Usnea subfloridana

Usnea subfloridana


Fruticose lichen. Bushy, pendulous lichen with colours in the grey-green to yellow-green range, with a distinctive blackened base with annular rings or cracks. The branches are cylindrical and tapered (no flattening). The side branches are not narrowed where they attach to the trunk (they are in some species). The trunk and branches are covered in patches of soredia or isidia. Apothecia are rare and when present there are very few (maybe three on a specimen). Some specimens may consist of just a single stem and a few side branches. This divergent range of types (bushy to simple stems) makes Usnea difficult to identify.
