and mycelium can have a greenish tinge¹ and look similar to a mold called Trichoderma, which is fatal to them. Advice and discussions go back and forth, often ending with throwing out the batch or burying it in the garden if an infection is suspected.

Bruising is done by notching small cuts along the top and bottom of a mushroom cap and observing any color changes both on the outside and the inside of the mushroom.

What does contaminated mycelium look like?

contamination. As for its appearance on petri dishes, bacterial contamination looks like a slimy, wet patch, hence the nickname “wet spot.” In the photo below, bacterial contamination is identified as the wet looking slime stretching out in finger-like formations from the patch of white mycelium.

What does it mean if a mushroom bruises purple?

What this means is that when a Psilocybe or Panaeolus bruises bluish, the color reaction is a co-indicator that psilocin is or was present. Naturally, since the bluing phenomenon appears to be a parallel decomposition sequence, the more the mushrooms are bruised the less potent they become.”

Can you eat reddening lepiota?

Does mycelium turn blue?

Figure 4: Mycelium-covered grains in the bulk substrate can also bruise blue from the stress caused by pressing against the side of a jar, tub, or bag. Figure 5 from an article on Zamnesia clearly shows the bluish color in a larger area of bruised mycelium.

What is blue bruising?

It often starts red because fresh, oxygen-rich blood has newly pooled underneath the skin. After around 1–2 days, the blood begins to lose oxygen and change color. A bruise that is a few days old will often appear blue, purple, or even black.

How can I tell if mycelium is bad?

Slimy patches on your grain or mycelium signify excess moisture and possible bacterial contamination. You might also notice brown and yellow stains, as well as crusty or gel-like textures.

Can you remove contamination from mycelium?

If it's a small patch but mushrooms are already growing:

If the mould area is only small, smaller than a 50 cent coin for example, the mycelium may contain it itself or you can remove it.

Why is my mycelium turning green?

When this happens it is usually due to a Trichoderma Harzianum infection, although the symptoms are very similar to those of Aspergillus and Penicillium. At first a mycelium-like mould emerges, but when it releases the spores it turns green and spreads really fast throughout the substrate.

Why is mycelium yellow?

? What to do? Mycelium pigmentation and transparent yellow liquid without odors is secondary metabolites (aka mushroom exudate, mushroom urea, mushroom piss). It is a waste product of fungal metabolism or mushroom exudate.

How does Molybdites get rid of Chlorophyllum?

When you see a fairy ring of Chlorophyllum molybdites popping up in your yard, you can immediately remove the fruiting bodies. By removing the mushrooms when they are still immature, you will prevent spores from spreading. However, this will not kill the fungus as a majority of the fungal body is located underground.

Is lepiota poisonous?

Toxicity. Several species contain amatoxins and are lethally poisonous, if consumed.

Is lepiota Felina poisonous?

Does mycelium look fuzzy?

Mycelium can look fuzzy to thread-like or both at the same time. This is a very dense population of mycelium, however, you can hopefully see the water droplets sitting on the mycelium.

Does mycelium need darkness?

The light is not necessary. Mycelium grows well in dark conditions. In commercial growing it is due to the cost cut. The light is mandatory for primordium formation and fruit boddies development.

Can mycelium be different colors?

Its color may vary from white or colorless to brown, black, red, pink, yellow, orange, green, and purple (Conn and Conn, 1941). The substrate mycelia appear to be transparent, slender, phase-dark, and more branched than aerial hyphae under the microscope (Li et al., 2016).

Can mycelium be grey?

White or grayish-white mycelium form on the surface of the rot under humid conditions (A); however, little sporulation occurs at cold-storage temperatures.

What kills Trichoderma?

Yes you can, and Trichoderma often spreads this way.

The best way to prevent this is by disinfecting all of your tools after every use. Either soak them in a 10% bleach and water solution for 30 minutes or wipe them down with rubbing alcohol to kill any mold spores.

What is mushroom blotch?

Brown blotch disease is a bacterial infection that affects nearly every species of mushroom. The infecting bacteria, Pseudomonas tolaasii, produces the toxin tolaasin that causes brown spots to cover the surface of the mushroom.

What does healthy mycelium smell like?

Fresh mycelium smells like cucumber, I would say. For a short moment a light and fresh smell fills your nose as soon as you open a bag of healthy mycelium. Yet as soon as it is out of its plastic skin and build into a tower, the smell starts to mature.

Can bulk substrate get contaminated?

Even with these micro organisms, mycelium will still able to grow on this substrate though. If you sterilize the bulk substrate it becomes as nearly as susceptible to contaminants as highly nutritious spawn substrates like rye berries and brown rice.
