Observation 29681: Galerina marginata (Batsch) Kühner
When: 2009-12-06
No herbarium specimen

Notes: Found this in large Numbers growing on a very old decaying tulip tree poplar. The stems bruise blue but then turns a violet then black over 30 min. The caps are large to small about 7 cm to 3 cm across. Older mature ones have upturned gills and develop a dark line around the margin in age. . Spore print pic on the way. I have tentatively put his into the Psilocybe genus because of the bluing reaction but it very well may be a Pholiota or Galerina group.

Kind of figured it was Galerina

What was confusing was the bluing like reaction upon crushing the stems I think it has to do with the fact everything out side is White so it make things look a bit different. In the light at my house it is clearly black, the staining reaction. What I thought was a bit different with this is the way the gills are. They seem very crowded and others of the Galerina group, I have found the gills seem a bit more spaced. they are also very large compared to others I have found which have had caps no bigger than a quarter. Pic 68249 is the same as pic # 68250. There must be several different species of Galerina that inhabit wood. I have found Many that look very different than these. In Observation 29598 i have classified as a Galerina but the gills are very Red like a Dermacybe Cortinarius. The Habitat though is that of the Galerina.

Um, staining?

Galerina marginata doesn’t stain when handling. Or stain blue, or develop any blue colors. But the gills here in age are too brown to light brown to be Psilocybe.

On the other hand, the wood rotting Galerinas all turn very deep brown (like coffee) from the base upward in age. In the case of Galerina marginata the stipe can be veyr light colored, pallid to light tan when young, and become much darker in age. Even though it is become dark, it retains a covering of white thin hyphae. This hyphae can rub off very easily, so it can look like you are getting a dark bruise, but it is thin hyphae coming off.

Although I can’t help you with the blue… These do look rather old and dried out for a Galerina, so who knows what might happen by then…

deadly, not Psilocybe

If you were some sort of hippie, you could be dead now. Its scary that 18 people viewed this observation and no one said anything about it yet.
