However, the new strains differ morphologically from C. melanospora in a combination of characters, including the presence of monilioid hyphae, which have not been reported in C. melanospora (Réblová et al. 2024) . Moreover, the new species exhibits relatively high temperature tolerance, with optimal growth observed at 35 ° C, whereas C. melanospora does not grow at this temperature. Ecologically, C. melanospora has been reported as a saprobe on decaying wood, whereas the strains obtained in this study were isolated from rock (Réblová et al. 2024). Pairwise nucleotide comparisons between C. guangdongensis and C. melanospora revealed sequence differences of 23.34 % in the ITS region (116 / 497 bp, excluding gaps), 7.66 % in the LSU region (65 / 849 bp, excluding gaps), and 1.85 % in the SSU region (18 / 973 bp, excluding gaps). Based on morphological characteristics, growth temperature, ecological differences, phylogenetic evidence, and pairwise nucleotide comparisons, we introduce Ceratostomella guangdongensis as a novel species of Ceratostomella .</p></div>	https://treatment.plazi.org/id/25E9199E48525488987588258EC06712	Public Domain	No known copyright restrictions apply.

Sexual morph not observed.</p><p>Habitat and distribution.</p><p>Air; known only from Shenzhen, Guangdong Province, China.</p><p>Notes.</p><p>Pararamichloridium, the type genus of Pararamichloridiaceae, was established by Crous et al. (2017), with P. livistonae designated as the type species, originally isolated from leaves of Livistona australis collected in Australia (Crous et al. 2017). The genus currently comprises five species, namely P. aquisubtropicum, P. caricicola, P. livistonae, P. ouropretoense, and P. verrucosum (Crous et al. 2025) .</p><p>In this study, we introduce Pararamichloridium purpureum as the sixth species of the genus, isolated from laboratory air in Shenzhen, Guangdong Province, China. The species is proposed based on morphological characteristics and multigene phylogenetic analyses inferred from a combined dataset of LSU, ITS, and SSU sequences. Phylogenetically, the new species forms a distinct lineage within Pararamichloridium and is closely related to P. aquisubtropicum, P. caricicola, P. ouropretoense, and P. verrucosum (Fig. 1). However, the new strain forms an independent branch within the genus and is clearly distinguishable from related species based on both morphological and molecular evidence.</p><p>Morphologically, the new species differs from P. aquisubtropicum, which produces relatively long conidiophores (119–202 µm) and larger conidia (4–8 × 3–4.7 μm) (Jayawardena et al. 2023), whereas P. purpureum produces shorter conidiophores (30.4–104.4 × 1.5–3.2 µm) and smaller conidia (3.4–5.6 × 2.2–3.5 µm). The new species can also be distinguished from P. caricicola, which produces relatively slender conidia measuring 6–7 × 3–3.5 µm, whereas P. purpureum forms comparatively ellipsoidal conidia (Crous et al. 2018). In addition, P. verrucosum is characterized by verrucose conidia, a feature not observed in P. purpureum (Crous et al. 2017). Pararamichloridium ouropretoense differs from the new species in having larger conidia (6–8 × 3–4 µm) and more robust conidiophores (50–150 × 4–5 µm) (Crous et al. 2025).</p><p>Pairwise nucleotide comparisons further support the distinctiveness of the new species. The ITS sequence of P. purpureum differs from those of P. aquisubtropicum, P. caricicola, P. ouropretoense, and P. verrucosum by 121 / 519 bp (23.31 %), 131 / 561 bp (23.35 %), 132 / 538 bp (24.54 %), and 139 / 528 bp (26.33 %), respectively (excluding gaps). Similarly, LSU sequence comparisons revealed differences of 100 / 706 bp (14.16 %), 99 / 704 bp (14.06 %), 94 / 703 bp (13.37 %), and 92 / 704 bp (13.07 %) between the new species and these taxa. SSU sequence comparison was only possible with P. verrucosum, as SSU sequence data are not available for the other related species, and the sequences differed 45 / 833 bp (5.40 %). Ecologically, P. purpureum was isolated from air contaminants collected using exposed culture plates, whereas previously described species of Pararamichloridium have mainly been reported from plant-associated substrates or submerged environments. The new strain also consistently produces a diffusible violet-purple pigment on PDA.</p><p>Taken together, phylogenetic placement, morphological differences, nucleotide divergence, and cultural characteristics support the recognition of the strain as a novel species of Pararamichloridium .</p></div>	https://treatment.plazi.org/id/A23AE7A46D0753B996C9552C54F76349	Public Domain	No known copyright restrictions apply.
