FRUTICOSE LICHENS

Fruticose lichenFruticose lichens don't look at all like fruits. The word "fruticose" is a technical term meaning "shrubby," and many fruticose lichens, such as the one at the right, do indeed look like miniature shrubs an inch or so high. The one in the picture is on a twig, and the lichen is 3/4-inch tall (2 cm). Notice the cuplike items at the end of many of the lichen's branches. These are the reproductive cups, or apothecia, which are fungal in nature.

Another "shrubby" fruticose lichen, the Slender Orange Bush Lichen, Teloschistes exilis, found throughout the Americas, is shown below:
