Thank you so much for all the information and I'll certainly take both of your advice! I hope to find many more fungi in the future and take several photos of them. I hope my most recent spotting was much more helpful with the angles and overall way the photos were taken! http://www.projectnoah.org/spottings/843...

You just described exactly what I feel like when I'm describing a mushroom, Alex! I want to write as little as possible, and it turns into a novel. Hahha but extra information never hurt!
Anyways, Alex's got a great point: I have not heard any strange incident in the mushroom world where someone got hurt handling them, at least in the CAPPED mushrooms. As it is I know so little about even those, and anything outside of that range is beyond me.

oh,right. that make surely sense. some should not played with,a little touch or push for position, isn't that bad. Schizophyum commune shall carry human harmfull compounds. But the most other mushrooms (mostly capped) are just toxic by ingestion. Nothing, not from other plants or animals schould come into wounds/blood, that the same as with fungi. Spores: when you not lean directly with your head above the fungi and inhale the spores directly, is it the same as the fumes of some bleaches= not healthy ,not really harmful but you should not inhale it. Mold are a other story: but you should be more carefull with molds you encounter at home, than the ones in the forest. ....... i just wanted to write a little rule/suggestion-list but it got a whole story!!! :)

Oh okay, I understand now. I don't ever recall a mushroom that has been refered to as toxic or poisonous to the touch (believe me, the guides and online sources would point this out), even the deadly ones, but an adverse reaction (allergic) could certainly occur. Sometimes even spores cause some damage! I think it's relatively safe though, some mycologists mention that it is completely harmless to touch them bare-handed.

For any kind of plant or organism I may find that's poisonous to the touch. I'll be using them to touch the organism and move it to get better pictures. I don't believe there are fungi that are toxic to touch, but you can't be too careful.

coral, maybe it is easier, to take just a little spray-bottle with desinfection (real medicinal desinfection or for the little dirt 70-98 % alcohol) with you. It is smaller, as a little pack : gloves (only 1 pair is also useless {for me, that is ! }), you will directly get desinfected (what you not have with gloves, with little holes) and you have no waist, to carry around. And sometimes you just feel fresher/cleaner, with a little desinfecting handwash! That's my opinion, i let the plastic/latex gloves at home, just one pair thick rubber-gloves, to skip some thick,dirty,rotting,fungi-covered logs (then i will some more protection {only for the gross-feeling}. good luck at mushroom/fungi-hunt. :)

Sounds like a good idea Coral. :)
What do the gloves do though?

Thanks Ivan, yes these were common which led me to believe it's Agaricus bisporus. I wasn't able to do much with the mushroom because I didn't have gloves and it's too short to get a shot of the underside without touching it. I'll definitely bring gloves every time I go hiking now.

Thank you for the suggestions Alex, I have a few other fungi spottings that I did take many different angled photos of that I will upload soon! I'll research your suggestions, but I believe it's Agaricus bisporus. Thanks for the help!

Absolutely true; a lot of species could fit the description for the cap and the location where its growing, but there is so much more to make a solid claim that it is this mushroom or that mushroom. What color are the gills? How are they attached to the stem? Are they close to each other? What spore print do they produce? What do younger and older specimens look like? How many times did you find this? Does it fruit every year? What happens if you injure it (bruishing, color changing effect)? What if you break it in half (what sound does that make)? What smell? Taste? There's a whole lot that can lead to a clear identification, but as you can see, more is needed to do this.

diffcult to see, need more picture, different angles, but the cap look like a agaricus (champignon) . The yellow staining agaricus can you easily confirm, at little injuries: cut or scratch with the fingernail. will he discolor/stain yellow after some sec/few minutes. The A. semotus is already a good guess, but also: " duldicus", "subperonatus", "fissuratus"..... as you can see, some possible others. But the most important is, please more pictures, next time. good luck

Any fungi experts? On this website:
http://nathistoc.bio.uci.edu/Fungi/Agari...
I came up with Agaricus semotus, but it also looks like a Yellow Staining Agaricus. I also believe my other spotting: http://www.projectnoah.org/spottings/829...
is a Yellow Staining Agaricus, but I want confirmation! Thanks.
