White fuzz on mushrooms – Safe to Eat? Growing Advice?


Two types of people are looking at this article, people who have white fuzz on mushrooms they are about to eat, and people who are growing mushrooms which are developing white fuzz on their stems.

This article is for both types of people so that they can figure out what the fuzz on their mushrooms are, and what to do about them.

What Is The White Fuzz On Mushrooms?

The white fuzz on mushrooms is called mycelium. It is a mass of thread-like filaments that make up the body of a mushroom.

The mycelium helps the mushroom absorb nutrients from the soil and also helps protect it from predators.

Mushrooms are the “fruits” of huge mycelium networks so, as you look and say “what is all this white fuzz coming off my mushroom” the mushroom was actually produced by those tiny white strands.

Actually, you are about to eat the white fuzz's reproductive system.

Hopefully that little fact hasn't put you off your dinner!

Is The White Fuzz On Mushrooms Edible?

Don't worry the white fuzz (mycelium) is perfectly edible and won't cause you any issue.

In fact for some mushrooms such as the lion's mane mushroom the mycelium is actually considered to be the most valuable tissue.

So next time you see some white fuzz on your mushrooms just know it's the mycelium and it's totally normal. 

Ensure the white fuzz is coming from the mushroom and isn't a mold colonizing on top of it, see the picture above for an example.

White Fuzz On Mushrooms Whilst Growing or Cultivating?

Totally normal, finding fuzz (mycelium) on the stem of the mushroom is totally normal and nothing to worry about. 

Basically the fruit has developed extra mycelium to absorb some humidity and fresh air from its environment,this will in no way affect your growth.

In fact, the top half of this article is directed at people who have found this phenomenon on their mushrooms farmed by professionals and sold at supermarkets.

Alongside this, the featured image contains a mushroom found in the wild growing a white fuzz coming off it, so don't worry about it!
