Resumen

MARANO, Agostina V.; STECIOW, Mónica M.  y  GONZALEZ, Beatriz A.. First record for Argentina of Rhizophlyctis rosea (Spizellomycetales, Chytridiomycota) and notes on its frequency and abundance in cultivated soils. Bol. Soc. Argent. Bot. [online]. 2006, vol.41, n.3-4, pp.183-191. ISSN 1851-2372.

Soil samples from two strawberry fields in Partido de Luján (Provincia de Buenos Aires) were collected, flooded and baited with cellulose, queratinic and chitinic substrates in order to obtain R. rosea (de Bary & Woronin) A. Fisch. All kinds of materials employed, proved positive for this species. By standardizing the substrata addition, we analyzed frequency and abundance and by counting the thalli that grew on it, derivations of thallus density and thallus recovery per gram of soil (TRG) were possible. Water and sediment samples from aquatic environments were also taken, with the aim of reporting morphological characters from different strains, and make a complete description of R. rosea. This species is recorded for the first time in Argentina and this contribution shows first quantitative results of soil fungi belonging to the Phylum Chytridiomycota , for our country. The genus Rhizophlyctis A. Fischer is also a new record for the country.

Palabras clave : Abundance; Chytridiomycota; Frequency; Rhizophlyctis; Soil.
