Mushroom season calendar

How to use this calendar: A highlighted month means that the species is commonly plausible within the broad planning profile used by Mushroom Hunter. It does not guarantee fruiting, identification, access or safe consumption. Elevation, region and the current year can shift every window.

Read the month, then check the conditions

A season calendar is a useful first filter because it prevents a weather signal from being interpreted without biological context. Rain and moderate temperature in January do not create a normal porcini season. At the same time, a highlighted September cell cannot overcome a prolonged drought. Use the month to decide whether a search is broadly credible, then examine recent rainfall, temperature, humidity, wind and habitat.

The visual rows use the six species profiles currently available in the app’s Where to go feature: Cep / Porcini, Golden chanterelle, Parasol mushroom, Caesar’s mushroom, Scaly wood mushroom and Field mushroom. The encyclopedia contains more species, but they are not automatically part of the destination model.

What “season” means

Season is a broad period in which fruiting is more plausible. It reflects the normal relationship between the fungus, host or substrate, soil temperature and moisture. Peak months indicate a stronger general window in the current profile. They are not harvest appointments. A species may appear outside the peak after unusual weather, and fail completely during a peak month.

Latitude and elevation shift the timing. Low warm areas often develop earlier in spring, while high forests warm later and may retain useful moisture into summer. In autumn, exposed mountain locations can receive frost before sheltered valleys. Regional species differences and local forest history add more variation.

Rainfall is a sequence

Recent accumulated rain is more informative than the icon for today. One storm after drought may wet only the surface. Repeated moderate rain can restore deeper moisture, while excessive rain can create saturated ground and unsafe access. The canopy also intercepts water, and local thunderstorms can fall between weather grid points.

In the app, seven-day rainfall is shown as a separate factor. Read it alongside the season row. “In season” plus “Limited rain” explains why a forest can receive only a modest total score. A “Good” rain value still needs a suitable forest or grassland and field verification.

Temperature, humidity and wind

Temperature affects fungal development and evaporation. Each supported species has its own useful range, so the same afternoon can be favourable for one and weak for another. Recent averages are more useful than a single daily maximum. Cool nights, warm soil and sun exposure can produce different conditions within one forecast area.

Humidity slows drying but does not replace soil moisture. Wind accelerates evaporation on ridges, clearings and forest edges. These factors are therefore supporting context rather than independent proof. Mushroom Hunter exposes them separately so users can understand the score instead of relying on an unexplained percentage.

Forest type and ecological differences

Porcini and chanterelles are forest mycorrhizal groups with broadleaf, coniferous or mixed associations depending on species and region. Caesar’s mushroom is weighted toward warmer broadleaf and suitable mixed forest in the app. Scaly wood mushroom is evaluated as woodland with a strong conifer component. Parasol mushroom favours forest edges, while field mushroom is a grassland species.

That difference is why one calendar cannot be used without habitat. A field mushroom month should lead to a grassland search, not the centre of a forest polygon. A chanterelle month should trigger a check for compatible woodland, moisture and drainage. The correct first step is always to select the target species.

Regional and yearly differences

A national calendar necessarily simplifies. Mountains, coastal influence, plains and sheltered valleys can follow different patterns. Drought, late snow, heatwaves, repeated summer storms and early frost move the productive period from year to year. Climate trends also make historical dates less reliable when used without current conditions.

For Bulgaria, compare this page with the Bulgaria mushroom hunting overview. It explains why mountain and lowland forests can be in different phases on the same date. For any location, trust current field evidence over a coloured month cell.

A calendar-to-map workflow

1. Choose one supported mushroom and check whether the month is within its broad season.
2. Open Where to go? and set a realistic search radius.
3. Compare mapped candidates by confirmed habitat, seven-day rain, temperature, humidity and wind.
4. Review access and route safety independently before opening navigation.
5. Verify trees, substrate and moisture on arrival; record both successful and unsuccessful visits.

For species-specific detail, continue to the porcini or chanterelle page. The calendar tells you when a search may be reasonable; those pages explain where and why.

Limits and safety

A season indicator does not identify any mushroom. Many poisonous species fruit during the same months and in the same forests as edible species. Never consume a wild specimen based on timing, colour, habitat or an AI suggestion. Examine the complete mushroom and consult a qualified local expert.

A promising month also says nothing about legal access. A destination can lie near private land, forestry activity, a protected area or temporary restrictions. Check current local information, weather alerts, fire risk and hunting notices before travelling.
