|Sussex Teloschistes chrysophthalmus|
· In 1994, it had been discovered at Slapton Ley, but the bush on which it grew was cleared as part of conservation scrub clearance.
· Next, it was found on a hawthorn bush on the shores of the Drift Reservoir in Cornwall, but when the water level rose and submerged the bush, its only known modern site was once again lost.
· More recently it was found on a branch fallen from an apple tree in Herefordshire.
Not a very promising situation for its continued survival, but shortly after that, it was found in County Cork and as far as I know, that site is still extant. It also occurs on Guernsey on two bushes where I saw it recently. In Jersey however, it was last seen in an orchard back in 1966. A recent trip to the site confirmed that all the apple trees had gone.
On Boxing Day I met up with Mark Jackson and he showed me the two bushes each with just one Teloschistes chrysophthalmus. We had a good look round at other trees, but found no more. However, on our way back to the car, Mark found a minute, pink lichenicolous fungus growing on a twig. I photographed it, and sent off the photograph to the experts. It is Illosporiopsis christiansenii and new to Sussex. Mark is lucky in having an excellent eye for lichens, as well as a great enthusiasm for them.
