I had a bit of time to kill on Friday while I was waiting before heading off for the weekend. Not seeming terribly promising for bryology, I had 80 minutes in Gossops Green in Crawley, so did a quick raid on Goffs Park. As it turned out, it was better than I expected, and there was only one previous record for TQ23N (for Rhytidiadelphus squarrosus), so anything was going to be an improvement.
A triangular corner of the park is managed by Gatwick Greenspace Partnership, and that produced a reasonable collection of species, including some epiphytes such as Cololejeunea minutissima and Cryphaea heteromalla on some relatively recent plantings.
The body of the park itself looked unpromising, but there is a small stream running through the middle of it, surrounded by what must be a small vestige of old woodland. However, the stream was incised enough to make it tricky to see what was in it, and I was wearing completely inappropriate footwear, so only managed to record Pellia epiphylla and Lunularia cruciata. There is no doubt more.
With time running out, a very dusty Bryum argenteum lurked on the tarmac of the footbridge over the main road. The grand total was 23 species, including Rhytidiadelphus squarrosus), and I only hit the western part of the park.
