Observation 118906: Atheniella leptophylla (Peck) Gminder & Böhning

Growing on a dead tree (oak?), about 1 m from the ground, in the same area of the forest where I found M. leptophylla last year (Observation 83451).

Odor spermatic; was easy to detect it when cutting a small piece (2 × 3 mm) from the cap.

Spores 6.5-8.5 × 5-6 microns. Basidia 4-spored. Cheilocystidia forming a band. Couldn’t get a whole cystidium in reasonably good shape out to see what its bottom looks like; apparently their lower parts are not much fatter and the size is about 35 × 5 microns.

The mushroom belong to the Adonidae section, the status of which, according to Maas G is “anything but firmly established”. (Don’t know if things have significantly changed since 1992.) Pretty good match with the description of M. leptophylla, esp. if one does not insist on subglobose spores (Maas G doesn’t).
