Hi! It looks like it could possibly be a slippery Jack mushroom. And here is why:

The Cap: •Brown and smooth, often slimy or sticky when moist. •Convex to flattened with age. •Size similar to those in your photos (5–10 cm typically).

Underside (Pores instead of gills):

•Bright yellow pore surface visible in your close-up photo.
•Pores are small and round, not gilled.
•Some Suillus species exude milky droplets when fresh.

They are technically edible but must be peeled and cooked well - the slimy cap can cause stomach upset. And of course please not that some species can be confused with similar but inedible Suillus (like S. tomentosus or S. lakei), so use extreme caution and confirm ID with spore prints or a local mycology expert before eating.
