"A podetium is defined as a lichenized, stem-like portion (stipe) bearing the hymenial discs, and sometimes conidiomata, in a fruticose, simple or compound apothecium. The terminal structures commonly called apothecia on podetia or other ascomatal stipes in lichens are not whole apothecia but separate hymenial discs of a polydiscoid ascoma. In spite of superficial similarity in gross morphology and phenolic composition, the cladoniform lichens are a life-form group rather than a taxonomic entity."]

"In the alteration of a rock, the most active lichenic species are those whose thallus adheres best to the substrate, but all species have an intense effect in destroying the primary minerals (calcite and dololmite) of the rocks." The authors also conclude that "... in the present case, the oxalic acid is the substance present which has the highest activity in the alteration of the rock, and that the secondary products formed by its action depend on the cations present and the state of hydration of the rock."]
