The U. of Florida herbarium in Gainesville dates back to the…

Florida Agricultural Station days. The code for the herbarium in Index Herbariorum is FLAS.

Index Herbariorum is now edited by Dr. Barbara Thiers at the New York Botanical Garden (www.nybg.org). You should be able to search for it on that site or directly with Google. One of its features is that from the herbarium code which they now call an acronym you can get information such as address, phone number, staff names, etc. It’s a very useful resource. I sure hope FLAS still exists because that’s where all of Murrill’s types were the last time I borrowed some.

Very best,

even exist? If so, I’d like to see proof.

UF is a public ivy university.

Cool shroom too.

For some reason I can’t use the email function on MO. It says I am not permitted. If you try to contact me via MO email after the holidays, I’d like to hear more about what you collect, how you dry your material, etc.

Very best,

i have a good amount.
i do not keep everything, but as of late i have been trying to keep as much as possible.

Seems to me that your observations often say …

that there’s no herbarium material. When you say you have fungi that need a home do you mean that you have material to deposit in a herbarium?


thank you.

i know all about murrill. i live 2 blocks from where he did.
i hunt almost everyday in the locations he loved most. :-)
have to keep those a secret though…
i hope to be as successful a hunter as him one day.

thanks for the tips on getting better photographs.
i will give them a try.

the head of the mycology dept. at the university of florida retired.
as of now, i do not believe they have replaced him.
it has been very frustrating dealing with them actually.
i have a lot of fungi that needs a home.

You are dead center in the collecting area of W. A. Murrill…

The appendiculate cap margin strong suggests Amanita sect. Lepidella.
I would like to suggest a few things about the photos that would really help in terms of being able to get closer to names for them. It would be helpful if you could suppress both glare and shadow and take your photographs so that the amount of depth of field needed would be reduced.

Here are some suggestions.

1. Make some reflectors out cardboard with aluminum foil wrapped around it. Say three about the size of largish school notebooks. Use masking tape to make hinges so that you have two “covers” on each of the reflector books. With a little pratice in setting the reflectors up and tilting them as necessary, you can eliminate a lot of shadow.

2. To eliminate glare take photographs in shadowed places with open (sunless) sky above. The sky lights the reflectors with a diffuse light. Glare is greatly reduced.

3. Take a few more shots. Lie the mushroom on a nondistracting background (pretty gray is pretty good) so that there is a chance that the cap and the bulb of the stem will both be in focus at the same time. When taking a shot of the underside of the cap get in cloer, forget having the bulb in that shot. Get a shot pretty much straight down on the top of the cap to show warts, marginal striations, etc. If you can’t get the bulb in focus in any other way, shoot the bulb alone. The bulb is terribly important as is the depth to which the stem and bulb penetrate the soil…especially sect. Lepidella. Murrill named a ton of species from Gainesville. There are quite a few that we don’t understand…and the type specimens were badly neglected before a proper herbarium was built (FLAS).

Good luck. I’m hoping to see some surprises from Gainesville.
