entirely covered by a thin layer of twig epidermis, usually black on either side, paler at each end of the future split, gradually eventually markedly raising the surface of the twig, becoming dark grey or black shiny, surrounded by a thin black perimeter line when dry, but totally black shiny when wet, finally opening in humid conditions but not widely by one longitudinal split in the covering layer revealing the greyish disc, pale or brightly coloured lips lining splits not observed but after the first opening, the dark inner surface of the split upper wall bent upwards out making impossible for the original split to shut fully, giving the appearance of dark lips
