On Juniperus virginiana. Tiny conchate black, only three or four fruiting bodies. Spores (108) 163-208 x 2.5-3µm. 10 - 31 septate. Asci 165-200 x 9-10µm. It's hard to see, but in the photos in water I think you can see that the spores spiral around each other in the ascus. For some reason the photos in cotton blue don't show that at all.
