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 ...
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.

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. [82]
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 ...
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.
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.
Lichen. Lichenology is the branch of mycology that studies the lichens, symbiotic organisms made up of an intimate symbiotic association of a microscopic alga (or a cyanobacterium) with a filamentous fungus.
