Thank you! I'll update the post with these as the leading suggestions. Lepiota seems like a reasonable genus for specimen 3 to me given the scales on the cap. I originally looked at Phelbia incarnata as a possible ID for specimin 2 as well, but I thought that the coloration and the way that the edge of each shelf seems to have a frilled margin were a bit off. Maybe its just a highly variable species or a related species of crust fungi? Either way, you are in the lead! Thank you!
