Maximum likelihood tree reconstruction of S. velencensis sp. n. based on a 730-bp ITS–rDNA alignment.
The numbers at the nodes represent the bootstrap support in percentage (>50). The analyses included Saprolegnia spp. sequences obtained from the NCBI GenBank. S. australis and S. ferax sequences labelled in bold represent samples we isolated previously, but sequenced in the present study. Achlya caroliniana was used as an outgroup.
