Splash CupsCyathus striatus
This fascinating little Birdsnest fungus grows on mulch. The spores are located in the little "eggs" (spore sacs) which are ejected when hit by falling raindrops. One of my students spotted a cluster of these fungi during an outdoor activity and she became very upset. I couldn't understand why she would freak out over a fungus until she started saying something about a wasp nest on the ground. It took me awhile to convince her they weren't harmful!
