Observation 19016: Boletus chrysenteron Bull.
When: 2009-03-01
No herbarium specimen

Notes: Here is another reason that I need to graduate to a better microscope- my son’s starter kit just ain’t hacking it! So thei mushroom bruised blue instantly. That suggest B. truncatus. The pink in the cracks on the pileus suggests B. chrysenteron But when I look at the spores they don’t seem all that cut short to me. Can someone with some experience tell me?
