Compare spore size

With the spores of any other Psathyrella species. P. piluliformis has unusually small spores.

You can borrow a stage micrometer and take a picture of it with your camera, then calculate the number of pixels per micrometer. Then use a program like the gimp to measure how many pixels long and wide the spores are and divide to get a relatively exact measurement. Always zoom either all the way out or in since the zoom on the camera affects the pixels per micrometer.

I cannot measure spores with my scope
