foliose thallus
Quick Summary
A foliose thallus is a biological structure found in organisms like lichens. It is characterized by a flat, thin, and often lobed form that attaches to a substrate. The thallus is the plant body of simpler organisms such as algae and fungi, lacking the specialized tissues like stems and leaves found in higher plants. In lichens, which are symbiotic associations of algae or cyanobacteria and fungi, the thallus is the composite body. Foliose lichens are distinct from crustose (crust-like) and fruticose (shrub-like) lichens, typically having a clear top and bottom side and attaching to surfaces at their center.123

fungusBasic features of lichensFoliose, or leafy, thalli grow best in areas of frequent rainfall; two foliose lichens, Hydrothyria venosa and Dermatocarpon fluviatile, grow on rocks in freshwater streams of North America. Fruticose (stalked) thalli and filamentous forms prefer to utilize water in vapour form and are prevalent in…
