Can anyone help me ID these?

Found these today at about 9,000 ft. Some were funnel shaped and some weren't. White to yellowish top. Gills that run down the stem a good ways, then a distinct fleshy line (sorry, don't know the terminology). Thanks

So to me, I'd say based on pic that it is Catathelasma ventricosa 8-18 cm cap width or imperiale which can be up to 35cm across. If the flesh is hard an lacks a nice spicy order (which would be an idicater of White Matsutake, Tricholomoa magnivelare), then I'd say it ventricosa, BTW the term is veil for fleshy line, and decurrent for gills that run down stalk as these do. Also its stated as edible but tough, and smells farinaceous tastes disagreeable, I still haven't figured out that smell, which some people cannot? Hope this helps.

Also try to include where you found ie: on ground, on wood and if so what type found under pines, aspen etc, also helps to have a pic in nature, very helpful! Thanks.
