What are the different types of lichens?
lichens are a type of symbiotic organism composed of a plant partner and fungus. There are three main types of lichens - crustosis, foliose and fructicosis - each of which has its own shape, structure and environmental preferences. Intermediate types include, among other things, leprosy and squamulose lichen. These organisms can also be grouped according to the type of environment in which they prefer growth. Algae or bacteria photosynthesized, provide nutrients for the sponge and give the lichen its characteristic greenish or blue color. Both parts of the lichen get water and minerals from dust and rain, but some also obtain nutrients from their substrate through a mold partner.
Not all types of lichens look the same. Krustse are flat and relaxed, with close connection to their substrate, and it can be difficult to remove from the rock or the tree on which they grow. As their name suggests, the leaf -looking lichen is looking leaf -looking and are made upy with two thin leaves of mushrooms with algae in the middle. They grow in the formations of round lobes and are easier to pull them out of their substrate because they are attached only with small roots. Fructicosis or shrub lichens have small round branches made of mushroom with algae inside and an unusual formula of vertical growth that may look like beard or resemble a small shrub.
Other types of lichens include Lepras lichen, which forms powder, mostly unstructured mass without smooth surface. Placediid lichens are on the edges of lobed or not connected and closely attached in the center, making them an intermediate product between the lichens of Cvres and Foliose. Another middle form, a squamulose lichen, has many small lobes. Dimorphic lichens have the properties of bosquamulose and fruticose lichens with small lobes that carry small stems or branches.
Environment Group Divide Licomers into Seven Maincategories. Several types of lichens grow on plants and are called epiphytic. This group includes corporate lichens that prefer to grow on tree trunks, as well as ramicolous lichens that inhabit twigs. Musicoccol lichens grow on live moss and foliicol lichens prefer evergreen leaves. Both of these types are ephaphytic, but legnicolous, saxicolid and tericolous lichens that inhabit wood, stones and soil are not epiphytes.
