Lactarius deliciosus near Arth: where to look

Lactarius deliciosus: the species in brief
How to tell it
An orange cap marked with darker concentric rings. Bruised areas often turn green. The orange latex is one of the most useful identification features.
Where it grows
Associated with conifers, especially pine, in plantations, woodland edges, grass and moss.
In the kitchen
Often fried, grilled or preserved. In parts of eastern Europe it is also salted. Its firm texture and slightly resinous flavour stand up well to simple cooking.
Nutrition
Low in calories. Nutritional values vary by species, age and preparation.

Common questions
Are there mushrooms in Arth in September 2026?
Today's foraging index is 62 out of 100. It is built from two weeks of rainfall, soil temperature, the length of the dry spell and each species' season, and it updates daily.
Which mushrooms are picked around Arth?
There are too few records for this region to name species yet. We will not list them «from the field guide»: an unconfirmed list looks exactly like a confirmed one and is worth something else entirely.
How accurate is this forecast?
It is a model of weather and season, not an observation of the wood. It answers «is this week worth a trip» well, and it does not know what is growing round the next bend. We measure its accuracy against independent records and publish the result — without that number a forecast stays a promise.
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.
