Phylogenetic data for the description eight new Halophytophthora species and an updated phylogeny for the genus

During an oomycete survey in December 2015 ten previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds and channels in saltmarshes, lagoon ecosystems and river estuaries at seven sites along the Algarve coast in the South of Portugal. Phylogenetic analyses of LSU and ITS datasets, comprising all described Halophytophthora species, the ten new Halophytophthora taxa from Portugal and all relevant and distinctive sequences available from GenBank, provided an updated phylogeny of the genus Halophytophthora s. str. showing for the first time a structure of ten clades designated as Clades 1–10. Nine of the ten new Halophytophthora taxa resided in Clade 6. Based on differences in morphology and temperature-growth relations and a multigene (LSU, ITS, Btub, hsp90, rpl10, tigA, cox1, nadh1, rps10) phylogeny eight new Halophytophthora taxa from Portugal are described here as H. brevisporangia, H. celeris, H. frigida, H. lateralis, H. lusitanica, H. macr...
