Importance and distribution

Rhytidiella comprises four species known on Populus sp. (Salicaceae) and on exposed roots of Hebe elliptica (Plantaginaceae). Rhytidiella may be specific to host plant and families. Rhytidiella is geographically distributed in New Zealand (Antipodean Islands), North America (Canada (British Columbia)) and the United States (Alaska, California). Rhytidiella causes rough-bark disease of Populus balsamifera (Zalasky 1968).
