The inset in the second photo shows a number of spores. They are very slightly roughened and measure about 8-11 x 5-7 micrometres. For the moment I've put this in Thaxterogaster. For some years the genus was subsumed into Cortinarius, but more recently was resurrected, albeit to incorporate both truffle-like fungi and standard mushroom-like fungi - just as Cortinarius also includes both mushroom-like and truffle-like fungi. Some more checking in the future may see this sighting move into Cortinarius.
