At the corresponding observation suggests these are Coryne dubia, an anamorphic Ascocoryne, which would make those extremely small spores conidia, and help explain the purple coloration.

everything was difficult to see clearly in this mount. I am assuming that the long, filliform formations are tuning-fork basidia of the Dacrymycetaceae type, an the tiny, two-oil-droplet-having, elongate-cylindrical, sometimes bean-shaped things are spores. the last micrograph shows what I hope are two spores at the ends of two sterigmata.

if this is D. spathularia, it is unusual to see it so purple upon drying. every example I have seen before these has not dried this color. this was the principal feature that drew my attention to this fungus in the first place.
