One problem for me has been that I don’t like to plug in the dehydrator unless at least a couple of trays are filled. So it has been my practice to air-dry small collections by hanging in the window until there’s a reasonable quantity. Works perfectly well for preserving edibles.

Coincidentally, we converted our house to solar last year. So now, if I use the dehydrator more liberally next season, I won’t care about the electricity :-) I am concerned, though, about my finite supply of 75 watt incandescent bulbs.

New dehydration procedures/priorities will be enforced in the future. At least maybe something was learned about molecular preservation.

If you find this again, please dry it quickly; and we will try to sequence it again if the resources are there for us.

Very best,

A barcode gene sequence was not derived.

A nuclear ribosomal Large Subunit gene was derived, but has some possibly questionable characters in it. It does not match anything deposited in GenBank at the moment. The closest matches are in sect. Lepidella as was expected.

Very best,

Thanks for this one. We have accessioned it.

We can exclude A. chlorinosma because we found immature spores near the stem (best place to look when you can’t find them anywhere else. They were clearly immature and lacked contents. They were faintly amyloid (probably would be darker when mature). The most mature were elongate. There’s no question that this belongs in sect. Lepidella.

Hopefully, we will have more to say later.

Very best,
