Gallowayella weberi

Gallowayella weberi is a species of corticolous and saxicolous (bark- and rock-dwelling), foliose lichen in the family Teloschistaceae.

[4] After a couple more proposed generic transfers, to Oxneria[5] and later to Xanthomendoza,[6] Kondratyuk, Kärnefelt, and their colleagues finally reclassified the taxon in the then newly circumscribed genus Gallowayella in 2012.

[4] Gallowayella weberi is a foliose lichen that forms small thalli up to 4 mm wide, which adhere to surfaces ranging from closely to somewhat loosely attached.

Rhizines, which are root-like structures helping the lichen to anchor to its substrate, are mostly present and are white in color, turning yellow when exposed.

Pycnidia, an asexual reproductive structure, are common on the surface (laminal) and are orange in color, measuring about 0.1 to 0.2 mm in diameter.

[7][6] Gallowayella weberi is found in arid environments and can grow on diverse substrates including both natural surfaces like bark and rock, as well as on artificial ones such as concrete and tombstones.
