Separate intended morphology from unexpected development.
Track green colonies and stalled substrate colonisation.
Keep harvested material protected during drying and storage.
Normal is not always the same across mushrooms
Antler-like growth can be intentional. Brown spore deposits are not automatically a competitor, but unidentified deposits still need examination.
Evidence boundary: Green-mould host records and general process risks are included. No medicinal efficacy or product-safety claim follows from a clean-looking crop.

These links are a differential list, not a claim that your crop has all these diseases. Each entry states whether it is an established host report, a regional study or a generic process/safety risk.
Some mites damage crops or carry contaminants; others feed on mould or other small organisms. Their presence may point to an underlying contamination problem.
A small moving speck is not enough to identify a harmful mite.
Identification can prevent the removal of useful organisms. Biological control still needs the correct pest, product, conditions and local legal status.
A decision guide, not an instruction to release an unapproved organism.
Interpret shape against the intended crop. Air exchange, carbon dioxide, light and crowding interact; a single photograph cannot choose a ventilation setpoint.
Species and strain matter: a shape desired in enoki or king oyster may be undesirable in another crop.
Counting days is not the same as checking readiness. Poor fruiting can follow immature substrate, an unsuitable transition, culture quality or infection.
Species-specific induction and fruiting systems, including cased and uncased crops.
A bag can contain competing mould before green colour is visible. Oyster-associated Trichoderma species differ from the main button-mushroom epidemic species.
Detailed pathogen evidence exists for Pleurotus; the other listed crops have published green-mould host reports, not a shared diagnosis.
Rapidly spreading orange growth is an operational contamination problem. A history of food use for selected Neurospora strains does not make an unknown colony safe.
Generic substrate-contamination differential; not a confirmed disease report for every crop listed.
