Observation 223349: Psilocybe cyanescens Wakef.

When: 2015-11-16

Collection location: Olympia, Washington, USA [Click for map]

Who: Drew Henderson (Hendre17)

Specimen available

Massive flushes of P. cyanescens in one of our old spots years and years ago that had all but been eaten by the natural mother patch that had resided there for many years. As I was waiting for a lunch meeting this trip the torrential rain and downpour was horrible so I went to this area to park and wait it out. I noticed that where the normal silvery all but stripped of nutrients substrate was actually covered with about two feet of fresh alder chips. The flushes were huge and caespitose lumps weighed about half a pound I estimate.

Huge successive flushes running up into natural briar patches for 50 feet.

Some caps were nearly 8cm wide.

We only collected two specimens for further spore analysis and microscopy.

Readily bluing. Note clusters in the distance with deep bluing reaction from the heavy rain disturbance. Very cold lately and rain hit a month later than usual here. Usually cold can increase bluing reactions with certain species.

Radiant mycelium thatched together feeding on fresh alder is amazing to see up close. So aggressive. Usually it takes a few seasons for fruiting to occur. This dump of alder chips must have occurred at least two seasons ago from my guess.

Elevation: sea level.

Temp: low 40’s. Raining heavily all week.
