A very
abundant, coarsely lumpy white lichen dominating the soil in
late-melting alpine snow-bed areas. This is a lichen that has never
been known to fruit (what we call lichenes imperfecti). Several
other species occur in forests, often at the bases of trees and
sometimes on rocks. Some are called Leproloma; they are
difficult to distinguish without chemical analysis. |

Normandina pulchella [pretty, little]. |

This tiny
and very unusual lichen resembles a little bluish-gray saucer, and
can be found, usually over mosses, on the bark of the bases of
conifers. The thallus is a single concave disk. This is one of our
very few lichens that are not Ascomycetes; they belong to the
Basidiomycetes, the group of fungi responsible for making mushrooms
and toadstools. |
