Porcini are fried and stewed and added to soups and sauces. The dense flesh holds its shape well when pan-fried. The mushrooms are also dried.

Porcini. Shubin 1986 (Forest Institute of the Karelian Branch of the USSR Academy of Sciences): main crop August–September; main decades from the 3rd of July (young blueberry pine, herb-rich birch) through the 3rd of September (mature pine). Start 21 July is the first main-yield decade, not sparse June. End 30 September. Rare October tails and Moscow handbooks are omitted. No explicit peak: available sources do not justify a narrower window without false precision.

Porcini monograph. Plots from 1959 (Kivach, then districts of the republic and Murmansk Oblast). Fruiting June–October; June usually short and not abundant; main crop August–September. Habitat decades: young blueberry pine 3rd July–3rd August (max 2nd August); mature pine 1st August–3rd September; herb-rich birch 3rd July–1st September. Notes are Karelian porcini only; Moscow Smirnyakov/Gorlenko and other catalog species are not from this book.

Porcini. 2015: Boletus edulis and B. pinophilus both June–October. Start 21 June (not 1 June); end 15 October. Shubin 1986 Karelia and Moscow are not copied. Izhora August–September occurrence months are too narrow and are not used as the window. No explicit peak: available sources do not justify a narrower window without false precision.

Annotated list of 806 species, north-east Leningrad Oblast (Lodeynopolsky District, middle taiga), not the whole subject and not the Karelian Isthmus. Chanterelle June–October, very frequent; porcini and pine porcini June–October; birch bolete June–September, very frequent; aspen bolete July–September; northern honey fungus (Armillaria borealis) August–September, layer usually short; saffron milk cap August–October, rather rare (1993 plot layer 2–15 October); true milk cap July–September. Morel is rare; 28 June 1993 mass on a burn is not a typical oblast harvest. Shubin’s Karelian calendar and Moscow handbooks are not copied.

Smirnyakov 1992: first bodies in the 3rd decade of June, abundant mid-August to early September, mass through the 1st decade of October. Gorlenko 1986: June–October. End omits late-October “warm autumn only”. This is an envelope of typical layers, not continuous picking. No explicit peak: available sources do not justify a narrower day window without false precision. Leningrad and Voronezh are not copied.
