Peltigera rufescens, commonly known as the field dog lichen or field pelt, is a species of terricolous (ground-dwelling), foliose lichen in the family Peltigeraceae. This common and widespread species has a cosmopolitan distribution , often found in dry, sunny habitats on basic soils , limestone , and nutrient-rich silicate substrates.
The total diversity of cyanolichens appears to be significantly lower than that of lichens containing green algae (chlorolichens), with cyanolichens representing about 10% of known lichen species, though this figure may underestimate true diversity as new molecular techniques continue to reveal previously unknown cyanobiont relationships.

Here the lichen was found on a siliceous wall at the edge of a forest path in an oak-hornbeam forest. It has a pale greyish crust-like thallus with dark brown/violet tinges. It has a leproid growth form, meaning that it looks like it is made of granules; the specific epithet refers to this characteristic. The thallus forms patches that are ...
Peltigera praetextata, or the scaly dog pelt lichen, is a foliose lichen native to North America, Europe, and Asia. [1] It is defined by small belly-button-like growths called phyllidia on its edges and centre.
The lichen forms small, blackish rosettes with ruffled margins and prominent veining, features that help it thrive in submerged or semi-aquatic habitats. Three genetically distinct lineages are now recognized within the species, corresponding to eastern North America (var. hydrothyria) and western North America (vars. gowardii and aquatica).
Together, the video clips in the study had more than 12 billion views, Asia for Animals’ Social Media Animal Cruelty Coalition (SMACC) says. The report look at hundreds of posts over an 18 month ...

Lichens and nitrogen cycling – some lichens (in particular those with cyanobacteria as a photobiont) can fix nitrogen. [26] Lichen biogeography – the study of the current distribution of extant lichens and the reasons for those distributions. [30] Lichen resynthesis – lichens can be artificially "recreated" by combining partners in a lab ...
