Notes.

Melanconis betulae was described from Betula albosinensis ( Fan et al. 2016). Morphologically, M. betulae is characterised by ovoid, olive-brown, aseptate alpha conidia, which are different from other Melanconis species but similar to the type species Ms. stilbostoma . However, it can be distinguished by the smaller length of its alpha conidia (10 vs.> 12 μm) and sequence data.
