The species is most closely related to T. christiani (CBS 132572), T. concentricum (HMAS 248833), T. ingratum (HMAS 248822), and T. perviride (HMAS 273786). Because no ITS sequences were available for these comparisons, genetic distances were assessed using only tef 1 - α and rpb 2. Trichoderma diqingense differs from T. christiani by 1.4 % (10 / 733 bp) in tef 1 - α and 2.5 % (27 / 1,072 bp) in rpb 2; from T. concentricum by 0.3 % (2 / 762 bp) in tef 1 - α and 2.7 % (29 / 1,064 bp) in rpb 2; from T. ingratum by 0.4 % (3 / 762 bp) in tef 1 - α and 1.9 % (20 / 1,064 bp) in rpb 2; and from T. perviride by 0.4 % (3 / 733 bp) in tef 1 - α and 2.5 % (27 / 1,072 bp) in rpb 2. Morphologically, T. diqingense is distinguished by its slender lageniform phialides (6.2–12.4 × 2.2–3.2 μm) compared with those of T. christiani (6.0–11.0 × 2.7–3.5 μm), T. concentricum (8.6–11.7 × 2.5–3.6 μm), and T. ingratum (8.3–12.4 × 2.8–3.5 μm) and by its longer phialides compared with those of T. perviride (5.0–8.0 × 1.7–2.3 μm). Its conidia are relatively small and narrowly ellipsoidal (2.4–3.5 × 1.5–2.9 μm), in contrast to the larger, globose to subglobose conidia of T. christiani (2.5–3.7 × 2.7–3.0 μm), T. concentricum (2.6–3.3 × 2.6–3.3 μm), T. ingratum (2.6–3.6 × 2.6–3.2 μm), and T. perviride (2.8–3.5 × 2.7–3.3 μm). In addition, chlamydospores are absent in T. diqingense but present in T. christiani (6.0–9.0 × 5–8 μm) and T. perviride (5–6 × 5–5.5 μm). The species also lacks the characteristic coconut-like odor reported for T. concentricum and T. ingratum (Jaklitsch and Voglmayr 2015; Chen and Zhuang 2017; Qin and Zhuang 2017). Based on the multilocus phylogenetic and detailed morphological evidence, T. diqingense is introduced here as a new species.</p></div>	https://treatment.plazi.org/id/57D656F3AD7C51A4BE09C80C5846DF5E	Public Domain	No known copyright restrictions apply.

Because no ITS sequences were available for comparison, genetic distances were assessed using only tef 1 - α and rpb 2. Trichoderma dracaenae can be distinguished from T. speciosum by 1.8 % (17 / 925 bp, including 1 gap) in tef 1 - α and 2.3 % (20 / 868 bp) in rpb 2 and from T. sphaerosporum by 0.79 % (8 / 1,018 bp, including 1 gap) in tef 1 - α and 2.4 % (17 / 906 bp) in rpb 2. Morphologically, T. dracaenae has conidiophores with a distinct cylindrical main axis and usually 2–3 branches, differing from the tree-type conidiophores with paired or whorled branches in T. speciosum, and the typical Trichoderma - type conidiophores of T. sphaerosporum, which sporulates rapidly on CMD and PDA within 2–3 days. Phialides of T. dracaenae are ampulliform, usually curved toward the apex, and broader (5.3–11.6 × 2.1–3.6 μm) than those of T. speciosum (5.0–10.0 × 2.0–3.0 μm) and T. sphaerosporum (6.5–10 × 2–2.5 μm).

In addition, T. dracaenae lacks the distinct coconut-like odor reported for T. sphaerosporum (Qin and Zhuang 2016; Qiao et al. 2018).

Trichoderma fertile was first described from soil under wheat in Canada (Bissett 1991 b). Morphological observations and measurements are based on the single culture KUNCC 11581. The strain is morphologically consistent with the protologue of T. fertile in conidiophore structure, yellow-green pustulate conidiation, ampulliform phialides, and smooth-walled green conidia. However, it differs from the protologue in having slightly smaller conidia (2.4–3.4 × 1.7–2.6 μm vs. 3.0–4.5 × 1.9–2.5 μm) and in the absence of chlamydospores, which were reported as rare in the protologue (Bissett 1991 b).

Strain KUNCC 11579 shares nearly identical sequences with both T. inconspicuum and T. paraviridescens . It differs from T. inconspicuum by 0.60 % (6 / 979 bp) in tef 1 - α and 0.57 % (6 / 1,048 bp) in rpb 2, and from T. paraviridescens by 0.60 % (6 / 1,002 bp, including 3 gaps) in tef 1 - α and 0.55 % (6 / 1,093 bp) in rpb 2. ITS differs from T. inconspicuum by 0.17 % (1 / 597 bp) and from T. paraviridescens by 0.35 % (2 / 572 bp, including 2 gaps). However, ITS alone offers limited resolution for species-level discrimination in Trichoderma, especially among closely related taxa (Cai and Druzhinina 2021). Morphologically, strain KUNCC 11579 differs from T. inconspicuum in having longer phialides (23.7–37.1 × 5.0–7.2 μm vs. 6.4–14.4 × 1.9–4.0 μm) and larger conidia (5.7–8.3 × 3.9–6.6 μm vs. 2.8–4.5 × 2.6–4.0 μm) (Zheng et al. 2021). In contrast, strain KUNCC 11579 is broadly consistent with the protologue of T. paraviridescens in conidiophores, phialides, chlamydospores, and conidia. Trichoderma paraviridescens was originally described from the decorticated wood of Fagus sylvatica in Austria and is known from wood-, bark-, and fungus-associated substrates (Jaklitsch et al. 2013). Therefore, although strain KUNCC 11579 is phylogenetically close to T. inconspicuum, its morphological divergence from that species, together with its general agreement with T. paraviridescens, supports its identification as the latter and represents a new substrate record from the stroma of O. sinensis in China.</p></div>	https://treatment.plazi.org/id/F927F495574B59669EB842D00FD09C0A	Public Domain	No known copyright restrictions apply.

The species is most closely related to T. parapiluliferum (GJS 91-60) and T. shangrilaense (WT 34004). However, T. yuxiense differs from T. parapiluliferum by 2.2 % (17 / 329 bp, including 4 gaps) in tef 1 - α and 2.8 % (30 / 1,087 bp, including 1 gap) in rpb 2 and from T. shangrilaense by 2.5 % (25 / 1,004 bp, including 2 gaps) in tef 1 - α and 2.7 % (29 / 1,099 bp, including 2 gaps) in rpb 2. The ITS sequences are identical to those of T. parapiluliferum (0 / 580 bp) and T. shangrilaense (0 / 574 bp). Morphologically, T. yuxiense differs from T. parapiluliferum and T. shangrilaense in three main features. Its phialides are longer and narrower (8.0–11.1 × 1.9–2.9 μm) than those of T. parapiluliferum (4.5–7.5 × 2.4–3.5 μm) and T. shangrilaense (5.7–9.0 × 3.2–3.5 μm), the latter being flask-shaped and often curved. Its conidia are subglobose to broadly ellipsoidal (2.4–3.5 × 1.5–2.5 μm), whereas T. parapiluliferum has ellipsoidal to oblong conidia and T. shangrilaense has obovoid to ellipsoidal conidia (3.5–4.0 × 3.0–3.3 μm). Chlamydospores are rare and mostly terminal in T. yuxiense (3.6–7.2 × 2.4–5.3 μm), similar to those of T. parapiluliferum (6.0–8.5 × 5.5–8.0 μm), but absent in T. shangrilaense (Lu et al. 2004; Jaklitsch and Voglmayr 2013; Zhang et al. 2022). Therefore, based on the concordant evidence from phylogeny and morphology, T. yuxiense is proposed here as a new species.</p></div>	https://treatment.plazi.org/id/32C66AFEE9C650769479731311CE8C8B	Public Domain	No known copyright restrictions apply.
