Thraustotheca terrestris (Oomycetes), a new species from Argentine agricultural soil
Thraustotheca terrestris sp. nov. occurring in agricultural soil with organic matter (twigs, leaves and roots of wheat, soybean and sunflower) in Buenos Aires province (Argentina) is described, illustrated and compared with other species of the genus. The species produces diclinous and monoclinous antheridial branches, smooth oogonia and eccentric oospores. This Argentine species differs from T. clavata in having both diclinous and monoclinous antheridial branches, the zoosporangia being terminal or intercalary, stout and longer, lacking secondary mycelial branches. The oospores are larger and 1-8(-16) in number.
