Peltigera praetextata, or the scaly dog pelt lichen, is a foliose lichen native to North America, Europe, and Asia.[2] It is defined by small belly-button-like growths called phyllidia on its edges and centre.[3][4]
Characteristics
Peltigera praetextata has flat lobes up to 5 cm (2 in) long, and often forms circular growth patterns.[2] It is dark green when wet, often with a reddish centre, and greyish when dry.[2] It is tomentous, or covered with fine hairs.[2] It does not reproduce vegetatively using isidia or soredia like most lichens, but using phyllidia.[3][4] It is often fertile as well, with round to saddle-shaped red apothecial discs.[2][4]
Ecology
Although often found over moss or tree bark, P. praetextata may also be found on bare soil. It is common throughout temperate and boreal ecosystems.[2]
