A New Lichen

One of my lichen books calls these blister lichens. The other one calls them star rosette lichens.

Their scientific name is Physcia stellaris.

Black is the most common blister lichen I find here in southern Illinois.

Some blister lichens have brown discs,

and others have green.

The discs are called apothecia and are where the spores are produced.

Then I found a blister lichen with gray discs in the backyard yesterday.

Now I wonder what other colors that I might find?

  3. I think lichens can be just about any color. I’ve even seen blue.
    These are beauties!
