Resumen

GAMUNDI, Irma J. et al. Checklist of the Discomycetes (Fungi) of Patagonia, Tierra del Fuego and adjacent antarctic areas. Darwiniana [online]. 2004, vol.42, n.1-4, pp. 63-164. ISSN 1850-1699.

Information about fungi of the orders Cyttariales, Helotiales, Ostropales, Pezizales, Rhytismatales and Thelebolales (Discomycetes) collected in Patagonia, Tierra del Fuego and adjacent antarctic areas (Patagonia), and information about their associated organisms was located, abstracted, keyboarded, edited and validated. The largest single information sources were dried reference collections in Argentina and elsewhere, and published information as listed in this work's bibliography. Other records were derived from fresh collections, other reference collections and field observations. Information is stored in a computerized system of relational databases for taxonomic, nomenclatural, bibliographic and biological observations data. This system allows storage of parallel data in different languages, and distinguishes original information from current opinion about what that information may mean. In the Biological Records Database, 5029 separate records were created for observations on the spatial and temporal occurrence of living organisms in the region. Of these 2613 were Discomycetes, with records derived as follows: Patagonia and Tierra del Fuego (Argentina, 1854; Chile, 687); adjacent antarctic areas (72). Excluding synonyms, these Discomycetes represented 361 species and subspecific taxa (160 genera, 22 families and 7 orders) the remaining records were organisms associated with these Discomycetes as follows: 163 of animals (8 species, 8 genera, 6 families and 5 orders); 2 of chromistans; 223 of fungi (52 species, 54 genera, 26 families and 13 orders); 2028 of plants (159 species, 122 genera, 59 families and 39 orders). Each of these different taxa (and each known synonym) is represented by a separate record in the Taxonomic & Nomenclatural Database. Information about relevant bibliographic sources is stored in more than 120 records in the Bibliographic Database. The databases were used to produce the present checklist of names given to Discomycetes observed in Patagonia. A typical entry comprises the fungus name, author(s), and information on the original place of publication of the name, together with any known synonyms (classification at generic level and above largely follows the 9th edition of Ainsworth & Bisby's Dictionary of the Fungi, Kirk et al., 2001). This is followed by basic information derived from the databases: the number of times the fungus has been recorded from the region, the date of the earliest record from the region, months in which the fungus has been observed in the region, geographical distribution by country (and within countries by an appropriate subnational division), associated organism and substrata, a list of reference collection numbers identifying preserved specimens and sometimes living isolates of each fungus, and bibliographic citations identifying any published sources of the information. The status of each name is indicated and, where appropriate, synonyms are provided and cross-indexed. The list is accompanied by an explanatory introduction, a taxonomic index, indexes by countries and subnational divisions of the region, by taxonomy of associated organisms and by substrata, and a bibliography. No new taxa are described. Apart from four new nomenclatural combinations, no new scientific names of any sort are knowingly introduced.
