Subsequently, this species has been documented on Pandanus, Citrus trifoliata, and submerged decaying wood (Hyde et al. 2018; Tian et al. 2018; Tibpromma et al. 2018; Tennakoon et al. 2024). In the present study, our specimen was isolated from withered branches of Fagaceae plants in Jiangxi, China. Morphological examination revealed that the ascomata of these strains are consistent with previous descriptions, although subtle variations were observed in ascospore morphology (Hyde et al. 2018; Tian et al. 2018; Tibpromma et al. 2018; Tennakoon et al. 2024) (Suppl. material 1: table S 2). In the phylogenetic analysis, the isolate (EMFCC 0044 and EMFCC 0046) formed a well-supported clade with B. siamensis (MFLUCC 17-1800, MFLU 17-1004, MFLU 18-0032, HFJAU 10336). Therefore, we identified our collection as B. siamensis, and this is a new host record from Fagaceae in China.</p></div>	https://treatment.plazi.org/id/DEEE0D6136BA5F17BF96FFFEFC7BB1A9	Public Domain	No known copyright restrictions apply.

The ascospores of P. biyangense possess more septa (9–18 vs. 7–13 vs. 11–14 vs. 9–13) and wider dimensions compared to P. zhujiangyuanense, P. mali, and P. manglicola (34–47 × 9–12 vs. 35–42 × 9–15 vs. 27–38 × 8–13 vs. 27–36 × 7.5–13). Notably, P. biyangense lacks distinct ostioles (Zhang et al. 2017, 2024; Phukhamsakda 2019; Dayarathne 2020; Jayawardena et al. 2022). In the multi-locus phylogeny, P. biyangense showed close affinity to P. manglicola (NFCCI 4666). The ITS, LSU, SSU, and tef 1 - α base pair differences between two species (excluding gaps) are 3 / 413 bp (0.61 %), 3 / 790 bp (0.38 %), 198 / 1034 bp (11.91 %), and 3 / 757 bp (0.40 %), respectively. Thus, we describe P. biyangense as a novel species.</p></div>	https://treatment.plazi.org/id/620C5D2BBEFE52B2AB13A80596AEE091	Public Domain	No known copyright restrictions apply.

In the phylogenetic analyses, our isolates of P. fagacearum (EMFCC 0043 and EMFCC 0047) formed a well-separated lineage distinct in Pseudothyridariella with high statistical support (83 % ML / 0.99 BPP).</p><p>The genus Pseudothyridariella currently comprises two asexual species, P. aquilariae and P. idesiae (Li et al. 2023; Tian et al. 2024), and two sexual morph species, P. chromolaenae and P. mahakoshae (Devadatha et al. 2018; Mapook et al. 2020). Pseudothyridariella fagacearum can be distinguished from P. chromolaenae and P. mahakoshae by larger asci (70–220 × 10–20 µm vs. 88–138 × 24–36 µm vs. 80–135 × 14–22 µm) and larger ascospores (47–66 × 13–23 µm vs. 23–28 × 9–12.5 µm vs. 17–27 × 5–12 µm). Additionally, the ascospores of P. fagacearum are hyaline, 8 - septate, and lacking a longitudinal septum. In contrast, the ascospores of P. chromolaenae are brown, olivaceous brown to dark brown at maturity, with 5–8 transverse septa and 1 longitudinal septum (Mapook et al. 2020), while those of P. mahakoshae are hyaline, with 3–6 transverse septa and 1 longitudinal septum (Devadatha et al. 2018). Therefore, based on both phylogenetic and morphological evidence, P. fagacearum was described herein as a new species.</p></div>	https://treatment.plazi.org/id/97577987EBBF59B78081BBD578B017EC	Public Domain	No known copyright restrictions apply.
