Cyphellostereum ushimanum

About

Cyphellostereum ushimanum is a species of lichen-forming fungus in the family Hygrophoraceae. This basidiolichen was discovered and described in 2022 from a single location on Amami Ōshima island in Japan, where it grows on the bark of Japanese cedar trees. The species has microscopic feeding structures (haustoria) that penetrate its cyanobacterial partner, a feature that required an update to its genus, Cyphellostereum. The lichen produces small, white, paper-thin reproductive structures adjacent to its bluish-green thallus.
