Trumpet lichen

Cladonia fimbriata has relatively tall trumpet-shaped podium-like structures or podetia. The podetia rise like small tubes and abruptly open out trumpet-like, which is a distinguishing feature. The reproductive structure or apothecium resides at the top of the podetia. The podetia range from 1 cm to 2 cm in height and are usually coated in a fine dust of soredia. Sometimes the soredia form larger granules, but this is rare. The rims of the podetia are even, unless they are actively reproducing, in which case the apothecia make the rim lumpy or irregular. The thallus is a grey-green to green colour. Scales or squamules with a small indent, giving them a lobed appearance, cover the thallus, but not the podetia. The squamules may be sorediate or dusty.
