Description: Phytophthora species are best known as pathogens of agricultural crops, or invasive pathogens destroying forests. Little is known about indigenous species, especially in wild ecosystems. Previous work showed that Phytophthora species are relatively abundant in natural streams in forests, but the species present are poorly characterized, and their ecology is essentially unknown. The aim of this work was to compare methods for the collection, identification, and enumeration of Phytophthora spp. in streams. Three methods of isolate collection were compared (leaf baits, pear baits, and filtration), and species identification was carried out using morphological and growth characters, and by DNA sequencing two regions of the genome (ITS rDNA, mitochondrial COX spacer region). Stream sampling was conducted at five locations in the Oak Creek drainage near Corvallis Oregon.
