This was the first one I cut. Pleurotus ostreatus
Next, Psilocybe caerulescens var. weilii pleurocystidia. I am going to rehydrate and try and section a piece of a more "var. caerulescens" fruit. We'll see if there are pleurocystidia as well. I say hell yes.

Have you mounted them in anything or are you looking at them dry? If it's the latter try putting a drop of water on your section and then a cover slip over the top.

Yes I have them on slides. The oyster, I thinly sliced a piece of one gill, so its like a gill cut down the middle kind of on an angle. I "fileted" it. The caerulescens was really difficult because I had to rehydrate the piece of dried cap. I've made a few conclusions... Fresh material is better than dried, and LBM's are fucking difficult as shit to slice thinly. I give mad props to all you guys busting your balls scoping tiny little LBM's. Its hard, but so much fun! Its like another world within this hobby.

Welcome to the club man! I'm still not very good at using this thing even though I got it a year ago. Practice makes permanent, so keep it up. I'm happy for you, merry Christmas  I just got a stage micrometer for Christmas this year, so I'll actually can measure the things that I see.

Nice, I have one too, you can't actually measure anything with it, you only use it to calibrate a reticle that is fitted into one of the eyepieces!

You need a reticle which is fitted into one of the eyepieces, the reticle needs to be calibrated using a stage micrometer.

The best way is to use a camera to take a photo of a stage micrometer, and then use that photo to calibrate software like Piximetre. Then you can measure lots of spores quickly and it automatically calculates spore statistics and stuff.
You can also use a reticle, but that costs money and is a lot slower.

I used a similar method to create scales to overlay onto my micrographs using Gimp. Some examples here. http://mushroomobserver.org/55302?q=1huQD http://mushroomobserver.org/50379?q=1huQi
I see no problems with your method Alan as long as it is a properly mounted camera, if one is lining a camera up to one of the eyepieces or using any other unconventional or makeshift method whereby it's possible that every time the camera is set up it is not exactly as it was when the calibration photo was taken the measurements made with your software will be out and because we are talking increments often as small as 1µm the slightest difference in how the camera is mounted could affect your measurements drastically.

So yes because I am shooting down the lens with my camera manually, should I just go with the stage micrometer and reticle? Sounds like this is the more time-consuming, yet sure-fire way to get an accurate measurement.

Its not that much slower, you can measure ~20 spores in 10-15 minutes. The time intensive part is doing all the math.

You might consider getting a USB microscope camera and never adjust its position once you install it properly.
If you do adjust it, just go thru the recalibration process again. You should do that every now 'n' then to be sure, regardless.

Have any of you ever tried comparing measurements made by hand to those made by the program? I would think that often you will need to adjust the focus by hand to see the entire cell and measure it accurately. This is especially true with cystidia.

I have compared, briefly, manual measurements with another program (Macnification), and the manual software measurements I took were very close to the reticle measurements.
When you look through a reticle for the measurements, there is still a bit of mental judgment used to determine the amount of microns to the .5 or to the 1/10th micron. It's more precise if calibration and slide preparation are performed perfectly and software is used.

Measurements don't need to be that accurate, off by .5 would still give you the same results. Remember you're comparing with people who did all the measurements by hand using these same mental judgments. 
These were spores you compared? How big were they? How about cystidia? Smaller spores often appear in their entirety without changing the focus.

I can't recall but I believe I compared both cystidia and spores, and I'm unsure of the measurement sizes.
Super thin sections (and super thin spore slides with a very small amount of water) should improve the plain-level of sight and reduce the need for constantly re-focusing.

As long as the camera lens is always the same distance from the eyepiece, I think you should measure digitally. Also helps to use the manual focus set at the same distance, as the focus can change the scale a bit. I usually set manual focus to about a meter.

Also pressing down firmly on the cover slip with some lens paper or paper towel helps force all the cells into the same focal plane.

no, if you make a 'jig' to hold your camera up to the eyepiece, so long as you can make it consistent each time you place the camera, you can use piximeter to do the actual measurements after you get your stage micrometer.
1) get piximeter installed 2) get stage micrometer 3) get comfortable shooting down the barrel of the scope 4) take pictures of the stage micrometer with each of the lenses 5) use the pictures from 4. to calibrate piximeter 6) prepare slides, take photos using same method as 4 7) use piximeter to tell you how big the object you photo'd is.
i just went through it recently so the process is fresh.
a reticule is not necessary unless you don't have a computer and a camera, in which case, i'm pretty sure it is. they're only thirty bucks, while a camera and a computer could run you a bit more.  a usb cam would no doubt make everything much more accurate, probably more precise, and easier. Its a pain in the ass trying to get a cam phone to line up from my experience.

Alan is always saying one can use blood cells instead of a micrometer. They are on average 8 nanometers. I think.
Maynard, you could probably get a micrometer at the library as OSU. Or even borrow one from a lab for a bit.

1) get piximeter installed 2) get stage micrometer 3) get comfortable shooting down the barrel of the scope 4) take pictures of the stage micrometer with each of the lenses 5) use the pictures from 4. to calibrate piximeter 6) prepare slides, take photos using same method as 4 7) use piximeter to tell you how big the object you photo'd is.
i just went through it recently so the process is fresh.
a reticule is not necessary unless you don't have a computer and a camera, in which case, i'm pretty sure it is. they're only thirty bucks, while a camera and a computer could run you a bit more.  a usb cam would no doubt make everything much more accurate, probably more precise, and easier. Its a pain in the ass trying to get a cam phone to line up from my experience.
congratulations hashfinger! may your coverslips never crack
 Maynard has a usb cam, do you (hashfinger) need one?
I have a Nikon digital camera. I think if I do like someone said and make a fixture/mounting device so the camera is always the same distance, I'll get away with murder. First things first I need to order a stage micrometer and download some software. You tell me... Do I need a usb cam?

RuralAnomaly said: no, if you make a 'jig' to hold your camera up to the eyepiece, so long as you can make it consistent each time you place the camera, you can use piximeter to do the actual measurements after you get your stage micrometer.

nope not if you are using a cmaera, get a microscope adapter for your body if you can.
