Podetium

A podetium (plural: podetia) is the upright secondary thallus in Cladonia lichens. It is a hollow stalk extending from the primary thallus.^[1] Podetia can be pointed stalks, club like, cupped, or branched in shape and may or may not contain the ascocarp, the fruiting body, of the lichen.^[2] It is not considered part of the primary thallus as it is a fruiting structure for reproduction.

A lichen can be described as "podetiate" when it forms a podetium.
