|The liverwort Radula complanata fruiting|
WhitecrossGreen Wood Nature Reserve just outside vice county 23 in Bucks was the venue for an informal meeting of six bryologists on Sunday 5th February. Four of us had visited the site late in December when, notwithstanding the hard frost, we had put together a good list of bryophytes and decided the wood deserved another visit. This is a brief account of what we found on this second visit. A full site list can (or will soon) be found under the ‘Local Studies’ section.
Most of the meeting was spent in the low-lying woodland which was planted with Scots pine in the 1960s but that is now being reverted to broad-leaved woodland under the management of the Wildlife Trust. In among the trees we worked up a good list of the woodland bryophytes one would expect to find in the area, with a range of Orthotrichaceae and the liverworts Frullania dilatata, Radula complanata and all three commoner Metzgeria species (M. consanguinea, M. furcata and M. violacea) on trees and typical ground mosses such as Eurhynchium striatum. On our previous visit we’d also found several colonies of the tiny epiphytic liverwort Cololejeunea minutissima growing on sallows and willows.
The broad rides provided further diversity, with bryophytes in the ditches, on exposed clay on the banks and in the grassland. In the ditches was found a small patch of the big liverwort Plagiochila asplenioides, where in a similar habitat on the previous meeting we’d also found the liverworts Calypogeia arguta and Riccardia chamaedryfolia. The exposed clay supported an abundance of Fissidens, with the common F. bryoides and F. taxifolius, and the less common F. incurvus and the tiny F. exilis.
