TICOLICHEN is a tropical lichen biodiversity inventory that combines local scientific infrastructure with international taxonomic expertise. It forms part of the Costa Rican Sustainable Biodiversity Development Initiative, a collaborative effort to unravel the country's organismic diversity, supported by the World Bank, the Norwegian Agency for International Development, and the Dutch Government.

TICOLICHEN completes the Surveys of Costa Rican Macrofungi (NSF grant DEB 9972027 to Mueller / Halling) and Wood Inhabiting Pyrenomycetes (NSF grant DEB 0072684 to Huhndorf / Fernandez). Thus, efforts are united to compile one of the world's largest inventory of tropical fungi.

TICOLICHEN is derived from the Costa Ricans' nickname 'tico', due to their habit to use this superdiminutive. While most Latin Americans say 'un poco' ('a little bit'), Costa Ricans prefer 'un poquitico' ('a very very little bit'). The creation of the word TICOLICHEN was inspired by Ticodendron, a tree genus described from Costa Rica by Luis Diego Gomez and Jorge Gomez-Laurito. For more information about this enigmatic plant, see Kew's Royal Botanical Garden website and the ATTA database at INBio.

TICOLICHEN is funded by the National Science Foundation, Biotic Surveys & Inventories, Grant DEB-0206125 to The Field Museum (PI Robert Lücking).
