Spotting contamination in home mushroom growing
Spotting mould in home mushroom growing
Mushroom Mould Notes explains what the common contaminants look like and how they differ from healthy growth. It also covers where they come from and what growers do to lower the risk.
Made for home growers who want a plain-English reference on mould and contamination.
All the notes
Mould or mycelium? How to tell them apartWhite fuzz on a mushroom substrate can be healthy growth or a contaminant. Here's what extension sources say to look for, and where colour alone misleads.
Common contaminants: green mould, blotch, cobweb and moreWhat the usual mushroom contaminants look like, from green mould and cobweb to bacterial blotch and dry bubble, as described by extension sources.
Why contamination happensWhere mushroom contaminants come from, how spores and bacteria travel, and why wet surfaces and shared equipment raise the risk, with extension sources.
Preventing contamination: clean habits that matterExtension and industry sources on cutting mushroom contamination risk: clean equipment, dry caps, careful watering, fly control and removing dead tissue.
What to do with a contaminated bag, block or tubWhat Penn State Extension and a UK industry body say commercial growers do when mould or bacterial blotch appears, and where that advice stops applying at home.
