Mostly, I have my equipment to thank. In turn, I have my professor and the University to thank.
The only other methodology I use that might make a difference is that I often make sections vertically from a SINGLE gill laying face-side down – not from a “wedge” of cap and gill tissue as some suggest. Also, I make sections using a very powerful dissecting scope (also from Nikon), and use the thinnest available cover glass.
I have a picture of the nice Nikon scope he uses here. This picture also includes a pic of the key to the lab but I reduced the resolution enough that the key can not be duplicated from the image. I am also curious how this image was made, the gill face looks so clean and visible, almost like it was made with something more like a stereo zoom microscope. Sometimes I can see cool stuff like this when I look at a gill face but usually it looks more like a blurry mass of cells.
Very high resolution and very clean photo 36923. Please share the
equipment and technique.
With this high resolution you can give us some more
Amongst other things, the spores really look like something in the
emetica Section — silvicola/cremoricolor, in our area…
I’m not sure exactly what you are asking, but it is a lamellar fragment mounted in Melzer’s.
As for Mike Davis, I heard him speak at the FFSC meeting – I find that the “Russula Gallery” is a great first step, but currently of limited utility. The main usability problem is the poor choice of page-by-page formatting. Even working around this, there is a problem with inconsistent reporting of characteristics. Some entries say SV-, some say SV+, and some do not report SV reaction at all, etc…
