Identification: Unique and delicat mushroom ID requested

I have a few books on mushrooms and have yet to identify this one. Found this morning, there were delicate to the touch and actually closed or fell if touched. A few hours later they were practically gone. Anyone have a clue on this one?

 

Have no idea on the ID

That particular color is one of my favorite colors for fungi. I photographed some that were teenier in the redwoods, with almost the same colors. Cone shaped cap though.

The yellow stems look so attractive, expecially against a needle backdrop.

 

Is it possible this is an unidentified species?

 

Yellow fieldcap (Bolbitius vitellinus).

I don't believe so, note the ring and slenderness of the stalk. It is also not a robust mushroom as stated. Life span is one night only.

 

Possibly a Mycena?
The blown out cap shape looks less Mycena-ish and more Coprinellus-y, however this looks more white spored.

 

I also just found a similar mushroom in Greenville SC a few days ago and was trying to ID it when I found your site. It popped up overnight and looks like a flower. Here is a picture. Thought I would check Audubon's Mushroom ID book next.

 

The fungus, now from two localities, indeed possesses a ring. Apparently, it also has white spore color. No doubt it is closely related to Leucocoprinus birnbaumii (Lepiota lutea). However, it would appear to be different through the very delicate appearance and short lifespan, as well as occurrence outdoors. I do not know this fungus.

Thank you for your info. I searched images of Leucocoprinus luteus and this photo seemed very similar. It is in a foreign language, so I can only read the names. Here is the link: http://www.gdfs.gov.cn/rdgz/ShowArticle.asp?ArticleID=1494. What do you think?

 

Photogirl and Harri: It looks like Leucocoprinus fragilissimus to me:

This species was originally described from South Carolina.

Thank you for your information. It is very interesting to me that this was first discovered in SC. Had I known it only lasted a day and would be so elusive, I would have taken more photos!
