Hi Ian

Under the dissecting microscope the white gill edges suggested the presence of cheilocystidia. A squash mount of a tiny gill fragment showed what appeared to be cystidia of various shapes – cylindric (but somewhat sinuous) to broadly clavate (with or without a short, narrow apical projection) – but in the squash mount I couldn’t be sure whether they were pleuro or cheilo. Furthermore, I failed to see whole cystidia clearly so I’m only reporting shapes away from cystidial bases. The spores are more -or-less ellipsoid (often with a flattened side); with abundant, fine, low warts over the entire spore surface; they are bright rusty brown in KOH, 6.4-8.0 × 4.0-5.2 mu; no reaction in Melzers. The hyphae are clamped and, both in the gill tissue and in the cap flesh, there are both inflated and uninflated hyphae, diameters ranging from 4 to 16 mu. The cap surface is hyphal. Basidia are narrowly clavate, 20-28 × 5.6-7.2 mu, 4-spored. Your photos show a cortina and I tentatively put this specimen in Gymnopilus. Clearly, my examination was not comprehensive but, given the small amount of material, I am loathe to butcher the collection any further, since I’m fairly ignorant about Gymnopilus-type fungi anyway. I’ll leave it to some expert in the future or an MO commentator.
