No specimen available

These were in a grassy area in the root zone of the only Catalpa tree on the ranch. In this area, the A. pantherina are spring mushrooms(Mar-May)and the very similar A.gemmata are fall mushrooms (Nov-Dec). Both are common with a long fruiting season. They are so similar in structure that color is the only way I can distinguish between them. A. pantherina being tan (spring) and A. gemmata being yellow (autumn). I don’t have a microscope.
