Conidiophores indistinct and always reduced to conidiogenous cells. Conidiogenous cells polyblastic, hyaline, straight or slightly curved, smooth-walled, arising from apices of branched hyphae, 1.4–3.7 × 1.2–2.0 μm (x ̄ = 2.4 × 1.6 μm, n = 15). Conidia solitary, smooth-walled, elliptical or fusiform, septate, 2–3 - septate, and straight or slightly curved, 5.4–11.6 × 1.5–2.7 μm (x ̄ = 7.1 × 2.1 μm, n = 65). Chlamydospores not observed.

After 14 days of cultivation, the colonies attained a diameter of 65–87 mm, with a daily growth rate ranging from 4.6 to 6.2 mm. Colonies exhibited an irregular outward growth pattern, covered with abundant white aerial mycelium. With prolonged incubation, the central region of the colony gradually changed from white to yellowish-brown, and the pigmentation subsequently extended toward the peripheral areas. The reverse surface was white at the initial stage and ultimately turned orange. Sparse sporulation was observed on PDA after 14 days of incubation.</p><p>Notes.</p><p>Based on phylogenetic analysis combined with four sequences (ITS, LSU, RPB 2, and TUB 2), Microdochium acronychicola (SAUCC 620701 and SAUCC 620702) constitutes an independent clade in the phylogenetic trees, closely related to M. hainanense (SAUCC 210781 and SAUCC 210782) and M. bambusinum (SAUCC 7638-2 and SAUCC 7531-3). Microdochium acronychicola (SAUCC 620701, ex-type) is distinguished from M. hainanense (SAUCC 210781, ex-type) by 18 / 558, 1 / 805, 62 / 976, and 35 / 753 characters in ITS, LSU, RPB 2, and TUB 2 sequences, respectively, with all gap sites excluded from the sequence comparisons. Microdochium acronychicola (SAUCC 620701, ex-type) is distinguished from M. bambusinum (SAUCC 7638-2, ex-type) by 18 / 548, 11 / 806, 89 / 897, and 93 / 767 characters in ITS, LSU, RPB 2, and TUB 2 sequences, respectively, with all gap sites excluded from the sequence comparisons. Morphologically, the conidia of M. acronychicola (HMAS 354067, holotype) are shorter than those of M. hainanense (HMAS 352156, holotype) S. B. Liu, X. Y. Liu, Z. Meng &amp; X. G.

It was also found that the collection of M. acronychicola (SAUCC 620701 and SAUCC 620702) is closely related to two other species in this collection, namely M. chinense (SAUCC 1516001 and SAUCC 1516002) and M. brevisporum (SAUCC 785206 and SAUCC 785207). Microdochium acronychicola (SAUCC 620701, ex-type) is distinguished from M. chinense (SAUCC 1516001, ex-type) by 4 / 550, 3 / 810, 16 / 974, and 25 / 750 characters in ITS, LSU, RPB 2, and TUB 2 sequences, respectively, with all gap sites excluded from the sequence comparisons. Microdochium acronychicola (SAUCC 620701, ex-type) is distinguished from M. brevisporum (SAUCC 785206, ex-type) by 19 / 554, 16 / 788, and 50 / 733 characters in ITS, LSU, and TUB 2 sequences, respectively, with all gap sites excluded from the sequence comparisons. Morphologically, the conidiogenous cells of M. acronychicola (HMAS 354067, holotype) are shorter than those of M. chinense (HMAS 354069, holotype) and M. brevisporum (HMAS 354068, holotype) (1.4–3.7 × 1.2–2.0 μm vs. 4.2–22.9 × 1.7–2.3 μm vs. 1.4–9.6 × 0.9–3.0 μm).
