Fakahatchee Strand Preserve State Park is located in Collier County at the extreme southwestern corner of Florida, close to Everglades National Park and Big Cypress National Preserve. The 18th Tuckerman Workshop, an annual gathering of professional and amateur lichenologists and mycologists from the United States and Canada, this time with additional participants from Puerto Rico, Peru, and Austria, was held at this locality from March 1–7, 2009. Lichens were collected over a five day span from four sites within the Preserve. Together with previously made collections, the survey produced a total of 432 taxa, 18 of which are new to science and 89 are additions to the North America checklist, six of which are also new to the New World. The new species are: Calopadia floridana Hodges & Lücking, Calopadia imshaugii Common & Lücking, Cryptothecia miniata Vain. ex Lücking, Diorygma microsporum M. Cáceres & Lücking (formally described in a separate paper), Fissurina aggregatula Common & Lücking, Fissurina analphabetica Common & Lücking, Fissurina confusa Common & Lücking, Fissurina inspersa Common & Lücking, Fissurina pseudostromatica Lücking & Rivas Plata, Fissurina subcomparimuralis Common & Lücking (formally described in a separate paper), Fissurina tuckermaniana Common & Lücking, Fissurina varieseptata Common & Lücking, Graphis appendiculata Common & Lücking, Halegrapha floridana Common & Lücking (formally described in a separate paper), Heiomasia seaveyorum M. P. Nelsen & Lücking (formally described in a separate paper), Phaeographis delicatula Common & Lücking, Tapellaria floridensis Common & Lücking, and Tapellaria granulosa Lücking & Rivas Plata. Further, the following three new combinations are proposed: Chapsa platycarpoides (Tuck.) Breuss & Lücking, Fissurina intercludens (Nyl.) Lücking & Rivas Plata, and Fissurina mexicana (Zahlbr.) Lücking & Rivas Plata. Six species are for the first time reported for the New World: Arthonia interveniens Nyl., Arthonia simplicascens Nyl., Chapsa subpatens (Hale) Mangold, Fissurina crassilabra Mont. & Bosch, Stirtonia dubia A. L. Sm., and Stirtonia macrocarpa Makhija & Patw. Further 83 species are additions to the North American lichen checklist: Amandinea endachroa (Malme) Marbach, Anisomeridium subnexum (Nyl.) R. C. Harris, Arthonia antillarum (Fée) Nyl., Aspidothelium cinerascens Vain., Aspidothelium geminiparum (Malme) R. Sant., Aspidothelium scutellicarpum Lücking, Astrothelium diplocarpoides Müll.

The high number of species found within a relatively small area, which corresponds to almost 10% of all lichens currently known in North America, is put into perspective by comparing it with other protected areas in the United States. It is explained by the high carrying capacity of (sub-)tropical vegetation for epiphytic and particularly crustose lichens. Keytables and image plates are presented to facilitate the identification of species in larger crustose genera.
