True milk cap. Shubin 1976: birch and mixed woods; “milk caps” July–September. Black milk cap is a separate account, not this product. Start 1 July; end 30 September. Matching Leningrad Oblast (catalog July–September) is independent month-level compression, not a copied row. No explicit peak. Moscow is not copied.

Layer calendar compiled for Petrozavodsk latitude (not Leningrad Oblast): 1st layer second half of June, short and few; 2nd 1st–2nd decades of July; 3rd from 2nd decade of August through October, often peaking in September. Same-book species accounts: chanterelle July–October; birch and aspen bolete June–October; true milk cap July–September (black milk cap separate); saffron milk cap July–October; autumn honey fungus abundant about two weeks, usually first half of September (1968 early August is an exception). Summer honey fungus June–August is not this product. Porcini is not modelled from this row (1986 monograph). Catalog morel (Morchella) uses a separate source row; April–May Gyromitra is not that product.

True milk cap. 2015: Lactarius resimus July–September; mass collection 11 September 1993; also 5 and 26 July 1995. Start 1 July; end 30 September. Matching Karelia at month level is independent reserve-catalog reading, not a copy of Shubin. No explicit peak (one-off pick dates ≠ a stable peak window). Black milk cap is not this product.

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.
