Panaeolus cyanescens - Black Spots on Fruit Bodies
    #18824480 - 09/10/13 05:50 PM (10 years, 5 months ago)

Hi everyone!

This is my first post in this beautiful message board, and I was reading silently for a long time before this first post. I have cultivated cubensis for quite a while, as well as Panaeolus cyanescens "Jamaica".

Now I ran into a problem with the emerging fruit bodies. After rapid growth to almost maturity, the fruit bodies stopped growing, and I found some black spots on the stems of the fruit bodies. The black spots just appeared during one day.

This is what the shrooms looked like yesterday:


Today they looked like this:


This is how the black spots look like on the shroom:


The substrate was birdseed that was bulked into sterilized Timothy hay with cow manure. The cover layer was pure vermiculite, poured over with boiling water and applied over the substrate after it was cooled down.

My question is the following:
Are these black spots a disease or are the fruit bodies aborting for some reason?

Thank you so much for your help!

Looks like bruising to me. Did you touch them? Mist them?

Looks like direct misting to me.

OP....mist upwards so that only a fine mist blows around.  Spraying the pins directly can abort them.

Thank you guys for your quick reply!

I knew (from this message board) that emerging fruit bodies should not be misted, so I didn't do that. But I might have been to eager to make nice pictures, so I have hit a couple of the fruit bodies with my camera by accident. But I never expected them to abort that rapidly.

I harvested most of the fruit bodies to prevent further aborting, but I left a couple of the healthy looking ones standing. I will report here what happens to them. I hope they get to maturity so I can produce some nice prints for the FSRE.

Thanks a lot, everyone!

Hi everyone,
your advice was correct. It must have been bruising, rather than any type of infection. After I saw the black spots on some of the fruit bodies, I harvested all except for a group of fruit bodies (standing on the far right side). Since then I haven't touched or misted them, and new fruit bodies have come up and they all look healthy. Here are some pictures from the last couple of days. One picture was taken per day, the last picture is from today. Have fun :laugh:
