Cladonia incrassata. This red fruited species at its stunning best on sandrocks at the Eridge Rocks Reserve in East Sussex. It is much smaller than other red fruited species, and the podetia are often flat, but not always. It can be confused with very small examples of C. diversa which never occurs in quantity as in this photo. It is a nationally scarce species, and away from the sandrocks, can be found on open habitats on peat, and on very rotten wood.
