New additions to the lichen genus Enterographa (Roccellaceae) from Everglades National Park including an updated world key
Published online by Cambridge University Press: 09 January 2014
During 2010–12 collecting seasons, we visited 27 islands, locally called keys, in Florida Bay within the boundaries of Everglades National Park for the purpose of investigating their lichen flora. A disproportionate number of the resultant collections belong to Enterographa Fée, a genus mostly tropical in distribution. Currently, 11 species are known from Everglades National Park, of which Enterographa bradleyana, E. caudata, E. murrayana and E. nitidula are described here as new to science. Enterographa bradleyana is superificially similar to Enterographa divergens but has smaller ascospores, a wider perispore and contains gyrophoric acid. Enterographa candata is easily identified by an unusual chemistry of lichexanthone and schizopeltic acid and its extremely long tailed ascospores. Enterographa murrayana resembles E. anguinella in the field but has a different chemistry, wider ascospores with more septation and a wider perispore. Enterographa nitidula has an unusual fine powdery and glossy thallus, small 4-celled ascospores and contains an unidentified substance. Because a large number of Enterographa have been described (20 including those newly described here) since Sparrius monographed the genus in 2004, an updated world key to the genus is provided.
