Gallowayella hasseana, the poplar sunburst lichen, is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae.[2] It occurs in North America.
Taxonomy
The lichen was first formally described as a new species in 1944 by Finnish lichenologist Veli Räsänen as Xanthoria hasseana.[3] Over a half-century later, it was transferred to Xanthomendoza.[4] Sergey Kondratyuk and Ingvar Kärnefelt proposed a transfer to genus Oxneria in 2003.[5] In 2012, the genus Gallowayella was circumscribed, and this species transferred to it.[6] The species is commonly known as the "poplar sunburst lichen".[7]
Description
The lichen has a yellowish-orange thallus comprising small, overlapping [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (measuring 0.3–0.9 mm wide) arranged in a loosely attached rosette. The thallus undersurface is white, and attaches to the bark [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] by relatively long rhizines. There are neither isidia nor soredia on the thallus surface. Apothecia, usually numerous in the center of the thallus, have dark orange [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and are 0.6–3 mm in diameter. Ascospores are ellipsoid in shape with a single septum, and have typical dimensions of 15.5–18 by 7.5–9.5 μm.[7]
Gallowayella hasseana mostly grows on bark (especially poplar bark), although it has occasionally been recorded on rock or on wood. It prefers open or partially shaded areas.[7]
