No specimen available

Found this in my backyard in the lawn. I’m interested to know if it’s safe for dogs to eat.

I was skeptical about the galerina poisoning, but you were right, Paul.

there was a probable case reported on the Cornell Mushroom Blog (are you aware of another?), and the mushrooms were IDed by Cathy Hodge. But galerina are wood rotters not grass dwellers; if there are not trees in or near the lawn, it is unlikely that the ground contains the well-rotted wood necessary to fruit these tiny deadly mushrooms.

There’s another deadly threat to dogs in the way of lawn mushrooms: Galerina marginata. Pholiotina might be a concern, too, but there is at least one documented canine death caused by G. marginata.

those are pretty mature fruit bodies…

…but the primordia, which I didn’t notice at first, ARE brown, and certainly viscid. And gosh, turns out terrestris does have cobwebby veil remnants.
white terrestris: whodda thunk it?
you could be right, doug…and good news for the dog owner: they are listed as “edible,” ie not toxic.

P. terrestris starts out very pale.

These here are very small, and young small P. terrestris starts out very pale. In grass in California in this season the greatest chance for these is to be P. terrestris. Viscid cap, shaggy stipe, brown spores… True with just this photo to go on, there is a large chance it is something else, but I’d say the greatest chance for id here is for P. terrestris.

For dogs eating, yes Amanita is the main concern, there is also some concern about the Scleroderma, but that might have been pigs munching up the false puffballs, which aren’t these in anycase. If you are concerned about dogs eating stuff, take a look at some Scleroderma species so you can recognize those also. Oh, and what was it, Debbie you had a case of a dog eating a Paxillus? Take a look at those species too, so you know what to look for.

P. terrestris might be an unknown eatability, but as an unknown they at least haven’t come up as a poisoning concern either.

too pale, wrong veil for terrestris.

OK, this one is a mystery, and we taxonomist can argue ID forever.

and to the original poster…photo ID on some of these less than obvious mushrooms is not the way to go in poison prevention.
Edibility on many of these is unknown, but again, the mushrooms that you really have to worry about are the amanitas, which are only found with oaks (deadly species like phalloides and ocreata) and pines (strongly toxic species like muscaria and pantherina). Unless you have a puppy that eats everything, I wouldn’t obsess too much about it. Give your dog something else to do when it is in your yard unsupervised!
Most dogs will quickly vomit a mushroom that is unpalatable and indigestable; amanitas are another story…

purple gills?

Stropharia has purple gills. These are white.

Hebeloma maybe?

it looks brown spored

looks like some sort of whitish stropharia…

not a known dangerous species, but if you are concerned, don’t let your dogs eat them! most toxic lawn mushrooms would just cause your dog to vomit.
