I did not realise there were that many alien fungi in the UK, having had a bottle of wine tonight I will keep my research for tomorrow! It seemed quite at home in the culbin sands we found it on, it is a shame you are so far away otherwise I would give you a little tour of the area as it is home to a multitude of interesting fungi and slime moulds.
We were there to look for saffron and wooly milk caps but a little early for this area, there were some rather nice bolletes and russula as well as some most awesome Cortinarius violaceus growing though which in the next 4 weeks should go quite insane, perhaps even the occasional cauliflour too which we have occasionally found near by.
If you are up this way ever (Moray) you should have a good forage.
