At present, the searchable database houses about 10,000 records of macrofungi and 20,000 records of lichens (including duplicates), distributed among F, INB, CR, USJ, NY, WIS, B, and other institutions. Data on microfungi are expected to be added soon. You can search the database for particular taxa and get data on their distribution and ecology, or you can search specific regions or sites within Costa Rica to get a list of the taxa present in the area.
Note that part of the identifications are to genus level only; species identifications will be completed as soon as groups have been revised. Most collections are from protected areas, and site names have been standardized to reflect official names in international (English) spelling. In most cases, you can either search for a site (e.g., Corvocado National Park), a subsite (e.g., Sirena Biological Station), or a higher level conservation area (e.g., Osa Conservation Area), in the site name field.
