Distinguishing Features

A rare hornwort with a relatively undissected thallus, it can form large populations of coin-sized matte green plants over seeping fine soils and vernal pools. At maturity the yellowed horns are less than 5cm tall and hold yellow spores.

Similar species

Lacking the bulbils of Phymatoceros bulbiculosus and possessing yellowed horns at maturity, P. pearsonii could only be mistaken for Phaeoceros oreganus. The distinction is microscopic and based on the colour and ornamentation of the spores.
