Didn’t look immature to me

I have to constrain myself only to study well-developed specimens or I wouldn’t get anywhere on these hikes! These seemed to pass the test, since there were so many, some clearly immature, others older and thus presumably not (they had time to dry out, for example). I’ve just been looking at the gills with a hand-lens in as bright light as I can manage. Generally, brown (even ochre) spores show up clearly against pale gills this way. Now pink, yellowish, creamy?… I couldn’t say.

You don’t think that perhaps the section you viewed under the microscope might have been immature, thus the spores were either not formed or not pigmented yet?
