Found on SFSU campus by Dr. Desjardin, and brought into his bio 800 class. They have a fiberous veil, and a dull brown spore print. I have some photos of the spores, and the ixocutis of the pileipelis. With that, and the over all whitish tone of the mushroom, that doesn't darken towards to the base, this keyed out to H. kauffmanii in the monograph of the Western Veiled Hebeloma of the US. Although they note that these don't have any taste or odor of note, which I didn't check at the time. So, there is some question. But with over 100 veiled hebelomas in the monograph, and they are all small, light brown, not very descipt... it is a little hard to be sure on these. But it is the best I can do...
