To date, 434 taxa have been recorded for both countries, being 174 (14 Blastocladiomycota, 42 Chytridiomycota, two Hyphochytriomycota, three Labyrinthulomycota, 112 Oomycota and one Phytomyxea) for Argentina and 348 (18 Blastocladiomycota, 121 Chytridiomycota, five Hyphochytriomycota, four Labyrinthulomycota, 196 Oomycota and four Phytomyxea) for Brazil.
The first record of Chytridiomycota in this country was of Synchytrium stellariae Fuckel parasiting the plant Stellaria media W.
Considering that the estimated percentage of known species of Chytridiomycota and Oomycota is quite small (Mueller & Schmit, 2007), human activities and environmental change may lead to species losses before they have even been discovered.
