Fungus experts?

Fungus experts?
There are a few patches of this mushroom/toadstool in the garden in areas which have been mulched with shredded woody material. They are difficult to get the true colour on camera, but it can best be described as greeny turquoise. The cap of the mushroom starts off convex but goes concave as it ages. There is a very sticky clear membrane over the cap. Anyone any ideas?  TIA.

Remembering a picture of a similarly blue, mushroom, pictured in the past by Olga Bondareva, I wonder if it is some kind of  Stropharia ?
But those are meant to have rings on the stem (stipe?) and yours does not. 

Found this though.... no ring and similar!

They certainly look the same don't they? And it even says green/azure, as much of the Italian as I could easily translate.

I linked the question to a Norwegian site, and they say "Stropharia er rett, nærmere bestemt blågrønn kragesopp Stropharia cyanea. (syn S.caerulea). De gule flekkene kommer av frost, jeg har sett det samme her."

Think you understand the answer

Should have mentioned the size, 1.5 inches in diameter (the cap) to 3 inches in the largest ones. Thanks folks. Also the thing smelled very strongly of mushroom Stropharia are described as having no scent.

The Norwegians say the mushrooms have gotten frost marks (the yellow patches). Maybe that makes them smell.
