Two Mosses and a Lichen

I went out this afternoon specifically to photograph a small moss growing in a small fire ring beside my moon garden.

 The Ditrichum pallidum has no common name in my Walk Softly Upon the Earth book, a field guide to Missouri mosses, liverworts and lichens. The stalks stood an inch tall.

A loop walk of part of the backyard turned up another tiny moss, called urn moss (Physcomitrium pryiforme) because of the shape of spore capsules. The stalks on this moss was 1/4 inch tall at the most.

Moss glossary:

 Gametophyte — leafy portion of the plant.

Sporophyte — spore producing part of the plant. It usually has long slender stalk, topped with capsule which produces the spores.

Calyptra — a thin jacket covering the top of the capsule. It later looks like a little hat. (Easier seen in the top picture.)

I noticed a greenish-yellow patch on the bark of the hackberry tree. It was odd that in was only on the southwest side and low on the trunk. Candelaria concolor grows mostly on trees and occasionally on rocks.

  2. Excellent pictures of some hard to photograph subjects. That’s a nice lichen! I’ve noticed that many lichens grow on the side of the tree with the highest humidity-like the side towards, rather than away from a pond, for instance.
