Mosses


There are over 750 species of moss in Britain and they are a prominent part of the landscape on Skye.

Mosses can be divided into two main morphological groups: acrocarps and pleurocarps. These are not recognised taxonomic groups, but they are very useful for identification purposes.

Acrocarps have an upright habit, are largely unbranched and their spore capsule grows from the tip of shoot.

Pleurocarps have a prostrate habit, are always branched (sometimes bipinnate
or even tripinnate) and the spore capsule does not grow from the tip of shoot.
