Identification:

Powder-tipped rosettes are a type of common lichen. Lichens are complex organisms that arise from symbiotic relationships between fungi and a photosynthesizer, like algae. The genus name, Physcia, means “inflated” or “sausage-like,” which is used to describe the physical form the various species within the genus take. The powder-tipped rosette generally appears in shades of gray, with a whitish-gray upper and a distinctly darker gray on the ends of the lobes.

Fast Facts:

  • The powder-tipped rosette is commonly misidentified for a couple other lichens that all appear very similar, initially. The hooded rosette lichen, hooded tube lichen, and star rosette lichen share several features in terms of color and branching!
