[PNW Key Council. Collected by Fred Rhoades and SK.]

Found in Old Growth forest, in duff, together with moss in this case, but we have other collections where it was just conifer duff. Growing in large numbers. It develops iodine odor. It’s smaller than M. filopes that I’m used to seeing. These were never larger than 10 mm, but since the description specifies 5-20 range, we should be fine with the size.

There is a slight problem with cheilocystidia: the stipitate ones, while all shorter than 30 microns (the larger would speak for metata), are the dominant type; I’m not sure if I saw a single sessile one.

There is a larger issue with caulocystidia. They (the clavate ones) should be conspicuous, but it was only with great difficulty that I managed to find a few, all in one place. And I looked carefully on large apex samples from two stipes.

A good thing is that the “silvery lustre imparted on drying out”, characteristic of filopes, is present.

Species Lists


Spores and diverticulate cells on the stipe. Ten spores measured were in hte 7-9 × 3.5-5 range, a bit small for filopes.
A rare visible terminal cell.
Basidia 4-spored, 22+3 x 8.
Cheilocystidia. 23-28 × 13-19, with excrescences 2 microns long.
The unique group of “proper” caulocystidia, found with great difficulty.
