I'm going to try and tackle this. After all its just a cortinarius how hard can this be. (That's a joke) I'm going with this name because its the closest description i can come up with in three field guides. I Found a whole troop of these guys growing in a mix forest of Hickory and Oak. They are a silvery lilac with a bolus stem. The stem is tough somewhat fiberouse i would call it. the young gills under neath are lilac but soon turning into rusty brown the cap bell shaped becomming umbonate as it matures.The young ones are a deeper lilac but soon turn more of a silvery lilac as they mature. I placed a drop of KOH and it turn's black over 30 minutes. Spore print is rusty brown Oder mild tast mild
