A new species of Cresponea (Roccellaceae, Ascomycota) from Gough Island

Scientists have identified a new species of lichen, Cresponea sorediata, from Gough Island, part of the UNESCO-listed Gough and Inaccessible Islands. This discovery is notable for its unique characteristics: a sorediate thallus (without apothecia) and diagnostic substances including usnic acid and is. The research relied on morphological analysis and chemical profiling to distinguish this species from others in the Cresponea genus, contributing to our understanding of biodiversity in remote oceanic environments.
