Chlorophyllum molybdites, Easten Penn Mushroomers and Nikon microscope

I didn’t know what these were when they sprung up on lawns all over the place around here until Chris Synder of the Eastern Penn Mushroomers described what they were.

The Spore print was done on a glass slide and unfortunately there were not enough spores to see the color. The stain is a Gram’s stain so the color is not native to the spores.

The microscope system belongs to the department where I work and sneak in spore microscopy photos on the side. We just got the scope a few weeks ago and are still learning how to use it. The scope and image capture and measurement software is Nikon. I don’t recall the exact name of the software now – I can find it at work though. The oil immersion lens was on back order but just arrived a few days ago, so my next photos will be at 1000×.

unmistakeable with that habitat, habit and those lovely green gills.

Chlorophyllum molybdites. Gill color looks too dark for other lepiotas, while the ring and cap scales are lepiotalike more than agaricuslike.

What is the bulk spore color? Greenish-grey = Chlorophyllum, dark brown = Agaricus, white = Lepiota (or even Amanita), given the appearance of the mushroom.

I don’t know what you used to mount the spores, but if the pink color indicates that they’re dextrinoid, it points away from Amanita and towards Lepiota and friends.
