Can anyone ID This mushroom ?

[DianeCarter]

Hi al[ATTACHMENT NOT FOUND]l,
Obviously plants and bugs are good to have in a viv, I've also read that funguses will appear, and not to worry. About a year ago I had a few small mushrooms/toadstools appear in my imitator viv for a short time--they were maybe an inch tall, brownish/tan, kinda cool to have and then they were gone. No big deal, they were actually a bit boring cause they were very plain looking.
Well, have I got a wierd thing growing in my viv! Trying to get pix attached. Bright yellow, as bright as the leucs it is in with. It appeared 2 days ago (Tuesday) very small, less than an inch. Yesterday (Wednesday), about 2 inches tall. Today (Thursday) it grew to at least 4 inches tall! If I can get my pix attached, you will see it is next to a cocohut, for reference as to size. I have pix from both yesterday and today. If you peer under the cap, it is really very intricate.
I don't know the difference between mushrooms and toadstools. I know this week in this area people are hunting morels, and collecting them by the pounds, but this is certainly not a morel--wrong color. I mention this because this must be a good time of year in northwest Illinois for fungus!?
I know some mushrooms/toadstools are poisonous, and if at all like frogs, judging from the color of this one, it might be!
As a point of interest regarding this viv, and possibly related...since I planted this viv about 6 months ago, it has had tons of "spore" looking tiny cream colored balls below the surface, amongst the substrate and leuca balls.It is very visible throught the outside glass of the viv. Poor picture (hopefully) attached.
Any ideas on identification?
Thanks.
Diane
PS: Am hving trouble with pix. Will try to add whatever doesn't post. Thanks for your time![ATTACHMENT NOT FOUND]

Diane, I don't think it's much to worry about. I don't have any background in mycology besides the basic fungal biologies, so I don't even know where to begin to properly ID it beyond a basidiomycete. These things pop up in tanks because either spores or parts of the mycelium are on things like leaf litter or wood that we use. The fungus will sit around for a while growing underground until conditions are right. At that time, it will send up a fruiting body (the mushroom you see) which will produce spores and continue the life cycle. Even if you removed what you see, the mycelium is still growing in the substrate, so it's probably best to just leave it be and let the springtails do their job

Thanks so much, Goods! I am breathing a sigh of relief. I was hoping it is not dangerous to my frogs, it is really a beautiful thing! I can't believe how fast it grew, from less than 1/2 an inch just 2 days ago to 4+ inches now. Like I said, there are tons of little "balls" in the substrate, it's got to be the spores from this. As long as it's not dangerous, I will be happy seeing these things grow from time to time. It will be interesting to see how long it lasts before it disappears. It grew so fast, I'm guessing it will disintegrate quickly too.
Thanks again!
Diane
PS: I will have happy happy springtails!

I look forward to seeing them pop up in my tanks, haven't caused any issues.

Maybe that last picture should be blurred hock:

Made me chuckle a bit.

I do not have much to offer other than saying fungi are a fairly common occurrence within our set-ups and are typically nothing to be alarmed about. Enjoy them while they are fruiting, take pictures and share with the community as you have. There are some really cool looking species out there.

[frogparty]

take a spore print, tell me the spore color, and if possible spore size via microscope measurement and Ill try to ID it for you

[DianeCarter]

Yes, I thought about blurring it, glad there are no kids on here!
Around noon today the umbrella started closing up, this is what remains tonight.
Thanks again for all your input!
