The lichen's vegetative body measures 3–4 cm (1.2–1.6 in) long, occasionally reaching 7 cm (2.8 in), [5] forming foliose to somewhat tufted bushy growths that attach very loosely to the surface. [10] Despite being a foliose lichen, H. catawbiensis has a growth pattern that makes it resemble a fruticose (bushy) form. [11]
Cladocetraria is a fungal genus in the family Parmeliaceae.It contains the single species Cladocetraria minuscula, a fruticose (shrubby) lichen.The genus was established in 2023 based on morphological and molecular studies that distinguished it from related genera.
The lichen fragment is pressed on the paper, and lichen substances are extracted with 10–20 drops of acetone. After evaporating the acetone, the lichen substances are left on the paper in a ring around the lichen fragment. The filter paper can then be spot tested in the usual way. [22]
Basidiolichen mycobionts consist of 172 known species (0.9% of the total number of accepted lichen species) across 15 genera, 5 families, and 5 orders within the class Agaricomycetes in the fungal division Basidiomycota. [1] The majority of described basidiolichen mycobionts belong to the genus Cora, followed by the genera Dictyonema and ...
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.

The FDA recalled 60 doughnut products, totaling more than 2 million cases, for potential listeria contamination. The doughnuts were sold throughout the U.S. and Canada.
Over 800 lichen products of known chemical structure have been reported in the scientific literature, and most of these compounds are exclusively found in lichens. [1] Examples of lichen products include usnic acid (a dibenzofuran ), atranorin (a depside), lichexanthone (a xanthone), salazinic acid (a depsidone), and isolichenan , an α-glucan .
