These photos show various fruit bodies in one herbarium collection. The specimens were dried after collection. However, the fruit bodies have a low water content and so look much like this out in the wild (particularly in dry conditions). Photo 1 shows fruit bodies with the epiphragms still intact. The white rectangle in Photo 2 marks what you saw in Photo 1. The white arrows point to two fruit bodies in which the epiphragms have broken and so left the mouths of the fruit bodies open. At the upper right are four spores (naturally colourless but two I have stained red). On the left in Photo 3 you see one fruit body cut in half (with a large lump of substrate still attached at the bottom). In the peridiole-free upper area you can see the smoothness of the fruit body’s inner wall. The arrow points to the connection between one peridiole and the inner wall. On the right I show all the peridioles that were in one fruit body. The rightmost five have white funiculi. All the other peridioles lack funiculi and were I to turn them over you’d again see smooth, black surfaces.
