The cyanomorph and photosymbiodemes are here reported for the first time for Ricasolia virens (With.) H.H. Blom & Tønsberg comb. nov. (≡ Lobaria virens (With.) J.R. Laundon). The cyanomorph of R. virens is dendriscocauloid. The observed early developmental stages involve (1) a free-living cyanomorph and (2) a photosymbiodeme composed of the cyanomorph supporting small, foliose, chloromorphic lobes. Whereas the chloromorph continues to grow, the cyanomorph decays and disappears leading to the final stage (3), the free-living chloromorph. Secondary cyanomorphs emerging from the chloromorph are not known.
