SPECIES FACT SHEET Common Name: n/a Scientific Name: Umbilicaria scholanderi (Llano) Krog Recent synonym: Agyrophora scholanderi Division: Ascomycota Class: Euascomycetes Order: Lecanorales Family: Umbilicariaceae Technical Description: Thallus umbilicate foliose, to cm diameter Upper surface dark brown to black, with white crystal-like deposit in center Lower surface black, with rhizines Apothecia common, smooth, without central sterile button or fissures Distinctive Characteristics: 1) lower surface with rhizines 2) apothecia smooth, without central sterile button or fissures Life History: Little is known about the life cycle Ascospores from the apothecia must join the appropriate green alga to form a new lichen thallus Thallus fragments could act as clonal propagules Range, Distribution, and Abundance: It is unclear if this species is found in the Pacific Northwest McCune & Geiser (2009) record it for the Olympic Peninsula, based on a collection from Mt Ellinor, Mason Co., cited in Thomson (1979) and appearing in the US database Although Thomson cites it as also being in WIS (Wisconsin State Herbarium database), it does not appear in that database No other records from the Pacific Northwest were found in private collections, Olympic National Park or the Consortium of Pacific Northwest Herbaria databases It is on the Checklist for the Lichen-forming, Lichenicolous and Allied Fungi of the Continental United States and Canada, Version 21 It is on the Washington Natural Heritage Program List of Endangered, Threatened and Sensitive Species Habitat Associations: arctic-alpine, on rock Threats: Mountaineers and rock climbers could break and destroy thalli by stepping or rubbing Warming climate is a risk to all lichens restricted to the alpine zone on mountains (Geiser & Neitlich 2007) Not only lichens spread into unoccupied new habitat slowly, but in the case of the alpine zone, there literally is no farther up they can go When the climate becomes too warm for survival, the species will be extirpated from Oregon and Washington and will remain only in arctic regions that provide the critical habitat Conservation Considerations: Search arctic-alpine habitats for this lichen If any sites are found, immediate protection is recommended Conservation Rankings: Species is globally ranked G1 (NatureServe 2017) and S1 in Washington (Washington Natural Heritage Program 2017).)
