Inoculation experiments showed that Puccinia bromina var. paucipora produces aecia on Pulmonaria officinalis subsp. obscura and Symphytum tuberosum in Czechoslovakia, and also on Symphytum officinale in Norway. Hosts of the dikaryotic phase include Bromus inermis, B. ramosus subsp. benekenii, and B. secalinus (the latter known only experimentally).
