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.

hostplants

Crassulaceae, oligophagous

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

notes

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