0 a grey, green, or yellow plant-like organism that grows on rocks, walls, and trees --
1 a type of organism that consists of an alga (= plant without leaves or roots) and a fungus (= plant without leaves, flowers, or color) growing together --
Mosses and lichens occur in the vicinity of small ephemeral watercourses.
The exposed bacteria and lichens were accommodated in specially designed anthropogenic hardware manufactured to endure the space environment.
Ever since terrestrial biology became a significant field of research, a detailed monography on lichens has been missing.
A remote sensing methodology for monitoring lichen cover.
Reproductive strategies, relichenization, and thallus development observed in situ in leaf-dwelling lichen communities.
Furthermore, as a result of these uprated properties, the lichen is highly desiccationtolerant, which is a prerequisite for its occurring above ground.
Lichen from the breccia outcrop was analysed for reference.
Maximum diameters of a crustose lichen mean that many small areoles or lobules form a conglomerate of thalli.
