Gregorella humida was found in western Oregon, U.S.A. This is a new genus and species for North America, with both fertile and sterile collections. An ITS sequence demonstrated its affinity with European material. This minute, granular to branched-granular cyanobacterial lichen is a pioneer on recently disturbed soil. The species was previously known from Fennoscandia, the U.K., continental Europe, and Turkey.
