This mold was found on my carved pumpkin after a week of sitting on my patio. The pumpkin had "melted" and had become soft. Inside of the pumpkin there are several fruit flies and a bit of larvae.

Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species. Traditionally, most of its members were included in the loculoascomycetes, which is not part of the currently accepted classification. This indicates that several traditional morphological features in the class are not unique and DNA sequence comparisons are important to define the class.
