Abstract
Although Armillaria has been previously surveyed in several western states of the USA, little definitive information on Armillaria species distribution in California has been provided in the last 20 years (e.g., Baumgartner and Rizzo 2001). Furthermore, it is well established that climate and climate change influence the distribution of Armillaria species that cause Armillaria root disease, which is a major cause of losses in forest growth and productivity (e.g., Lockman and Kearns 2016; Kim et al. 2021, 2022). This paper details recent progress towards identifying Armillaria for subsequent use in bioclimatic modeling to predict the influences of climate and climate change on the distribution of Armillaria species in California.
