COSEWIC assessment and status report on the mountain crab-eye, Acroscyphus sphaerophoroides, in Canada: CW69-14/734-2016E-PDF

"This charismatic lichen forms pale gray to yellow gray coral-like cushions. It is globally rare and there are only eight known occurrences in Canada. All are within British Columbia in a very restricted climatic zone, which lies between the hypermaritime conditions found on the outer coast and the continental climate of the interior. There is a low IAO of 32 km2 and the total estimated population for this lichen is less than 250 colonies. However, this lichen occurs in remote, inaccessible sites within the rugged Coast Mountains, and additional new occurrences are likely to be discovered. In Canada, it is found primarily on dead Mountain Hemlock snags in patterned fen or bog complexes. Development pressures (roads, pipeline, hydroelectricity, mining and forestry) and climate change threaten hydrological regime and microclimatic conditions required by this species at many of the known sites"--Reason for designation, p. iii.
