A lichen with a shrub-like or hairy thallus attached to the substrate at a single point. [202] fruticulose Also fruticulous . A smaller version of a fruticose lichen. [202] See related: microlichen. fulvous An yellow-brown or tawny color. [43] funiculus See umbilicate lichen. funoid Made of fibers or rope-like strands. [43] furcate Forked. [213 ...
Lichens are classified by the fungal component. Lichen species are given the same scientific name (binomial name) as the fungus species in the lichen. Lichens are being integrated into the classification schemes for fungi. The alga bears its own scientific name, which bears no relationship to that of the lichen or fungus. [83]
But sometimes the parts of a lichen species common name are common names of other lichen genera. For example, Psilolechia lucida, in the genus Psilolechia, is commonly called "sulphur dust lichen". [1] [2] But "sulphur lichen" refers to the genus Fulgensia, and "dust lichen" refers either to the genus Chrysothrix or the genus Lepraria. [1] [3 ...
Usnea filipendula – one of about 20,000 described species of lichen. The following outline provides an overview of and topical guide to lichens.. Lichen – composite organism made up of multiple species – a fungal partner, one or more photosynthetic partners, which can be either green algae or cyanobacteria, and, in at least 52 genera of lichens, a yeast.

A leprose lichen, which is typically considered to be a form of crustose lichen, is one with a powdery or dust-like appearance. Its undifferentiated thallus is an irregular mix of fungal hyphae and scattered photobiont cells, lacking a cortex or any definable layers. [6] [47] Morphologically, it is the simplest growth form. [48]
A soil type or a lichen substrate rock type that is rich in or largely composed of calcium carbonate. calceolate Shaped like a slipper. [25] calcicole A plant which thrives in calcareous soil. Also calciphile, calciphyte. Antonym: calcifuge. [25] callose Hardened; thickened; callous. callus. pl. calli. 1. A protruding mass of tissue 2.
A spot test in lichenology is a spot analysis used to help identify lichens.It is performed by placing a drop of a chemical reagent on different parts of the lichen and noting the colour change (or lack thereof) associated with application of the chemical.
About one-third of all lichen photobionts are cyanobacteria, while the remaining two-thirds are green algae. [2] Some lichens host both green algae and cyanobacteria alongside their fungal component. These are known as "tripartite" lichens. In most lichens, the photobiont forms an extensive layer covering much of the lichen body (the thallus).
