First records of Sticta arenosella and S. cellulosa from South America based on molecular and morphological data

Abstract

Two isidiate species, Sticta arenosella and S. cellulosa , are reported from South America for the first time and the former species also as new to Southern Hemisphere. Sticta arenosella was found in Chile and S. celulosa in Bolivia. The identification of both species was confirmed by sequencing of the nuITS rDNA marker, a universal barcode of fungi, and the haplotype network analyses. Specimen of S. celulosa possess sparse apothecia, which previously have not been observed in this species.
