Notes: These were found on campus, and brought into class. They are kinda dried out, but I believe they were found that way.
The microscopic images are taken from a gill section, mounted in Meltzer’s reagent (an iodine stain). The first image is at 200x, and shows the gill in cross section (plus a lot of air bubbles…). The basidia of the hymenium can be seen on the left and right, as light yellow cells. The center is the interwoven gill trama, and is reddish from the dextrinoid reaction in the reagent. (Ooh, I get to use such mycology-y terms, look at me go…)
The second image is at 1000x under oil immersion, and the division are 1 micron. This is a close up of the basidia and some spores, still attached.
