I returned to the site where I found these in 2009 a little more prepared. The ascomata in the first image I think were on the same log as the 2009 observation. The ascomata in the rest of the images were on a log about 20-25 feet away and across the trail. Over two days I also found smaller collections of these in two other locations up to a mile or two away. In all cases the substrate was a downed, partially rotted hackberry log (Celtis occidentalis). The others were found by searching for that substrate.
