Observation 25582: Omphalotus illudens (Schwein.) Bresinsky & Besl

When: 2009-09-22

Collection location: York Haven, Pennsylvania, USA [Click for map]

No specimen available

These bright orange mushrooms were found growing in multiple clusters on a decaying oak tree stump. The sample mushroom I collected for a cross section revealed an orange colored solid cored stipe with the exception of holes bored into the stipe by insects. The mushrooms in these clusters are on an average length of 15 cm with the caps on average of 5 cm wide. I brushed the cap with ammonia which stained an olive green color. The aroma is that of a button mushroom you would buy from a grocery store. Weather note, today it rained with the temps in the mid 70’s. I have passed this stump several times in the last two weeks, this is the first time I have observed these mushrooms growing on this stump.

Do the spores play a role in the illumination ie glow ?

That is truly awesome the way they glow. What type of camera did you use to capture the image of the glowing mushrooms? It appears as if you focused on the gills to obtain the glowing image. I will see if the mushrooms I observed will glow. If they do I will try to capture it digitaly. Thanks so much for the comment. Kate

do glow, (but not all) I found a few big clusters last week that had a faint glow.
Here’s some I found a couple of years ago in West Virgina that had a bright glow.

I am tempted to take a drive with baloney sandwich in hand to see if they do glow green.

I must have looked at 20 different pictures of these mushrooms when I was determing if the Chantrelles I found were in fact Chantrelles. I knew as soon as I saw them what they were from all the eye strain I had researching Chantrelles. Interestingly these mushrooms are a mere mile away from the Chantrelles on the same dirt road on the same north facing side in Etters. They are lovely to observe however I will stick to plane baloney sans the mushrooms!

There very beautiful but very toxic. so Don’t eat them. They contain muscarine which ingested will mess your week up and i miss Quoted David Arora. Its a grilled cheese sandwich not baloney

Ok now pick some of them make a baloney sandwich and go into a dark closet and see if the gills start to glow. According to David Arora it happens quicker if you eating a baloney sandwich. These guys are suppose to glow in the dark
