I’m done with reticles and slow microscopy

The time is now for transformation from the old to the new.

We should all have a microscope camera. We would be able to swiftly take digital measurements through a software program (with Pixemetre on Microsoft computers).

The old school method is valid and helpful – sometimes necessary – but it’s time consuming and highly discouraging of science.

We need to advance microscopy. It won’t catch on if it’s slow, requires bad posture, or staring into eyepieces. I’m interested in other fields. I can’t sit behind a scope without the right gear accompanying it.

Could you?

Measure everything by hand with a reticle in a eyepiece? That is what I do, takes a little time, but works well. You would have to calibrate it, but that is not hard, if you asked around someone may lend you a stage micrometer which you only need to use once.

You should try it for yourself and see what I see: http://www.orbicule.com/macnification/
You can use it for 30 days – free. Mac only.

The scale bar is accurate. Individual measurements are not displayed ideally, are not automatic and accurate, and you still have to calculate all the other numbers in Excel afterwards. I have asked them to design the program like Pixemetre which is a free Windows app: Click “Téléchargez Piximètre” at http://ach.log.free.fr/Piximetre/ and just walk thru the install in French. It will then work in English and you’ll see the vast improvements.

Looks more like…

Looks more like Galerina, something in sec. Tubariopsis. You can check the cap surface, and if you get a careful look at the spores at 1000x, they don’t have a germ pore, and should be finely punctate without a plage.

I don’t understand what you are saying about measuring spores? Don’t you already have what you need? What is the “20 um” blue block all about? Is that not a measurement of 20um on the image, or is that not a accurate? From that on the image there you should be able to come up with some spore measurements here.

Can everyone see the photo name and/or notes directly below the photos?

The first pic shows cheilocystidia.

Caulocystidia are abundant.

I forked over $200 for Macnification a year ago to do spore measurements and it turns out that they aren’t very interested in making the app mushroom-friendly or fast-paced. I’m going to save a few bucks and get a Chrome Book and install Piximetre on it, unless a better option becomes available. Until that time, consider me limited in microscopy.

First image shows cheilocystidia?

Can you also check the caulocsytidia? Its the first thing to check in the fan6 Conocybe key. And did you work out a spore range and average spore size?

Edit: Looking closer at the actual mushrooms, I wonder if this could be Galerina? Can you check the pileipellis structure?
