Notes.
Melanconis itoana
was described from
Betula ermanii
in Japan (
Kobayashi 1970
).
Fan et al. (2016)
isolated it from
Betula albosinensis
as a new record in China.
Melanconis itoana
is characterised by fusoid, green-brown alpha conidia with acute ends (13
x
4
μm
) and hyaline, cylindrical or crescent beta conidia (9.5
x
1.5
μm
).
