gall

Most, not infrequently all, fruits in the inflorescence are browned, misshapen and remain small. The infestation is not systemic, a plant therefore can bear both normal and galled inforescences. The same fungus, or closely related forms, may cause serious damages to other plants, mais in particular. Thu fungus is the source of several myxotoxins. The gall on Plantago lanceolata seems to be quite common, but has seemingly been overlooked in the cecidological literature.
