Images

a basidium with 3 of six sterigmata showing
a cluster of 6 phloxine-stained spores (4 are visible) that are still probably attached to the basidium, but the latter is completely invisible. This was very common to see. In fact it was very hard to find a basidium that was mature.
a close-up of this rather uninspiring resupinate.
clamps on hyphae were common and obvious
