Spring Liquid Culture 5 Pack — Pack Overview
The Spring Mushroom Cultures 5 Pack is built around the species that define the spring foraging season in temperate North America. Three morel species for the classic spring hunt season that runs from March through May, Giant Puffball for the open ground emergence that follows in late spring, and Maitake as the bridge to the oak forest floor that produces from spring establishment through fall harvest. Together these five species give cultivators a complete spring-focused cultivation collection.
Spring Liquid Culture 5 Pack — Included Species
Yellow Morel (Morchella esculenta) Liquid Culture
Yellow Morel is the spring morel, the honeycomb-capped, hollow-stemmed fungus that drives more people into the woods from March through May than any other species. We have been selling verified yellow morel liquid culture for years. The outdoor bed cultivation pathway, including grain spawn production and sclerotia development, is what the grow guide covers in detail.
Yellow Morel — Out-Grow Lab Notes
| Parameter | Out-Grow Notes |
| Culture medium | LME + dextrose, 2% + 2% in distilled water |
| Cultivation | Outdoor bed inoculation; sclerotia formation required before any fruiting |
| Season | Spring — March through May in most of North America |
| Inoculation rate | 2 to 3cc per quart of sterilized grain or hardwood substrate |
| Storage life | 6 or more months at normal room temperature |
Yellow Morel Taxonomy
- Kingdom: Fungi
- Division: Ascomycota
- Class: Pezizomycetes
- Order: Pezizales
- Family: Morchellaceae
- Genus: Morchella
- Species: Morchella esculenta
Black Morel (Morchella angusticeps) Liquid Culture
Black Morel is the eastern North American species most people are actually finding under ash trees each spring, even when they call it yellow morel. Morchella angusticeps, the true North American wild type, not Morchella importuna. It tends to emerge slightly earlier in the season than yellow morel and in different habitat preferences that make it a distinct target for outdoor cultivation projects.
Black Morel — Out-Grow Lab Notes
| Parameter | Out-Grow Notes |
| Culture medium | LME + dextrose, 2% + 2% in distilled water |
| Cultivation | Outdoor bed inoculation near ash, elm, and tulip tree |
| Season | Early spring — often before yellow morel in the same region |
| Species note | True eastern North American wild type, not M. importuna |
| Inoculation rate | 2 to 3cc per quart of sterilized grain or hardwood substrate |
| Storage life | 6 or more months at normal room temperature |

- Genus: Morchella
- Species: Morchella angusticeps
California Landscaping Morel (Morchella rufobrunnea) Liquid Culture
The California Landscaping Morel is the morel with documented indoor fruiting potential, the only truly saprotrophic morel species in this pack. It earned its common name from its habit of appearing in landscaped areas with woodchip mulch, which is exactly the kind of substrate that works for outdoor bed cultivation. It is the species we recommend most often to cultivators who want the best chance of producing morel fruiting bodies from liquid culture.
California Landscaping Morel — Out-Grow Lab Notes
| Parameter | Out-Grow Notes |
| Culture medium | LME + dextrose, 2% + 2% in distilled water |
| Indoor fruiting | Documented — only morel in this pack with published indoor protocol |
| Visual ID | Bruises reddish-orange on contact |
| Best for | Cultivators wanting the best fruiting odds from morel culture |
| Inoculation rate | 2 to 3cc per quart of sterilized grain or hardwood substrate |
| Storage life | 6 or more months at normal room temperature |

Giant Puffball (Calvatia gigantea) Liquid Culture
Giant Puffball follows morel season in the spring foraging calendar, appearing on open ground and woodland edges as temperatures climb through late spring. It is the most accessible outdoor cultivation target in this pack, it establishes in garden beds, spreads mycelium through the soil, and returns each season without reinoculation once established.
Giant Puffball — Out-Grow Lab Notes
| Parameter | Out-Grow Notes |
| Culture medium | LME + dextrose, 2% + 2% in distilled water |
| Season | Late spring through early summer in most climates |
| Establishment | Returns each season once established — no reinoculation needed |
| Inoculation rate | 2 to 3cc per quart of sterilized grain or hardwood substrate |
| Storage life | 6 or more months at normal room temperature |

- Kingdom: Fungi
- Division: Basidiomycota
- Class: Agaricomycetes
- Order: Agaricales
- Family: Agaricaceae
- Genus: Calvatia
- Species: Calvatia gigantea
Maitake (Grifola frondosa) Liquid Culture
Maitake rounds out the spring collection as the species whose outdoor oak establishment work begins in spring, inoculate stumps in spring, and the multi-season development begins. While harvest comes in fall, the spring establishment is where the cultivation project starts, which is why it belongs in a spring-focused pack.
Maitake — Out-Grow Lab Notes
| Parameter | Out-Grow Notes |
| Culture medium | LME + dextrose, 2% + 2% in distilled water |
| Season | Spring inoculation; fall harvest in established sites |
| Best approach | Outdoor oak stump inoculation — start in spring for fall harvest |
| Inoculation rate | 2 to 3cc per quart of sterilized grain or hardwood substrate |
| Storage life | 6 or more months at normal room temperature |
Maitake Taxonomy
- Kingdom: Fungi
- Division: Basidiomycota
- Class: Agaricomycetes
- Order: Polyporales
- Family: Meripilaceae
- Genus: Grifola
- Species: Grifola frondosa
Spring Liquid Culture 5 Pack — Cultivation Overview
Three of the five species in the Spring pack are morel cultures requiring outdoor bed methodology with multi-season timelines. Giant Puffball is the most accessible outdoor cultivation target. Maitake is a long-term oak stump project. All syringes ship from our McConnell, Illinois lab ready to inoculate.
