Character Abstract
Identification Comments:
Subspecies Comments:
Phenology Comments:
Reproduction Comments:Reproduction is apparently entirely asexual by wind-dispersal of the thallus or thallus fragments "tumbleweed"-style.
Habitat Comments:Areas of high soil pH, often in Artemisia nova and Sphaeromeria argentea habitats. Also in calcareous badlands of volcanic ash deposits. Vagrant lichens often do best in slight depressions where liquid water collects and may keep the lichens hydrated for long periods. Vagrant lichens are usually found among shrubs less than 0.5 m tall, possibly due to inhibition of wind dispersal by larger shrubs. One author has noted very low annual precipitation, but cold, windy, foggy, and overcast winters.
Ecology Comments:
Inventory Comments:Not yet systematically surveyed in Nevada.
