Myriosclerotinia caricis-ampullaceae



Day 235: Updating this: Originally identified from the photos as Myriosclerotinia dennisii by one mycologist, this specimen was referred out by my botany partner Joe to another mycologist who in turn brought in several other experts to study the images. Based on their replies (and they did not necessarily agree with each other), I am amending the identification to Sclerotinia sulcata.

Newer update: this 'shroom has gone 'round the globe! The consensus among the mycological community is that it is in fact Myriosclerotinia caricis-ampullaceae, a rather rare species globally and only recorded in Mount Rainier National Park in 1948. The 1948 specimen is in the University of Illinois herbarium.

Another score by "Team Biota" (Joe and Crow), several dozen were found growing at the edge of a small seasonal pool in the Hudsonsian zone, some with their feet in the water. The height of the tallest was about 5", a 1" cup wobbling on a narrow stipe surrounded by adjacent grass. The others were in various stages of development, and those with larger cups had a tendency to fall over when the support of the grass was removed. The flesh was very thin and brittle, textured with depressions which brought to mind of the hammered metal cookware of the 1950s. Definitely one of the oddest "Freaky Fungi" in Crow's Catalogue, I'm grateful to Joe for tracking down the identity of this unusual 'shroom.
