Observation 197623: Mycena (Pers.) Roussel
When: 2015-01-31
(10.3143° -84.825° 1400m)
No herbarium specimen

Notes: I have observed glow in the dark mushrooms for over 20 years at the Monteverde Cloud Forest Biological Preserve where I used to lead Night Hikes. Now I lead night hikes near the preserve at Ficus Trails. I found the mushrooms last year and for the first time we have a large cluster of them. They don’t grow in just any place. The abundance of litter on the ground and the open shady spaces create part of the proper location for them to grow. In the pictures similar mushrooms occur but they are not the same kind ‘cause they do not glow. The disc, the margin, the hymenophore and the pileus all seems to glow but the stipe only seems to glow in some pictures taken at the Monteverde Cloud Forest Preserve so I wonder if they are the same species. As the fruit part decomposes, the bioluminescence fades away but even after several days of being cut off it will continue glowing. There are only two spots in the property where they have been found and they always grow within the same 5 square feet area. There are many insects in the litter and perhaps that’s ideal for them so they grow there. The layer of litter could be from 1/2 to 2 inches thick. The colonies of mushrooms are easily destroy by fallen branches.
Since i am no expert i would appreciate all the help we can get to try to identify these beautiful mushrooms and start learning more about all the other mushrooms we have seen, including the fungus that grows on leaves and sticks.
Thanks a lot.

The picture was taken about 10:45 pm and there was a moon, almost full. That created a problem but after several hours we took various pictures. There were many insects on these mushrooms, specially water bugs, earwigs, some leaf hoppers, mosquitoes, very tiny flies and some slugs. Roaches and mill...

Bioluminescent Fungi at Ficus Trails
Two days after we took 15 pictures, most of the mushrooms were gone and almost half was spread all over the forest floor like if it was a very ripe banana. Nevertheless, Monika Mengel her sister Angelika and their Father came to Ficus Trails and took this wonderful picture.

Mycena tintinabulum

What are the chances of finding Mycena tintinabulum here in the cloud forest of Costa Rica? The pictures uploaded here in MO are very similar to the one picture I took of the bioluminescent mushrooms with light?

We are anxiously waiting for the bioluminescent mushrooms to appear again.

Since the last pictures were taken on February this year the mushrooms have been gone. We have a tripod and we just need to invite friends with good cameras to get the pictures because we don’t have cameras that can take such pictures. We already tried.
We took a picture of the bioluminescent fungus that we have all year round but it only glows when it is wet so we will upload a picture of what we have and soon we hope to get some help from a friend with a good camera.

Thanks so much for your great help.

Gracias Danny Newman

Thank you for taking the time to post your exciting find to MO. As good as it is that you have paid close attention to the fruiting habits of and nearby organisms associated with this fungus, the main thing that will lead us to a species ID is more details of the mushrooms themselves. Try taking a tripod-mounted or steady-handed flash photo of these during the day, or by artificial/indoor light at night. We will need to see, clearly, the base of the stem/attachment to substrate, gills/gill attachment, and pileus surface to be able to say more. Try to include an object with a neutral color value (black, white or grey) in one of the photos to help determine the “true” color of the fruiting bodies.

Also know that even with all this information, there may come a point where only microscopic characters can tell us this Mycena’s name.

Once you can furnish the above information, I can bring this observation to the attention of Dr. Dennis Desjardin, as I am “affiliated” with his lab at San Francisco State University.

As for records of other bioluminescent fungi in Costa Rica, I don’t know of any published ones off the top of my head, but I have personally observed at least one glowing Mycena on the grounds of the La Selva Biological Station. My guess is that there are many bioluminescent species known to occur in your country.

Looking forward to your next update. Let me know if you have any questions.
