It is an obligate plant parasite on Crepis pyrenaica, a member of the hawksbeard plant genus Crepis. The species was found on a specimen of C. pyrenaica found in Germany. The species name, which comes from the full ceremonial name of the city of Bangkok in Thailand (with the end suffix -nonopsis meaning "not like", as the authors did not consider the organism to visually resemble the city), is the current longest species name, with 181 characters.
