Dryness

It’s also important to realize from the beginning the effort necessary to keep insects OUT of the herbarium. And to keep the herbarium as dry as possible. MOLD is a great enemy. Molds will selectively eat spores and the tops of basidia to get at the concentrations of protein and vitamins. Then what can you do with the material as far as anatomy is concerned? Not bloody much.

I have been in herbaria where warm wet winds came through open windows seasonally. Even recently collected material was unusable for distinguishing anything. Even tissues preserved well by quick drying are useless and impossible to rehydrate after the cell walls are broken by invasive molds.

DRYNESS. INSECT DISCOURAGEMENT.

Big numbers. Freezing well-dried specimens kills insect eggs (very good). Freezing imperfectly dried specimens can break cell walls (very bad).

DRYNESS. INSECT DISCOURAGEMENT.

A herbarium mantra.

The other mantra is labeling and organization.

Once you put it in. You want to be able to easily find it and take it out to work on or to loan or to send a piece to somebody else.

Very best,

Rod

I’m excited

that other people are motivated to keep personal herbaria documented properly. This is how amateur mycology advances!

Way to go Tim.

You’re welcome

If I am going to bother keeping a personal herbarium, I better be doing it right!

Thanks again, Rod. I appreciate all your hard work immensely.

No problem

You learned something. Hence, my time was spent properly.

Very best,

and no date is written on my specimen. I know that the specimen came from the same patch as the photos, within a a week or two of them, but I am not certain of the exact date.

This patch is close to my home, and I plan on collecting a properly documented specimen for you in the future.

Thanks for your time, and sorry for the confusion.

Sorry, not sure I understand.

Let me see if I understand.

These images were taken at the Shorecrest H.S. site 7.iii.2010.

Do you have dried material and a spore print from the same place on the same date as us represented by these photos? Or is the dried material and spore print from the same place, but collected on a different date?

I need a collection of material (including at least some that was mature and producing spores when it was dried) and photographic or written documentation of the very same collection (same site and same date).

Collections from the spring and the fall could be the same species; however, on the west coast, there is good evidence that some species fruit MOSTLY or ENTIRELY only in one part of the “rainy season” (restricted to early season or restricted to late season). Hence, the need for precise linkage of image(s) and collection.

There is no harm in sending more than one collection form a site from different times of year. It’s just that without a detailed description and/or a photograph it may take a taxonomist almost as long to identify a familiar species as to identify an utterly new one…and for a guy just beyond the middle of his sixtes, I need the most efficient option. :-)

There are literally thousands of amanitas (pretty much sorted and cataloged…but far from all identified and very, very far from all written up and published) all around your humble servant. :-)

Very best,

Rod

I have a specimen and spore

print from this collection, but I have no proof or record that the mushroom matches the photo. If you are still interested I can send it to you. Thanks for all the help, Rod!

OK

Tim,

If you have material from this collection in which the cap was fully opened, then we might have spores; and I would be interested in seeing the collection.

Sincerely,

Rod Tulloss
