Chasmoendoliths

Chasmoendoliths and cryptoendoliths can affect the substrate by water retention. Their metabolic products are released into the microenvironment and may contribute to carbonate dissolution ( algues cariantes). True endoliths, or euendoliths, are those that penetrate actively into the interior of the substrate forming tunnels which follow specific boring patterns (Golubic, Friedmann and Schneider, unpublished results).
