Description
Speckled shield lichens is a captivating group of foliose lichens known for their broad, leafy thalli that adhere closely to their substrates. These lichens typically grow on tree bark, rocks, and occasionally on soil, thriving in a variety of environments from forests to urban areas. A notable feature of speckled shield lichens species is the presence of tiny, dot-like structures called pseudocyphellae on the upper surface of the thallus, which aid in gas exchange. Speckled shield lichens plays a crucial role in nutrient cycling and serves as an indicator of air quality.
