Name: Cladonia pyxidata (L.) Hoffm.
Pronunciation: Cladonia pixidata
Conservation Evaluation: Least Concern
Body Type: Cladonia - squamulose
Description: It is similar to Cladonia chlorophaea. The podetia are pale green-grey to white and range from 1 cm to 3 cm tall, although some specimens have been recorded with a height of 4 cm. The cups are deep. Small squamules cover both the inside and outside of the podetia. The primary squamules are regularly 4 mm long and vary in width from 2 mm to 10 mm. Apothecia are rare.
Chemical Tests: Thallus is negative for all tests except Pd (red).
Nature Notes: Found growing on rotting logs or well drained soil with a high humus content, fence posts and open heathland. Cladonia pyxidata can be easily confused with C. chlorophaea or C. pocillum.
