Bolbitius vitellinus - I think? (Pics)

Just found an interesting looking fungi on some woodchips. He caught my eye because he was so yellow.
I picked him up, put him in my binder (cause I was walking back from class), and when I got home I tried to pick it up, but the cap was so viscid that it stuck to the paper and pulled the cap right off!!! 
Anyways:
Cap: 4cm, viscid, yellow margin grooved Stem: yellow, 8cm in length, .5 cm in width, hollow, fragile Habitat: Growing off of pine (I think) wood chips Spores: pale Gills: light yellow, close, and not attached

Today I got to use a microscope. I sampled a few of the gills of the mushroom and looked at the spores. They were indeed rusty brown, smooth and elliptical.
I thought that was cool

100x makes the spores look like little grains of sand 
I was looking at about 440x i think. I wanted to look through the oil emursion (sp?), but couldnt

You should realize that spore color should only be determined from the color of a deposit of spores on a white background. Spore color under a microscope is often somewhat different than the spore print color. What you can verify under the microscope is that they are the corect size (unfortunately you have to calibrate first), that they are ornamented (or not) as in the description, and shaped as described. These spores should have been smooth, almost twice as long as wide, and conspicuously truncated at one end due to a large apical germ pore.
If you don't have it yet, one of the very best books on how to use a microscope for mycology is How to Identify Mushrooms to Genus III: Microscopic Features by David Largent, David Johnson, and Roy Watling published by Mad River Press, ISBN 0-916-422-09-7. It's not expensive and will tell you more than you probably want to know.
Having said all that, your mushroom certainly looks like it could be Bolbitius vitellinus. Nice find.
Happy mushrooming!

Thats really weird. I was wondering about that, and how you probably wouldnt get the correct color just from the spores under the microscope.
It was interesting because these spores were just how they were described in Arora's guide. I had looked at the spores, gone home and then realized that they were very smooth, elliptical..(yes, about 2x long as they were wide), and I didn't get close enough to see the apical germ spore.
Overall description fits perfectly as well...a lot of the specimens that were growing were falling over and being eaten away from what looked like just being so damn fragile. Fell apart in my hands practically. The stem broke right hwne I picked it!
Says they are edible (well, just NOT poisionus) however not really much to eat. I jsut threw it out. It was pretty cool walking back from class and seeing a bunch of yellow mushrooms growing together
