Miniscule Comes to Mind

  I walk loops around our backyard for the exercise, and so I can watch for any photographic opportunity.

Lichens are common on both live and dead wood.

The Whitewash lichen (Phlyctis argena) above is similar to Common Button lichen (Buellia stillingiana), which has more black dots. The spores are produced in the dots, called the apothecia.

I rotated this and the next picture, because it makes it easier to see the lichens.

Candleflame lichen (Candelaria concolor) is the yellowgreen one on the bark of a hackberry tree. Research online shows that its color can vary.

My Lichens of the North Woods book gives 0.1-0.5 mm for the width of the its lobes!


A Small Snow Cave

A small snow cave partially covers ed blister lichen (Physcia stellaris)  growing on a limb in our dawn redwood tree. It’s also called a star rosette lichen. It’s a foliose lichen — a leafy looking lichen (say that three times fast). They reproduce by spores, which is the black in each disc.

Another New Lichen

This lichen grew on a dead tree, near a trail, along a lake.

I was able to identify it with my Lichens of the North Woods book.

It’s a Smooth Axil-bristle Lichen (Myelochroa galbina).

The size of the fruiting bodies varied considerably. It looks as if the cups opened, and a thin “sheet” of spores flaked off.

It was quite a variable lichen.

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?

Bird’s Nest Fungi

There’s advantages to weeding in the garden ….

IMG_1501 crop

like finding these bird’s nest fungi.


I’ve found them many times over the years …. I’ve just never found them growing in an old rotting gumball.


This unopened cup measured roughly a quarter-inch in diameter.

A strip of rotting wood laid near a wall and had the birds’ nest fungi too.

The eggs contain the spores.
