A survey of the fungi associated with salal (Gaultheria shallon Pursh), a serious competitor with conifers in forest regeneration sites, was conducted during the summer of 1999 on southern Vancouver Island. Diseased salal leaves and stems were collected from 25 different sites, and fungi were cultured from surface sterilized tissue on different media, within 24 h of collecting. To date, 391 per fungal cultures have been isolated, and 202 of them have been identified by examining sexual and asexual reproductive structures using compound microscopy. Thirty-nine taxa of fungi have been identified, of which 27 fungi are new records, and 12 have been previously reported on salal. The most common fungi isolated from severe leaf spots on salal under field conditions were Alternaria sp., Monochaetia sp., Pestalotiopsis spp., Phoma sp., Phomopsis sp., Phyllosticta pyrolae, and Valdensinia heterodoxa. Ongoing research is focused on screening, selection, formulation and application of the potential fungal pathogens as biocontrol agents for salal.
