Mushrooms are plentiful at Santa Rita, a 1,700 acre ranch in the heart of the coastal Adelaida Mountain Range in Central California. We hypothesize that fungal diversity at Santa Rita Ranch is high and includes species of potential conservation interest. Using FUNDIS framework, this project will host volunteers to contribute to open-source FUNDIS iNaturalist database. This supports the CA FUNDIS mission to establish a fungal biodiversity baseline for California conservation goals.
