GAMUNDI, Irma J.  e  AMOS, Victoria. Mycological explorations in Tierra del Fuego. Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.1-2, pp.131-148. ISSN 1851-2372.

A narration of the leading maritime and terrestrial expeditions in Fuegia during the XIX and XX centuries is approached from the point of view of the mycological exploration and published results on the mycobiota, emphazising the Argentine expeditions. Maps with the itinerary of main Argentine expeditions is given. An evaluation of the fungal diversity according to the previous review is presented, comparing the fungal records during both periods that shows duplication of the total number of taxa from 647 species described in XIX century to 1269 in the XX century. Simultaneously there is a decrease from 50.4 % to 19.7 % in the number of new species published. A list of collectors and a table with the state of ex-situ conservation of selected species is presented. A brief comment is given on conservation of habitats supporting fungal population that are disturbed by unsustainable exploitation of natural resources.
