Found by Christine. Broadly ellipsoid spores. On a muddy tire rut. Growing without an apparent mycelial mat. The largest is 1.5 mm in diameter. They sometimes have a faint white marginal zone.
The apothecia are unfortunately immature. It is difficult to find many ejected spores. The spores in ascus are broadly ellipsoid, smooth and small. The few I was able to measure out of the asci were approximately 9-10 x 5-6µm.
The few asci present are IKI-. Paraphyses are enlarged at the tips and contain orange pigments which stain green in IKI.
Dark purplebrown spore drop. Mushrooms look fresh. At base of pine stump and adjacent dead branch.
