Description
Ptilidium pulcherrimum is a leafy liverwort with a reddish to yellowish-green coloration and distinct deeply divided leaf margins. It grows closely to tree bark in dense patches and exhibits a pinnate branching growth pattern. Its stems are usually obscured by its overlapping leaves which are measured at 1.8 mm (0.07 in) in width and 1.4 mm (0.06 in) in length.[4]
Habitat
Ptilidium pulcherrimum is typically found on the trunks or branches of living trees and shrubs but can also be found on fallen logs or boulders.[4]
Similar species
P. pulcherrimum can be easily confused with P. ciliare. However, P. pulcherrimum is more commonly found on wood, grows more tightly to the substrate than P. ciliare. It also has deeper divisions in its leaves compared to P. ciliare.[4]
