Peter Russell found these. I thought they were Entoloma (Nolanea) verum which we have found every year in the same area. The specimens had the typical umbo of an Entoloma, a brown cap, pinkish gills (from spores developing), and white mycelium at the mushroom base. What tweeked our curiosity though, was the yellowish stipe. Peter thinks it may be a Pluteus admirabilis, which is also pink-spored and with white basal mycelium, but I am not sure about that as the specimens were growing on the ground, while Pluteus always grows on decaying wood. Of course, there might have been wood beneath the ground to which the mushrooms were attached. We didn't check it out. Also, Pluteus admirabilis has a bright yellow cap and tends to appear later in the season. What neither of us did was look deeply into the gills to see the attachment. Had we noticed a 'race-track- around the stem we would know that we had a Pluteus. So I guess we have learned a lesson - to carefully and complely examine a mushroom before assuming we know what it is. Oh well, next time.
