[PNW Key Council. Found by Oluna Ceska.]

In Old Growth forest, on needles and moss. Caps 5 mm across, stems 45 mm or less, with white fibrils where attached to the substrate.

Considered M. filopes, which apparently can be this small, but it has conspicuous caulocystidia (absent here). Considered also M. mirata, which is very small, but always 2-spored (or 1-spored). And, perhaps most importantly, the pileipellis observed seems different from both of these species, and any other that I’m seeing in the literature. There seem to be two layers above the hypoderm (inflated cells): one of smooth parallel cells 3.5-7.5 microns thick, and then a layer of diverticulate cells/coralloid mass.

Species Lists


Spores 7-8.5 × 3.5-4.
Caulocystidia 20-26 × 10-14, with excrescences 4.5 × 1, or smaller.
Basidia 4-spored, 21+4 x 6.
Stipitipellis: diverticulate hyphae and terminal cell.
Pileipellis. Diverticulate cells on top, then a layer of smooth parallel cells, then hypoderm.
