Abstract

This study presents new lichen records from two urban green areas in the Lisbon Metropolitan Area, contributing to Portugal's understudied mycobiota. A survey identified 64 species, including three new to Portugal and 21 new to the region. The findings underscore the lichenological richness of anthropized landscapes and highlight the value of citizen science initiatives, such as bioblitzes, in supporting biodiversity documentation.
