Hi all, I found this Slime Mould growing on Eurhynchiam striatum (Common Moss) I think! but very unusual as cannot identify, stalkless and growing directly on the tips of the moss leaves. They appear to be like small misshaped discs all <1.0mm, dark blue with globose spores at 10.60 - 11.94 µm with 2.35 capillitium ending with Y-shaped ends hyaline. Spores pale purple grey with just visible spines at around 0.3µm. On large dead trunk of Fagus. Please can you help? First time here, so pleased I found you all.
