Two disjunct moss species new to Mexico

Meteorium flexicaule Wils. in Hook. and Aligrimmia peruviana R.S. Williams are newly recorded for the Mexican moss flora. The former is briefly described and illustrated from a collection in San Luis Potosí (Ahuacatlán); the latter was collected in Nevado de Toluca, state of Mexico. Previous continental reports for both species are South American.
