Endophyllum cf sempervivi on Aeonium spec.

detail

gall

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.

host plants

Crassulaceae, oligophagous

Echeveria; Jovibarba globifera & subsp. arenaria + hirta; Sempervivum arachnoideum, calcareum, montanum, tectorum, wulfenii.

As demonstrated by the pictures above, this, or a closely related, species also occurs on Aeonium.

notes

Can destroy the plant. Only the leaves that have been formed in early summer are affected. Diseased leaves are highly attractive to aphids.
