That should not have had such an impact.

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.

A puzzle.

Thanks again for the material.

Very best,

Rod

Hmmm it is possible

that they sat on the table in the wax paper a few hours before I got to drying them. Not longer though.

Hello, Geoff.

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.

Very best,

Rod

No sir,

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.

Did you try a drop of KOH on this critter?

The amyloid spores are ellipsoid to elongate to (even) cylindric.

Very best,

Rod
