Discussion

The confirmed host of Boschniakia rossica is Alnus; unconfirmed hosts include Betula and Vaccinium; dubious hosts include Chamaedaphne, Picea, and Salix.

Boschniakia rossica has a rather uniform morphology in North America; however, var. flavida Y. Zhang & J. Y. Ma has been described in a region of China.
