I’ve not been out in the field much over the summer at all, and when I have it has largely been for a short flurry while doing something else. Even so, if armed with the list of common species not yet recorded in a locality it is usually possible to pick up a few new tetrad records.
Yesterday I was out with the Sussex Fungus Group at Rowland Wood and took the opportunity to record a small number of bryophytes in passing. So, it was hardly a thorough survey, but there were already 78 species recorded for the tetrad, including those Tom had recorded there in 2012.
Quite near the beginning of the walk a small sandstone stone in a damp ditch had some Tortula muralis on it, which was new, though I then got caught up in the fungi search and neglected the mosses for a bit. There were several very significant clusters of Armillaria tabescens (Ringless Honey Fungus) on the heath, and I got to try the flavour of the milk from the very well-named Lactarius pyrogalus (Fiery Milkcap), which is not an experience you get with bryophytes. It was fabulously hot!
A little later on a willow was home to a nice cluster of epiphytes: Radula complanata, Metzgeria violacea, Cololejeunea minutissima, Ulota phyllantha and Orthotrichum pulchellum, the latter two being new records.
The edges of a fire site had mats of Pseudephemerum nitidum and several colourful ascomycetes typical of that habitat, and many damp ruts also had a dusting of Pohlia melanodon. A large decaying old Beech attracted the attention of the mycologists but didn’t look very promising for mosses. However, on very close examination it had a few very small fruiting clumps of the Orthotrichum affine. Thanks to Tom Ottley for correcting my earlier mis-identification of it!
Finally, on the way back to the car there were patches of Didymodon insulanus among the gravel, bringing the tetrad total up to 83. I really must get out more…
