Microglaena nidarosiensis Kindt has been rediscovered after 100 years on the west-coast of Norway. It is shown to be identical with Clathroporina calcarea W. Watson, and to belong in the genus Belonia which is placed in the Gyalectales as B. nidarosiensis (Kindt) comb. nov.
The genus Clathroporina is typified on C. olivacea Müll. Arg., and is shown not to be present in Europe. C. caudata Vězda & Vivant is transferred to Belonia as B. caudata (Vězda & Vivant) comb. nov.
