Notes.

Morphologically Rugonectria sinica resembles R. castaneicola (W. Yamam. & Oyasu) Hirooka & P. Chaverri in having four-spored asci ( Zeng et al. 2012). However, R. castaneicola differs in possessing perithecia that are 250-470 × 350-430 μm and larger than those of R. sinica that are 216-420 × 194-404 μm. In addition, the ascospores of R. castaneicola are larger, 18-28 × 7.5-11 μm, while those of R. sinica are 16-26 × 5.5-11 μm. The sequence analyses of the ITS and β-tubulin regions from type culture confirmed that they are different taxa ( Zeng et al. 2012).
