Lecidella stigmatea

Found on the north side of a limestone ridge. The apothecia lacked a thalline border narrowing down to a lecideine species. A thin section in water showed the exciple to be a blue colour typical of Lecidella stigmatea. The KI reaction to the ascus was difficult to see properly but did show to be lecanora type when for a split second as the Iodine hit the apothecia. It then displayed as in the picture below.
