Armillaria nabsnona, a New Species from Western North America

Abstract

Armillaria nabsnona is characterized morphologically and described as a new species. It is compatible with tester strains of North American biological species (NABS) IX. Using restriction fragment length polymorphism (RFLP) of the polymerase chain reaction (PCR) products amplified from the intergenic spacer (IGS) region of the ribosomal DNA, we also demonstrate an association of cultures of specimens with tester strains of NABS IX. Armillaria nabsnona appears to be restricted to several species of hardwood trees in the states of Washington, Oregon, California, Idaho and Alaska, and in the Canadian province of British Columbia. Basidiomata have been found in both the fall and spring.
