Hi Dave-I have seen some interesting species in the samples so far. Among them, Terpsinoe sp. which I've not previously encountered. I think with some of the literature you have I may be able to make some progress with identification this summer on the West Texas sample set. I can do some photography at the Confocal Lab at New Mexico State University.I'm interested in any diatom resources that you will be getting rid of once you make your decision. I plan on continuing diatom work here in the Southwest.I'm attaching a photo I took of the Terpsinoe from one of the recent samples.-Andy

Dick, et al.
As I have not heard from you or anybody else in regard to my
(unfortunately) double message (the forst one was not posted by Yahoo
for hours and then showed up AFTER I reposted) I'm not sure that
anybody got it.
To sum up - Andy Potter should have the slides ready soon. Are you
still willing to look at them? I have contacted the California
Academy of Sciences and they will take the left-over material.
Unfortunately the Lake Lucero sample had nothing in it, but I think
the rest may well be interesting. There should be at least ten or so
slides, mostly from West Texas.
As I said in my delayed message, I may have to make a hard decision
soon. With Mac gone and my options somewhat limited by circumstances I
may be throwing in the towel. I've enjoyed this very much and my
associations with various diatomists has been very fruitful. However
I am getting very little done lately in this and I would rather the
library and equipment be used than sit around.

Your note adds a lot to this great discussion of amateur study of diatoms. I have had your experience of using the SEM images to explain what I see with the LM. Dick has been one of my main sources for learning, too.
I see this discussion as what to do about distinguishing species, if that is possible for anyone, even with an SEM and a molecular lab. Even Dick, with the university library in Phoenix, is challenged, as he says. From my seat, the naming discussions have been cordial so far, e.g., Charles asking Dick to clarify a name as far as possible and Dick replying with a careful answer.
I certainly share the frustration I think I hear from Dick about pinning down an identification. I am finding that taking on any of this demands an acceptance of just not being able to know. Your point about not caring about naming accuracy may be the way to go here.
Hearing from you, Dick, and Dave helps me try to figure out what direction I want to take with all the images that I am accumulating and what it is I want to learn. Do I want to make species (or genus) lists of collections made? Am I happy with naming to genus? Do I want to learn more ecology? How important is sharing what I learn? (This forum has been a good place for that so far.) Do I want to continue developing LM technique?
By the way, would you be willing to ID some extant Mastogloia from the California desert?

Due to a catastrophic meltdown of my hard drive on my laptop I have been kept out of the loop for some time, only to find that where evryone behaved and everyone gained something from the group I now find there are ripples of dissent] and over what NAMES!
May I remind you all that when I first joined the group I quoted my dear friend Bernard Hartley who on our first meeting said " We must/ should never fall out over a name". Now I find that there is dissent over naming of Diatoms, those of you old enough and studied Diatoms before the advent of TEM, SEM will remember the advocates of doom and gloom saying these would be the death of amateurs. As it turned out it was far from the truth with the instruments often showing details which had been seen by amateurs and in fact the reverse was also true we often went back to our slides after seeing an SEM photo and lo and behold we now see what has been missed before.
This brings me to my main point, do not throw your dummies out of the pram over such an issue as names of Diatoms, I was very intimidated by the naming of Diatoms until I joined this group and Charles has been instrumental in my starting to enjoy this, true my main reason for avoiding that was lack of literature and with each of Charles's posting I learned a little more.
Charles if you are serious about throwing in the towel would you consider exchanging emails with me and continue your excellent teachings? I would be honoured and do not give a damn about if you are up to date within the last hour.
FOR THOSE WHO THINK WE ARE OUT OF DATE "WHAT ARE YOU DOING HERE"?
