In the "little black dots on wood" category is Cercophora scortea. Apparently this is only the second reported collection of this species in the United States; the first one being found in Louisiana by Gary Samuels. It was originally described from Canada and is also known in Europe. This specimen was cultured and studied by Andrew Miller and Sabine Huhndorf of The Field Museum as part of their investigation on the systematics of the Lasiosphaeriaceae. While carefully examining the various chunks of wood and branches on the identification tables, Andy found the Cercophora on wood with the jelly fungus Calocera cornea (voucher 1999-109).
