Endophyllum species have but two spore stages: spermogonia and aecia. The spermogonia are largely sunken into the leaf tissue, only protruding as small, brown cones. Infested leaves often are strongly elongated.
Can destroy the plant. Only the leaves that have been formed in early summer are affected. Diseased leaves are highly attractive to aphids.
