taking such a close look at my observation. This area (the greater St. Louis metropolitan area which lies along the Mississippi River) is definitely not arid, nor is it alpine. The climate is considered to be “continental”, and there are no large mountains (mostly flat flood plain and gently rolling hills); so I think we can rule out C. helenae. Cyathus striatus also has a shaggy, woolly outer surface with tufts of hair (Kuo); and is very frequently seen in our area. Always appreciate your comments.

seem to match C. striatus. But I think this is C. helenae, described in Arora as: “…found mostly arid or alpine habitats, with a grayer, thicker-walled next that has tufted hairs on its exterior.” The main difference is the “tufted hairs on its exterior.” Both C. striatus an C. helenae have striate cups.
