Why suggested for a Global Red List Assessment?

This fungus is known only from a single collection where it was growing, perhaps as a parasite, on a lichen on Fraxinus excelsior. Ash dieback caused by Hymenoscyphus pseudoalbidus Queloz, Grünig, Berndt, T. Kowalski, T.N. Sieber & Holdenr. (better known by the synonym Chalara fraxinea T. Kowalski) is likely to result in significant loss of habitat as it spreads across Europe. Using IUCN categories and criteria, Cannon & Minter (2013) evaluated this species globally as Critically Endangered.

Population Trend: Deteriorating


Habitat and Ecology

This fungus grows, perhaps as a parasite, on thalli of the lichen Ochrolechia yasudae Vain., which itself grows in Fraxinus excelsior L. Nothing is known about interactions between this fungus and animals, or other fungi or plants.
