When dealing with older specimens of Boletus betulicola (also known as birch bolete or butter bolete), removing the tubular layer is often recommended for several reasons:
1. Texture: As these mushrooms age, their tubes can become tougher and less palatable, affecting the overall texture of your dish.
2. Flavor: Older mushrooms may develop a more earthy or bitter taste, which some people find undesirable. The tubes are usually where this flavor intensifies.
3. Aesthetic Appeal: Removing the tubes can make the mushroom look cleaner and more appealing on the plate.
To remove the tube layer:
- Use a paring knife or vegetable peeler to carefully scrape away the underside of the cap.
- Alternatively, you can slice off the bottom part of the stem and gently pull back the tubes if they come off easily.
However, if you're confident that the mushrooms aren't overly mature and still have good quality, you might choose not to remove them entirely. Some cooks prefer to leave the tubes intact for added flavor and visual interest.
In summary, while it's not strictly necessary to remove the tubular layer from old Boletus betulicola, doing so will generally improve both the texture and taste of your final dish.

While it's not strictly necessary to remove the skin from Birch Porcini, doing so can result in a more tender and visually appealing dish. It ultimately depends on your personal preference and the specific recipe you're preparing.

Boletus betulicola, commonly known as the Birch Porcini or Birch Bolete, is a delicious edible mushroom that does not typically require pre - boiling before cooking. However, there are some considerations based on personal preference and specific culinary methods:
1. Pre - Boiling for Taste Preference: Some people choose to boil Birch Porcinis briefly (5 - 10 minutes) beforehand to reduce their earthy flavor and remove any potential bitterness. This step can make them milder - tasting but may also result in a slightly softer texture.
2. Par - Boiling for Certain Recipes: If you're preparing dishes where you want to ensure the mushrooms are fully cooked through (like stuffings or casseroles), par - boiling might be beneficial. However, this isn't strictly necessary if you're sautéing or roasting them.
3. General Recommendation: For most recipes - such as sautés, stir - fries, or roasted preparations - Birch Porcinis can simply be cleaned, sliced, and cooked directly without prior boiling.
In summary, while pre - boiling is optional and depends on your taste preferences, it's generally not required when cooking Birch Porcinis.

Main Differences Between Birch Porcini (Boletus betulicola) and Gall Bolete (Suillus variegatus):

1. Habitat
- Birch Porcini: Found predominantly under birches (Betula species), often in mixed forests with conifers or deciduous trees.
- Gall Bolete: Typically grows near pine trees (Pinus species).
2. Cap Coloration
- Birch Porcini: Cap is typically reddish - brown to dark brown, sometimes with a slightly grayish tinge towards the center. It can have a smooth surface that may become sticky when wet.
- Gall Bolete: Cap color ranges from yellowish - brown to orange - brown, usually more vibrant and less uniform than Birch Porcini's cap.
3. Pore Surface
- Birch Porcini: Pores start out white but quickly turn olive - green to greenish - yellow upon exposure to air. They remain firm even after pressing.
- Gall Bolete: Pores are initially pale yellow to creamy - white, turning olive - brown or darker brown with age. When pressed, they tend to bruise blue - gray or blackish.
4. Stem Features
- Birch Porcini: The stem is generally smooth, whitish to light tan, and does not change color significantly when cut or bruised. It might have faint reticulation (net - like pattern) at its upper part.
- Gall Bolete: The stem has a distinct netted appearance (reticulate) over most of its length, especially toward the base. It tends to be paler overall compared to Birch Porcini’s stem.
5. Taste and Odors
- Birch Porcini: Has a mild, pleasant taste with no strong odors.
- Gall Bolete: Often described as having an earthy or slightly bitter taste, which some find unappealing.
6. Spore Print
- Birch Porcini: Produces a dark olive - brown spore print.
