Observation 4111: Russula aeruginea Fr.

When: 2007-09-08

Collection location: Diamond and Crater Lake, Oregon, USA [Click for map]

Who: Douglas Smith (douglas)

No specimen available

Notes:
There were a few of these up there, and they were striking with the green, slightly blue-green color of the caps. As you can see from the older one, the spore color is yellow, and the caps lose some greeenish color, to develop yellow tones in the disk. The taste of these is mild.

I put a bit of gill under the scope, and was able to look at the spores, they were amyloid and warted (or course). But the warts were small, and laking ridges between the warts (not reticulated). I still don’t know how to measure spore size, much less wart size. But I was pointed to a new Russula monograph from Vancouver Island studies (was done at Univ. Victoria maybe?). This has a chart of how spores should look, which was useful, and I was able to compare how the spore look to the chart to get a rough idea of wart size.

From this, and the color, taste, and spore color, this point to the id of R. aeruginea.
