Observation 107457: Hypholoma fasciculare (Huds.) P. Kumm.

When: 2012-08-28

Collection location: Rock Creek Regional Park, Montgomery Co., Maryland, USA [Click for map]

Who: Martin Livezey (MLivezey)

No specimen available

On our nightly dog walk, we shone my new UV flashlight into the forest duff. Except for a few bits of trash, we did not see much, until these bright green mushrooms appeared about 20’ off the trail. Photos by digital camera with white balance on appear slightly illuminated, but trust me, these were glowing in the dark! Normal exposure with and without flash.

ok guys, thanks for the quick response :)
maybe the ‘bioluminescence-part’ of the website should be updated :)

just UV fluorescence

I have never heard of actual bioluminescence in Hypholoma

bioluminescence in Hypholoma fasciculare

Hi Martin,

Since I found this in the bioluminescence gallery of this site,
I was wondering if they are actually glowing, or just showing response on a UV torch?
A quick google & google scholar search didn’t bring up cases of bioluminescence in Hypholoma fasciculare
I just sat down in my cellar with a bunch of these (or I suppose it was H. Fasciculare , not an expert myself), in Europe. Didn’t notice anything, though :) Might post photos later.

Hope to hear again from this observation
