Quick orientation
Keep intact logs and formulated hardwood sawdust as separate substrate records with supply and quality evidence. This topic keeps Lentinula edodes log and sterile sawdust-block methods separate, including their different incubation and maturation responsibilities.
Why this stage matters
Keep intact logs and formulated hardwood sawdust as separate substrate records with supply and quality evidence.
Method boundary
This topic keeps Lentinula edodes log and sterile sawdust-block methods separate, including their different incubation and maturation responsibilities.
- Confirm the culture as Lentinula edodes, with strain or variety recorded where available.
- Confirm one method: natural log or sterilized sawdust block.
- Record substrate source, treatment class, batch and contamination observations.
Observe and record
Use batch records, stage dates, room observations and contamination patterns. Compare the crop with its own prior condition before changing several variables at once.
Evidence status
The page publishes process relationships supported by primary institutional sources. Numeric recipes remain absent where source context, strain identity or specialist review is incomplete.
Reusable residue records
A substrate name is only the first question.
RES-PADDY-STRAWPaddy straw
Treatment changes by species and method; a shared residue name does not create a shared process.
Evidence-linked species
- Oyster mushroom group: treated straw bag methods
- Milky mushroom: treated straw plus casing methods
- Paddy straw mushroom: bed and validated container methods
Quality checks
source and crop history; dry storage; visible contamination; chemical-residue risk; age and weathering; physical form
RES-WHEAT-STRAWWheat straw
No automatic recommendation for every strain, supplement or treatment system.
Evidence-linked species
- Oyster mushroom group: documented straw bag category
- Milky mushroom: documented straw substrate category
Quality checks
source; storage moisture; mould; residue exposure; particle structure
RES-HARDWOODHardwood log or sawdust
Tree species, log and sawdust methods, and supplementation cannot be collapsed into one input.
Evidence-linked species
- Shiitake: log and formulated-block evidence are separate
- Lion's mane: wood-based research category
- Wood ear group: wood-based research category
Quality checks
tree identity; freshness or storage history; wood treatment; particle size; contamination; moisture; supply legality
Production method records
One species can require more than one cultivation model.
SHI-LOGNatural log cultivation
- Substrate
- verified suitable hardwood logs
- Container
- intact log
- Treatment
- Log selection, conditioning and sanitation are method-specific; no block sterilization step is implied.
- Scale context

- Tree and log suitability
- Log preparation
- Inoculation
- Seal and incubation
- Maturation
- Induction
- Fruiting
- Rest
SHI-BLOCKSterilized sawdust block
- Substrate
- formulated hardwood sawdust
- Container
- heat-compatible filtered cultivation bag
- Treatment
- Sterilization-class treatment inside a validated sterile workflow.
- Scale context
- controlled production with sterile-process capability
- Formulation
- Bagging
- Sterilization
- Aseptic inoculation
- Incubation
- Browning
- Maturation
- Induction
- Fruiting
- Rest
