About Suillus granulatus Mycelium

Suillus granulatus, commonly known as the Weeping Bolete, is a mycorrhizal fungus in the family Suillaceae. Its mycelium forms ectomycorrhizal associations primarily with pine trees, most commonly Scots pine (Pinus sylvestris), playing a role in nutrient exchange within pine forest ecosystems.

The mature mushroom (not included in this sale) is characterized by:

Yellow to yellow-brown caps with a smooth, often viscid surface

Pore surface instead of gills, typical of boletes

Fine granular droplets sometimes visible on young pore surfaces

Growth in pine forests, forest edges, and sandy soils

This product contains MYCELIUM ONLY, representing the initial developmental stage of the fungus.

Natural Growing Conditions

In nature, Suillus granulatus mycelium develops in:

Pine-dominated forests

Sandy or well-drained soils

Mildly acidic substrates

Temperate climates

Fruiting typically occurs from late spring through autumn, depending on environmental conditions.

Cultivation Context (Mycelium Use)

This mycelium is suitable for outdoor cultivation in pine-associated environments that reflect its natural ecology.

Typical environmental features include:

Presence of pine trees, especially Pinus species

Loose, well-drained forest soil

Moderate, consistent soil moisture

Shaded to semi-shaded locations

Care & Environmental Considerations

Maintain natural soil moisture
