Comparatively, the LSU gene region displayed 99.43 % similarity to S. lichenicola (CBS 160.25) with 99 % query cover, translating to 98.44 % similarity, while the closest match of the tub 2 sequence with 94.57 % similarity was S. rotundatus (CBS 616.83). Sporocadus changchunensis (EMFCC 0014) formed a sister clade to S. rotundatus (CBS 616.83) with strong bootstrap support (93 % ML and 0.99 BPP). The base pair differences between the two species are 3 bp in ITS, 29 bp in tef 1 - α, 20 bp in rpb 2, and 35 bp in tub 2. The new isolates also share a close phylogenetic affinity to S. cavernicola . However, there is no report for the sexual morph of S. cavernicola and S. rotundatus (Liu et al. 2019; Razaghi et al. 2024). Morphologically, Sporocadus changchunensis differs from S. italicus, which was also found on Crataegus, by its narrower ostiolar canal (75 × 50 vs. 80 × 75 µm), wider hamathecium (4–7 vs. 2.6–4.1 μm), and smaller asci (71–88 × 7–8 vs. 102–129 × 8.5–10 μm) (Hyde et al. 2017). Additionally, the ascospores of S. italicus are ellipsoidal-fusiform or ampulliform, multi-seriate, and sometimes contain one vertical septum, whereas those of S. changchunensis are fusiform to oval, uniseriate, and without a vertical septum (Hyde et al. 2017). Hence, we introduce S. changchunensis as a novel species, and this is the first report of Sporocadus species in Northeast China.</p></div>	https://treatment.plazi.org/id/161496BC9A665CDD83234B7F4C447EB1	Public Domain	No known copyright restrictions apply.

The LSU sequence showed 99.54 % similarity to S. lichenicola (CBS 160.25) across 98 % of the query sequence, which translates to 97.55 % similarity. The closest rpb 2 and tef 1 - α matches were S. rotundatus (CBS 616.83) with 95.99 % similarity and 95.24 % similarity, respectively. The morphology of the conidiomata, conidia, and median cells of our isolate fits well with the descriptions of the asexual morph of Sporocadus (Nag Raj 1993; Liu et al. 2019). Phylogenetic analyses of combined ITS, LSU, rpb 2, tef 1 - α, and tub 2 datasets (Fig. 1) show that S. crataegicola (EMFCC 0015) formed a distinct clade and clustered with S. changchunensis and S. rotundatus with 98 % ML and 1.00 BPP. Conidia of S. rotundatus are clavate, obovoid, ellipsoid, or cylindrical (with rounded ends) and have 1–4 septa, whereas those of our isolate are fusiform with 0–3 septa. The asexual morph of S. changchunensis remains undetermined. Notably, Sporocadus crataegicola differs from S. changchunensis in 7 / 560 bp in ITS, 10 / 875 bp in LSU, 28 / 819 bp in rpb 2, and 27 / 452 bp in tef 1 - α. Thus, we describe our isolate as a new taxon herein.</p></div>	https://treatment.plazi.org/id/B16531C9BD155E50AD48AE9FBD4E0E83	Public Domain	No known copyright restrictions apply.
