This fungus is ruining my lawn

Hi everyone, hope I've put this post in the right topic.
Can someone please identify this fungus and tell me how to get rid of it.
Our house is 5 years old and a tree was obviously felled to make way for it, but the old stump is partly under a dry stone wall, on the other side of the wall the fungus is sprouting there as well.
It is very unsightly and seems to bloom and die within a day but comes up again. As you can also see it comes up under the gravel as well.

help needed please a.s.a.p.

 

Can you get a close-up of one of the toadstools? It looks sort of familiar but I can't be sure from that pic.

 

Do u think it could be this:

can't see how to get rid of it if it is. It says that it's poisonous and is present from May to Dec.

 

Sorry, my camera isn't the best at close-ups. They are tiny with a long pale stalk, start off a honey colour then darken, finally going black and literally dissolving.
I've poured allsorts on them to no avail.

 

Thanks Marley, but I don't think it's Coprinus Astramentarius, mine haven't got a frilly edge, I've just been out to look again and will try and get a better picture tomorrow.
I've even poured bleach over them but that hasn't helped. i could drill the stump which is at ground level, you can see it (black) on the first pic I posted and pour something into that.

My husband thinks I'm worrying about nothing but they are so unsightly and spreading fast., strange that they seem to be climbing up the wall!

 

Well the good news is that on close inspection, and from further description, I don't think my initial thought was right, ie I don't think they are 'shrooms from the psilcybin family, which are usually found in grassland and have a small pointy bit on the top of the cap.

As they are probably feeding off the tree roots, perhaps digging out the roots that are near the surface might help by taking away their food source. Fungis are remarkably resilient beasties, and I think (but could be wrong) that the most effective treatment is usually to change their environment to make it inhospitable to them, rather than trying to poison them out.

 

I was going to take a better pic but they had all gone black and dissolved, but no doubt will return any day soon!

You can't see any tree roots but the stump is just below ground level.

I can't believe there isn't something I can just pour over the lot of the flamin' things, that will get rid of them forever.
There really are thousands of them and now they have started on the other side of the stone wall where everyone can see them, it looks like 'The Day of the Fungi'!

 

there probably is but it would only be available to professional/licenced users.

try Green Thumb or some such other outfit as their operatives should be qualified

 

Thanks for replies again. I will look at the treatments mentioned.
Will this kill of the fungi and spores etc only or will it kill the grass as well?

Not too bothered about the grass really as it's only a narrow strip, I'm more concerned about the fungus spreading.

 

There arent really any trade products suitable, a few for clearing fairy rings on golf courses and a few general fungicides but these are all VERY expensive and probably wouldnt be that effective.

The sensible course of action is to dismantle a small section of the wall and get the stump ground out then reelay the wall or just put up with the fungi.

Armilatox will help to an extent but the problem will remain whilst the stump is left.
