On a well-weathered wooden fence post. Photo 2 shows several spores in a potassium hydroxide (KOH) solution. The size range of the 25 measured spores was 21.6-28.0 x 8.8-12.4 microns. Photo 3 shows the entire sample collected for the herbarium. On the left side of Photo 4 you see a broken fruit body (on a slide in a drop of KOH and after the cover slip has been pressed a bit). On being placed in KOH the fruit body immediately exuded a reddish-crimson pigment, which looks more reddish-brown as it diffuses further into the KOH. On the right is a view, through a microscope, of part of that broken fruit body. Much of that view shows red pigment, but the upper and lower right are still colourless, the pigment not yet having been able to diffuse into those areas.
