A total of 464 Teloschistes chrysophthalmus (L.) Th. Fr. populations were collected, along with winter twigs from their woody substrates, in 56 of Iowa's 99 counties. This lichen is more abundant in western Iowa than in eastern Iowa and is least abundant in the northeast most portion of Iowa. T. chrysophthalmus was found on the bark of 31 distinct woody taxa, but was most frequently found on Gleditsia triacanthos.
