A fruticose lichen is a form of lichen fungi that is characterized by a coral -like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. [1] .

2020年1月31日 · Fruticose lichens exhibit a three-dimensional structure. For example, they may be bushy, spindly, stringy, branching, swag-like or cup-shaped, but their main stems are nearly always round in cross-section.

Fruticose lichens can be pendant and hair-like, upright and shrubby, or upright and cup-like. Many fruticose lichens have round branches that have a central core and others are hollow in the middle. Other fruticose lichens have flat branches that tangle up with each other.

2016年7月27日 · The fruticose lichen is a combination of two or more organisms that cannot survive independently. It requires each other’s help to thrive. It consists of namely the fungus and algae or cyanobacteria.

Traditionally, crustose (flat), foliose (leafy) and fruticose (shrubby) are considered to be the three main forms. In addition to these more formalised, traditional growth types, there are a handful of informal types named for their resemblance to the lichens of specific genera.

Lichens are interesting organisms. They are diverse, adaptable, functional, and little understood. They play an important role in our natural ecosystems and can let us know when those ecosystems are in trouble. Lichens are beautiful, especially when you view a lichen-drenched Douglas-fir or a colorful crust-covered cliff, and up close when viewed under a hand-lens or …

Lichens can generally be classified into three general forms: crustose, foliose, and fruticose. However, there are some lichens that don't really fit into these categories as nicely, such as the "dustose" lichens that form powdery crusts.

2015年7月28日 · Crustose lichens are the most common form present in Everglades National Park and in other subtropical and tropical regions of the world. They are distinguished by their tight adherence to substrate, which makes it impossible to remove them without including part of …

Lichens occur in one of four basic growth forms, as illustrated below: crustose - crustlike, growing tight against the substrate. squamulose - tightly clustered and slightly flattened pebble-like units. foliose - leaflike, with flat sheets of tissue not tightly bound. fruticose - free …
