I was working on Old Castle Down this morning, and couldn't resist a quick stop to admire the fine patch of Porella arboris-vitae which grows on a lump of limestone here (spot the Mottled Grey resting on the same rock).
I was pleased to find a couple of additional patches of the Porella on adjacent rocks (highlighted in photo below - the original patch is on the right). Somehow I'd missed these on previous visits.
I also checked a nearby limestone wall, but although it was wonderfully mossy, including big sheets of Porella platyphylla, I couldn't find any more arboris-vitae.
Well done finding the extra patches - It's a species I really would like to see, so will definitely call in next time I'm down that way.
