Images of British Lichens



Vulpicida pinastri (Scop.) J.-E.Mattsson & M.J.Lai
 
(= Cetraria pinastri (Scop.) Gray)


Foliose, yellow (greener when wet), lobe margins fringed with bright yellow soralia; apothecia apparently unknown in Britain. Very scarce and declining, northern and with most sites in the Eastern Highlands of Scotland, on acidic stumps, twigs and bark, including Heather (Calluna) and Pine (Pinus), but predominantly in Britain on Juniper (Juniperus communis) and further threatened by the decline of this host (see Binder & Ellis (2008), Lichenologist 40: 63-79).

The very similar V. juniperinus, more readily fertile and bearing stalked black pycnidia, but lacking soralia, occurred in similar habitats and had a similar distribution, but seemingly is long extinct.

(was in poor condition in 2003, tending to be covered by Larch (Larix) needles from adjacent plantation, and sadly has now gone from here)
