Then I don’t know the cause of the apparent downward shift of length distribution and the occasionall appearance of very long spores on the gill surface. The cap looks fairly broadly expanded; so I wouldn’t have expected oversized spores due to an early stage in spore development.
Thanks again for the material.
that they sat on the table in the wax paper a few hours before I got to drying them. Not longer though.
The spores on this material have a distribution of length that suggests that they spent a while waiting to be dried. Is that correct? I’m not sure what their shape would be under “normal” conditions. I’m thinking that the specimen would not have had a positive KOH reaction and might be in the elliptosperma group. We will try to get DNA in coming months. An interesting collection. Thank you.
While I used KOH during my PhD to clear insect specimens, I no longer have a source.
Next year, more measures, KOH and possibly a microscope for spore work. We’ll see.
The amyloid spores are ellipsoid to elongate to (even) cylindric.
