Pairwise base pair comparisons in the currently available LSU and SSU gene regions revealed 12 (0.92 %, excluding gaps) and one (0.13 %, excluding gaps) nucleotide differences between A. bambusae and A. subprolata (MFLUCC 18-1314), respectively. Comparisons using the combined multi-gene matrix (ITS – LSU – SSU – RPB 2 – TEF 1 - α) showed that A. bambusae exhibits 130 nucleotide differences (2.79 %, including two gaps) relative to A. lignicola . Morphologically, A. bambusae is most similar to A. ovalia, A. stellata, and A. subprolata in having acrogenous or acropleurogenous, solitary, mostly oval to broadly ellipsoidal, and thick-walled conidia. However, our new collection differs from A. ovalia and A. stellata by its conidial size (33–52 × 24–41 µm vs. 24–33 × 18–22 and 25–30 × 15–20 μm), respectively (Goh et al. 1998; Tan et al. 2022), and differs from A. subprolata by its longer (254–533 µm vs. 150–300 µm) conidiophores (Goh et al. 1998). Additionally, A. bambusae differs from A. lignicola in having different conidial shapes (mostly oval to broadly ellipsoidal vs. mostly broadly obovoid) and colors (hyaline when young, orange-brown at maturity vs. dark brown to black). More importantly, A. bambusae is distinct from A. lignicola, A. ovalia, A. stellata, and A. subprolata in our phylogenetic tree. Therefore, A. bambusae is introduced as a new taxon within Acrogenospora based on morphology and phylogeny. A comprehensive morphological comparison with related Acrogenospora species is provided in Table 2.</p></div>	https://treatment.plazi.org/id/615EBDCEC8215495A313F24E7949F93D	Public Domain	No known copyright restrictions apply.

However, as mentioned above, A. lignicola can be easily distinguished from A. bambusae by its conidial shape and conidial color (Table 2). Morphologically, Acrogenospora lignicola is most similar to A. basalicellularispora and A. obovoidispora in having oval to broadly obovoid conidia (Bao et al. 2020). However, A. lignicola can be distinguished from them by its thinner conidiophores (4.5–7.5 µm vs. 8–12 µm and 7.5–10 µm). Furthermore, A. lignicola differs from A. basalicellularispora by its dark brown to black conidia that lack a basal cell, whereas A. basalicellularispora has pale orange-brown to olivaceous brown conidia with a small, hyaline, subcylindrical to subglobose basal cell (Bao et al. 2020). According to phylogenetic and morphological evidence, we introduce A. lignicola as a new species in Acrogenospora .</p></div>	https://treatment.plazi.org/id/8553AC8FCC9D5F1B91241927E970ED13	Public Domain	No known copyright restrictions apply.

At the ITS locus, the newly isolated strains JAUCC 5524 and JAUCC 5528 showed four and six nucleotide differences (excluding gaps), respectively, compared to the holotype of A. taiwanica TNM 5903, while exhibiting only two and four (excluding gaps) differences relative to A. taiwanica BCRC FU 3153 (Kirschner 2025). Furthermore, our two strains showed no variation in their LSU sequences and were identical to A. taiwanica BCRC FU 3153. Morphologically, our new collections resemble the holotype of A. taiwanica, except for the slightly larger (21–32.5 μm vs. 21.5–25 μm) conidia (Kirschner 2025). The difference in conidial size might be due to factors such as habitat and incubation time (Yang et al. 2018; Zhang et al. 2022).
