New records of the lichen genus Menegazzia from Africa

A study of African material of the lichen genus Menegazzia was undertaken. Two species are reported as new to the continent; M. capitata from Tanzania, and M. subsimilis from La Réunion, Madagascar, Rwanda and Tanzania. A previous report of M. terebrata from Madagascar is rejected, whereas a previous report of the same species from Tanzania could not be confirmed, but not all Tanzanian specimens cited in the literature were seen.
