Diploschistes caesioplumbeus  forme parasite de Tephromela atra ou de Lecanora gangaleoides.

    Diploschistes caesioplumbeus is almost always, at least during the first stages of development, parasite of Tephromela atra and less frequently of Lecanora gangaleoides. Actually, it appears to 'absorb' these two species that vanish from the substratum. It often competes with another parasite of Tephromela atra : Lecanora sulphurea (see to Lecanora sulphurea vs. Diploschistes caesioplumbeus). Spores according to our measurements: 40-55 x 25-30 µm.
