Genus CladoniaGenus CLADONIA, Hoffm.

The horizontal thallus of the Genus Cladonia is scale-like, rarely granulose; and may or may not persist.

The fruiting branches ( podetia) are hollow, sometimes opening to the exterior; leathery, cup-shaped, or funnel-shaped; sometimes shrub-like,and very much branched; rarely club-shaped.

The fruiting organs (apothecia) are usually little heads (cephaloid) hollow within, they are variously coloured, but never black. The spores are ovoid-oblong; simple; colourless.

The generic name Cladonia from the Greek; a branch, was given by Georg Franz Hoffman to describe the characteristic habit of growth.
