Notes

Note that the specimens in the photograph have unusually large spores - 14x6, 13x7, 15x6, 13x7, 13x6 µm2 - inconsistent with N. episphaeria, although the appearance is identical. According to Gary Samuels, a Nectria/Cosmospora specialist at the United States Department of Agriculture who has examined specimens, they are not N. episphaeria and they are either a yet to be determined known species, or one new to science.
