We are officially in a moderate drought here so when I found a pair of shriveled specimens fruiting from a very rotted log, they were difficult to ID and promised very little hope of getting any spores from their tightly closed caps. I thought they might be Mycenas, but in order to have any hope of getting to species I decided to see if they would rehydrate. After only 20 minutes in water, they emerged fresh as daisies and even produced a white spore print overnight! Measurements after rehydration: largest cap: 2 cm., lined margin, darker toward center with a prominent bump. Stipe: 3.5 cm., darker toward base which has white mycelium.

Jason taught me that lichen go into “suspended animation/dormancy” during unfavorable conditions and some users have mentioned rehydrating mushrooms, so I decided to give it a try with these specimens. They responded way beyond my expectations:)
I was. I had hoped to open the cap just enough to get a shot of the gills.
Very detailed response, I trust you. Let my original skepticism show just how unbelievable this transformation is!
specimens to begin with. The caps were so shriveled that I could not get a good picture of the gills/gill attachment.
Martin: I’m going to try this more often myself. I’m not sure if other genera respond so dramatically, but what fun it will be to experiment:) The most amazing part of this experiment for me was getting spores from a reconstituted specimen. I guess that speaks to one of the reasons why fungi have been on Earth since the beginning of time.
Jimmie, all scientists should have a healthy dose of skepticism and I am happy to respond to that. I will add two additional photos right after I finish this comment … just for you, since I normally would not post any photos like those to be posted which are out of focus. Image # 1312 shows the split to which you refer. That picture was taken at 5:05:42 P.M., after which I repositioned the specimens (not showing the split) and took a better shot (image # 1314 which was taken at 5:06:25 P.M. Then I picked up the specimens and positioned them between my fingers for a shot of the caps which includes the split cap. That photo was taken at 5:06:48 P.M. After all photos were taken, the collage was created using shots of only the caps. In image # 1313, taken at 5:06:05 P.M., the cap split on the taller specimen is positioned behind the shorter specimen.
If you have additional questions/concerns/doubts, I’ll be glad to try and answer them.
And the spore print is a bonus! I am going to try this sometime!
but I can’t help but be skeptical here.. in photos 3 & 4, where’s the slit in the cap that can be seen in other photos?
