Foraging forecast: Irkutsk Oblast

Conditions in Irkutsk Oblast in September 2026 are middling, index 47 out of 100; of the species we model, saffron milkcap is closest to its flush. There will be something, but you will have to look: check which of the coming days reads higher and go then.

A seven-day index for the species whose records are confirmed here — 25 of them right now. Flush phases and the factors behind the number, instead of a "chance of finding" percentage we cannot measure. Data updated 17 September 2026, 11:22 BST.

The map is built from the measurement network — one point per sizeable town and more in between. A detailed 2.5 km grid is computed for one region so far: it needs its own run for every cell.

Been out in Irkutsk Oblast? Tell us how it went

No sign-up, five seconds. Reports are visible to everyone and help us check the forecast — where people say “nothing out there” and the model promises a flush, the model is wrong.

How much did you find?
When were you out?

This form does not ask for coordinates. What gets published is the name, the rating and the text — nothing else.

Common questions

Are there mushrooms in Irkutsk Oblast in September 2026?

Conditions in Irkutsk Oblast in September 2026 are middling, index 47 out of 100; of the species we model, saffron milkcap is closest to its flush. There will be something, but you will have to look: check which of the coming days reads higher and go then.

Which mushrooms are out in Irkutsk Oblast right now?

The species list for this region is built from confirmed records in GBIF. As soon as there are enough of them, the species appear here with their own forecast — we do not add a species to a region on a guess.

How is the index calculated?

An index from 0 to 100, built from the last month of weather, satellite woodland data, terrain and the seasonal window of each species. It is not a probability of finding anything: it is how well conditions match what that species needs.

When is the best day to go in Irkutsk Oblast?

Use the seven-day index on this page: pick the day with the higher number, and watch the flush phase — «Building» and «Peak» are the ones worth the drive. Today reads 47 out of 100.

The index is high but I found nothing — why?

The index reads weather and season — things that are the same for tens of kilometres around. It does not know your particular wood, and that is where the mushroom grows. The usual reasons: wrong trees — every species has its own, and no weather makes up for the wrong stand; the wood was felled recently or is young — the mycelium takes years to recover; the spot is picked out — everything near a road or a car park goes over a weekend; the flush has been taken — you came a day after those who came on time; or the flush passed and slugs and larvae got there first, which the model cannot see. The reverse holds too: a low index does not mean an empty wood. It means the conditions are against you, not that there is nothing there.

How the index is calculated, and what the model cannot promise — on the about page.
