jubulaceae
Frullania
Frullania sp. - This small liverwort is usually reddish-brown to sometimes greenish and typically inhabits tree trunks and rocks in suitable habitats. The gametophyte (pictured here) is closely adhered to the substrate and spreads by creeping along in an irregular branching pattern as it grows. The lobules on this genus are quite distinctive in that they resemble an inverted teacup on a short stalk attached to the leaf base. Rotifers and other small invertebrates can often be found inhabiting these lobules.
porellaceae
Porella
Porella pinnata L. - This attractive liverwort is fairly common on tree bases, roots, pneumatophores, and similar stable substrates in boggy to wet sites across much of east Texas, usually at or very near the average water line. In some cases it can be found higher up on the lower branches of trees which can be an indication of higher water levels.
