with four incrementally heated chains, which were run for 6 million generations, with every 1 000th tree sampled. The first33 % of these trees were discarded and the remaining trees
were used for computing a majority rule consensus tree and for inferring posterior probabilities. For the comparison of sequence divergence of partial nrLSU of LT6440 to selected members of other oomycete families, theblastn algorithm was used, with standard parameters except for settings in match/mismatch scores (4, -5) and gape costs (existence: 5, extension: 5). These parameters were altered for maximizing the query coverage to 100 % in the queries. The sequence divergence of LT6440 to the type species of selected genera are listed in Table 3.
