Emerging from large decaying hardwood log in the bottom of low moist woodland draw dominated by paw paw trees. Locally abundant on log and absent on nearby logs. Specimens appear to be parasitizing Ophiocordyceps variabilis and/or directly competing for its larval host.

In flowerbed with irises, but near a very large pin oak. Smells mildly cheesy-nutty-mushroomy.

Spores were photographed under a microscope by Chance Brueggeman (cbrueg). He observed mainly 4 spores per asci, some less, and very few with 5. He observed it was dextrinoid in Melzer's Reagent.

Growing gregariously on large well-rotted Eastern Cottonwood log in low, moist riparian woodland area near small creek.

Pileipellis and stipe navy blue to nearly black. Gills turning pink with age. Quite small. Spores angular.

Found in ravine at 1200ft elevation, no rain for a couple days, 80° high but it was relatively cooler in the pit of this valley. Water still running. Probably 15-20ft up the hill from the running water. Host: Cicada nymph? Ophiocordyceps heterpoda sensu lato(?)

This felt more like a mushroom than that orange foam stuff. I believe the holes are from where little kids poked a stick through it. I don't know what species of tree this was, but I do know it was deciduous.
