Sagiolechia phaeospora is a species of crustose lichen in the family Sagiolechiaceae.[1] It is found in the alpine tundra of Alaska.
Taxonomy
The lichen was described as a new species in 2020 by the lichenologists Alan Fryday and Toby Spribille. The type specimen was collected from the Hoonah-Angoon Census Area in Glacier Bay National Park. It was found on Excursion Ridge at an elevation of 918 m (3,012 ft), where it was growing on argillite rock. The specific epithet phaeospora refers to its brownish ascospores, a feature that is unique in the genus Sagiolechia.[2]
Description
Sagiolechia phaeospora has a thin, whitish, crustose thallus with numerous cracks and areoles. The photobiont partner of the lichen is a single-celled green alga with roundish to angular cells measuring 10–14 μm. The other species in the genus, in contrast, have trentepohloid photobionts (i.e., filamentous, multicellular green algae with a yellow to orange color). The apothecia made by the lichen are black, measuring 0.6–1.0 mm in diameter. Asci are eight-spored, with dimensions of 70–72 by 16–17 μm. The brownish ascospores are more or less [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (i.e., divided by horizontal and vertical septa), and typically measure 17.8–18.5 by 9.5–10.6 μm. Sagiolechia phaeospora is unreactive to standard chemical spot tests.[2]
Habitat and distribution
The lichen is known only from the type locality, where it is saxicolous on argillite rock in heath in alpine tundra.[2]
