Thanks, Penny and Dave.

Pluteus fits. Unfortunately I didn’t collect the cap, so no spore print to help with ID. I found this very similar observation from my area: http://mushroomobserver.org/86809.

I made my first spore print for another observation: http://mushroomobserver.org/209082. I used glass from a picture frame and made the print overnight in my (air-conditioned) office.

Thanks again!

Sarah, if you have an unused piece of glass

like from an old picture frame, you can put the cap (gills down) on that overnight and in the morning put the glass with print onto white and black paper for the photo. Use natural light if possible to get the most accurate color. I don’t have air conditioning so it is quite humid here in VA, and I always cover my printing mushrooms with a cup or bowl. The glass will need to be washed with soap and water as some spore prints are kind of grippy. I use a soapy paper towel, then stand the glass in an out of the way area to dry. Have fun! Penny

That’s a good question, Sarah.

I’m not sure how to work around the humidity. I suspect that the mushroom may not drop any spores if it’s too cold. And, I’m not sure how your refrigerator works, but if warm humid air is cooled, then the relative humidity increases. I suppose fridges are built to dehumidify.

Try half a cap outside the fridge, and half inside.

Thanks, Dave!

Gainesville is swampy, and I keep my apartment around 82°F in the summer. Should I make spore prints in the fridge? Seems like the cap might get nasty after 20 hours on the counter.

To make a spore print…

Just lie the cap, gills down, onto preferably non-porous surfaces that alternate black/white. If the mushroom is placed in an area where air circulates readily, or people moving cause currents, then cover with a cup. Good thick spore print generally takes 10-20 hours to collect. Immature or overly mature specimens may fail to produce a print.

Honestly, I’ve yet to make a spore print. That’s probably the next thing I should learn.

Have you observed a spore print color? This looks a bit like a Pluteus to me.
