Description

    Primary thallus made of  scattered basal squamules up to 1-2 mm long, indented, upper surface grey-greenish, lower surface whitish, sometimes persisting. Secondary thallus  made of podetia forming small dense bushes, erected, axils widely open, squamulose towards the base, shortly branched and spiny in upper parts, reticulate and spotted, grey-greeenish when moist and grey-brown when exposed to sun; sometimes potedia end in a narrow cup-like structure consisting of a single perforation surrounded by short spines, subsequently one of these spines may proliferate to form an additional extension, a process which may be repeated several times. Apothecia usually rare, ± corymbose on terminal spines, globose, dark brown. Photobiont : trebouxioid. C-, K-, KC-, Pd-, UV+ white. Relatively rare in our prospection area, in Calluna acid heathlands with or without trees, sometimes on dead wood. Not to be confused with Cladonia furcata much more common, thinner and Pd+ red and UV-  and with Cladonia gracilis of which podetia are not perforate and with a very narrow cup and  Pd+ red.
