Gosh, I really like molds (that doesn't mean I want you to send me anything out of your refrigerator. Thanks). Here is a mass fruiting of Costantinella terrestris fruiting over soil and mosses in Michigan Hollow State Forest. It's a beautiful thing, red eft notwithstanding. Costantinella is reputed to be the asexual state produced by morels. We'll see. I've never been able to get this one to grow in culture, although it is common around here. I wish I had better luck finding morels. If you're good at that, and you're in the area, you're eligble for my First Morel Contest.
