Tuckermannopsis ciliaris

Tuckermannopsis ciliaris is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. It was first described by Erik Acharius in 1810, initially classified in the genus Cetraria. The species was later reclassified into the genera Nephromopsis and then Tuckermannopsis, with some researchers proposing that certain cetrarioid genera, including Tuckermannopsis, should be merged into Nephromopsis. However, this suggestion was disputed, and both names, Tuckermannopsis ciliaris and Nephromopsis ciliaris, are used in recent literature to refer to this species. Tuckermannopsis ciliaris is widely distributed across temperate regions of North America and the northern Old World, found on birches and coniferous trees such as pines, with varying frequencies and habitats across different regions. The thallus grows in irregular shapes or rosettes up to 5 cm (2 in) in diameter, with olive-green to greenish-brown coloration and elongated lobes featuring black, hair-like cilia ......read more on Wikipedia.
