You are totally right, gully.moy! I'm usually more precise on those features, but I guess I've missed this one. Plus the rusty, adnexed gills are not an identification mark for Omphalotus. Therefore Cortinarius seems be the best way to go.

Nah, Omphalotus species have broadly decurrent gills (i.e. they run down the stem). Also your species show a cortina - a web like veil between the cap margin and the stem, which isn't present in Omphalotus. You may have guessed, the genus Cortinarius is named after this feature although some other genera including Armillaria can display similar veils.

Coudn't it be an atypical Omphalotus olearius (Jack O'Lantern)? See last photo of this site: http://www.hlasek.com/omphalotus_oleariu...
Otherwise Cortinarius could be a good option, gully.moy!

I guess it could be Armillaria gallica, a type of honey fungus if it's growing from wood just beneath the ground such as roots, but I think it is more likely a Cortinarius species.
