Collection location: Strouds Run State Park, Athens, Ohio, USA [Click for map]

No specimen available

The tiny size, viscid cap, and rotting wood habitat are a match for Bolbitius viscosus, but the color is too purple. This mushroom’s cap is about 1 cm in diameter.

I learned a trick many years ago (haven’t practiced it for a long time though):
If you are right-handed, put a blank paper to the right of the object, at the same level. Start staring in the okular with your left eye, keep the right eye open. After a while you can project the object on the paper, and draw the contoure. Divide the drawn size with the magnification, and you have just about the right size ;-)

My microscope did not come with a reticle, just an eye-piece pointer that I have to remove to attach the camera. I don’t know how to make measurements with the set up I have.

- could be f. aleuriatus. It lacks the reticulate cap, is more striate and smaller.
Spores rather thinwalled, 7-12 × 4-5,5 microns.
Did you measure these?
