S + IGS, which together support recognition of E. paeoniae-suffruticosae as a distinct taxon on P. × suffruticosa (Suppl. material 1). Furthermore, in the multi-gene analysis (ITS + 28 S + IGS + RPB 2 + TUB), E. paeoniae-suffruticosae formed a distinct clade, providing additional evidence for its taxonomic distinction (Fig. 2).</p><p>Field surveys indicate high susceptibility of P. × suffruticosa to powdery mildew, suggesting potential broader geographic distribution of E. paeoniae-suffruticosae within China.</p></div>	https://treatment.plazi.org/id/73D015CE59525B599355793E352C24E3	Public Domain	No known copyright restrictions apply.

However, systematic verification remains critical as many anamorphic records may represent cryptic species or misidentifications within the complex. In 2023, E. punicae was newly documented on pomegranate ( Punica granatum) in India by ITS sequence analysis (Watpade et al. 2023). Our phylogenetically verified collections from Yunnan and Hebei provinces, China, showed morphological congruence with E. punicae (HAL 2441 F) (Bolay et al. 2021) and were supported by phylogenetic analyses (Figs 1, 2). All E. punicae sequences were consistently resolved as a distinct, well-supported clade within the E. aquilegiae complex clade, confirming its taxonomic validity. This is the first reported occurrence of E. punicae in China, extending its known geographic range by both morphological and molecular evidence.</p></div>	https://treatment.plazi.org/id/BBD8D633AF0F5C88833B38ED8043168F	Public Domain	No known copyright restrictions apply.
