The thallus, which is more or less effuse, and internally has oblongo- cylindrical gonidimia, occasionally becomes nearly evanescent. The sti- pites are very weak, and consequently more or less flexuose; while in old age they are denudate and become brown or blackish The apothecia when present (for the thallus is very frequently infertile) are numerous, scattered, or crowded.
