Synonym: Ramalina dasypoga.
Ramalina sorediosa is a fruticose lichen species characterized by its pale green to yellowish-green thallus, typically 3-8 cm long, with numerous cylindrical branches and powdery soralia on the surfaces of the branches. In East and Central Texas, it is commonly found growing on trees, shrubs, and fences, particularly in open woodlands and along roadsides, often in areas with full sun to partial shade. The species tends to thrive in regions with moderate to high humidity and is frequently associated with other lichen species such as Cladonia and Parmotrema.
Fruiticose lichen Ramalina sorediosa(?) on a tree on Alligator Branch section of Lone Star Hiking Trail in Sam Houston National Forest near Huntsville. Texas, February 17, 2019
Lone Star Hiking Trail, Huntsville, TX 77340, USAThe fruticose lichen Ramalina sorediosa was observed growing on a tree in the Alligator Branch section of the Lone Star Hiking Trail in Sam Houston National Forest near Huntsville, Texas, on February 17, 2019. This species is typically characterized by its bushy or shrub-like growth form and the presence of soredia, which are small, powdery masses of algae and fungal hyphae that can be dispersed to form new lichens. The observation in East and Central Texas suggests that Ramalina sorediosa may be more widely distributed in the region than previously thought. Further study is needed to confirm the identification and determine the full range of this species in the area, as well as its ecological role and potential interactions with other organisms. Additional observations and collections are necessary to fully understand the distribution and characteristics of Ramalina sorediosa in East and Central Texas.
