[OMS Kelley Point Mycoblitz 2018. A Tullis-Krstic collection.]

Growing on a barkless piece of rotten wood, probably cottonwood.

Keys out to H. argillaceum in both Juelich & Staplers and Bernicchia & Gorjon monographs. The only discrepancy with the description is the width of generative hyphae. The spec says about three microns and I’m finding 5-6 microns in those several places where I could actually see the hyphae.

Species Lists


Long projecting cystidia seen as yellow dots. This was a rather dry collection.
Basiidia 18-24 × 6.5-7.5, clamped. Spores 8.5-9-4.5, inamyloid.
Cystidia up to 200 × 13.
Cystidium in KOH.
Some rather thick (6 microns) broken hyphae at bottom center.
Basidia and cystidia were often collapsed, not only in KOH.
