Thelonectria yunnanica Z.Q. Zeng & W.Y. Zhuang, Phytotaxa 85(1): 19, 2013

Specimen examined.

CHINA. Yunnan, Baoshan, on bark of an unidentified tree, 15 October 2003, W.P. Wu W7122 (HMAS 183564), ex-type culture: HMAS 188567.

Sequences.

ACT (MF669049), ITS (FJ560438), LSU (MF669055) and RPB1 (MF669061).

Habitat.

On bark.

Distribution.

Asia (China).

Notes.

Thelonectria yunnanica is only known from the type locality. It is phylogenetically related to T. ostrina ( Figure 1 ). However, T. ostrina has a perithecial wall 25-40 μm while those of T. yunnanica are thicker 49-71 μm and have asci that are (56 –)67– 86(−98) × 7-12 μm while those of T. yunnanica are larger, 87-120 × 8.2-9.6 μm. Unlike T. yunnanica , T. ostrina does not forming microconidia in culture ( Zeng and Zhuang 2013; Salgado-Salazar et al. 2015).
