Collection location: Boston, Massachusetts, USA [Click for map]
I found this in wood chips in my back yard in Allston and was stumped. I took it to Don Pfister at the Farlow Herbarium and he ID’d it as Acervus epispartius. Apparently, this may be the only collection of this fungus in Massachusetts!
It was a real stumper! I had trouble because I just couldn’t figure out if it was operculate or not because I did see one true operculum but didn’t see it anywhere else in the hour or so I spent looking at this thing. What I was seeing didn’t match anything in Seaver, Fungi of Switzerland, Dennis, etc… but it is in Bessette.
The apothecia are about 2cm at the largest, bright orange with a felty, whitish underside. Astipitate. Young ascocarps have a flap that covers the hymenium, and as the body opens, the flap ruptures but clings on for a little while before falling off. If you look hard you can see the little flap still clinging on to the margin of the mature fruiting body. That’s a good macro-characteristic for this fungus.
Also, under Don’s and Kathy LoBuglio’s supervision at the Farlow, we tried to culture the spores and tissue with no success. Don tried a heat and cold shock treatment on some plates but no luck.
