Caption: Lichen reproducing. Macrophotograph of the lichen Phaeophysica orbicularis, seen in a wet "vivid- green" state. The granular appearance on the upper surface of the fronds is produced by reproductive structures called soredia. These granular clumps break off and can form a new lichen colony. Lichens are symbiotic organisms, consisting of an algal and a fungal partner together. The fungus benefits from the photosynthetic activity of the alga; the alga may be protected from drought and intense light. Lichens may be sensitive to sulphur dioxide, like this species, & are used to monitor air pollution. (See photo B350/111 for this lichen in a dry state). Magnification: x1 at 6x6cm size.
