Order: Peltigerales       Family: Lobariaceae Species: Sticta dufourii (green morph) Growth type foliose. Identified by Andy Acton Photos: On Oak, Glengarriff woods, Co. Cork, SW Ireland. The green morph is most frequently found as a composite thallus with the blue-green, cyanobacterial morph, Sticta dufourii. When forming an independent thallus the green morph is known as Sticta canariensis s.str The smooth lobes are greyish-green, brighter green when wet, with a whitish under surface that darkens to brownish-black towards the centre. Isidia are absent, apothecia rare with red-brown discs. The free-living green morph is only found in a few locations in SW and Western Ireland and in West Scotland.
