Learning Lichens

 My recent interest has included lichens.

I have two books on lichens — Walk Softly Upon the Earth, published by the Missouri DOC, and Lichens of the North Woods by Joe Walewski.

The Missouri book has the name blister lichen for this common lichen. Walewski’s book calls it a star rosette lichen.

 Both use the scientific name Physcia stellaris.

Spores develop in the disc-shaped fruiting bodies. It commonly grows on deciduous trees.  It’s a foliose lichen, meaning it looks leaflike and has only a few points of attachment to the surface.

 Very few scientific names make it into my permanent memory. Images easily become a visual memory.

That being said, I plan to call this one blister lichen.

  1. Blister lichen is a good name for it. I don’t think I’ve ever seen it. Sometimes it’s hard to find them fruiting, but you got some good shots of it happening.


  2. I don’t think I’ve ever seen this type of lichen in Tennessee, next time I do a river trip I’ll keep my eyes out for it..:-) Great shots too..


  3. I’ve never seen anything like this, but then again, I haven’t been looking. Very interesting post.


    • I’m hooked now that I’m looking. Only thing is photographing the tiny things and identifying them. Since having problems with both, I plan to just enjoy first.
