Extract from Wikipedia article: Teloschistes chrysophthalmus, often referred to as the gold-eye lichen or golden-eye, is a fruticose lichen with branching lobes. Their sexual structures, apothecia, are bright-orange with spiny projections (cilia) situated around the rim. It has a global distribution, but is often localized and rare in many parts of its range. Colonies most often form along coastal areas.
Teloschistes chrysophthalmus is a species of fruticose lichen that grows as a yellowish-green to golden-brown shrub-like thallus. In East and Central Texas, it is typically found on trees, particularly oak and cedar, in open woodlands and along roadsides. The lichen's branches are slender and irregularly branched, with terminal apothecia that produce bright yellow to orange spores. It thrives in full sun to partial shade and is often associated with other lichens and mosses. In Texas, Teloschistes chrysophthalmus tends to fruit abundantly, making it a conspicuous component of the regional lichen flora.

Golden-eye (Teloschistes chrysophthalmus) and other fruticose lichens when exposed to regular daylight as well as when illuminated by a 365 nm ultraviolet (UV-A) blacklight from a trailway near Birch Creek Unit of Somerville Lake State Park. Texas, September 1, 2024
Golden-eye lichen (Teloschistes chrysophthalmus) when exposed to regular daylight as well as when illuminated by a 365 nm ultraviolet (UV-A) blacklight from a trailway near Birch Creek Unit of Somerville Lake State Park. Texas, September 1, 2024Observations of Teloschistes chrysophthalmus in East and Central Texas reveal the species' presence on various substrates, including twigs, tree branches, and stone. The lichen's golden-colored reproductive organs, surrounded by "eye lashes," were noted in multiple locations, such as Lick Creek Park and the abandoned TAMU Horticultural Gardens. The species was also found on different tree species, including oak and huisache. Additionally, observations showed that the lichen can thrive in a range of environments, from urban areas like Texas A&M University to natural parks like Somerville Lake State Park. The use of ultraviolet (UV-A) blacklight revealed the lichen's fluorescence, providing further insight into its characteristics. Overall, the observations suggest that Teloschistes chrysophthalmus is relatively widespread in East and Central Texas, with a range of habitat preferences.
