Spilonema maritimum
The thallus of "Spilonema maritimum" is made of radiating filaments that form olivaceous brown rosettes measuring in diameter. Its asci are eight-spored, with dimensions of 30–42 by 10–13 μm. The ascospores are ellipsoid, measuring 7.8–8.9 by 3.6–3.9 μm. The results of standard chemical spot tests are all negative, and thin-layer chromatography confirms the absence of secondary chemicals. In addition to various locations in Alaska, the lichen has also been recorded from Haida Gwaii and Vancouver Island, British Columbia.
