Casentinesi Forests: mushroom paradise among flora and fauna

The Casentino Forests, located between Tuscany and Emilia-Romagna, represent one of the most intact and biodiverse forest ecosystems in Italy. This vast territory, which includes the Casentino Forests, Monte Falterona, and Campigna National Park, is a true sanctuary for mycology enthusiasts, offering an extraordinary variety of mushrooms, flora, and fauna.

With a geological history dating back millions of years, these forests have developed a unique ecological balance. The alternation of deep valleys, mountain ridges, and wetlands creates ideal microhabitats for the development of diverse fungal species, many of which live in symbiosis with the roots of ancient trees that populate the area.

According to studies by the National Park, over 1,000 different species of mushrooms have been recorded in this area, some of which are extremely rare. The unique terrain, with elevations ranging from 400 to 1,658 meters, allows for the coexistence of species typical of Mediterranean zones with those of colder mountain areas.

Casentino Forests: a unique ecosystem

Few forests achieve such a rich and balanced ecosystem for mushroom proliferation. Let's discover why.

Geography and climate

The Casentino Forests cover approximately 36,000 hectares, with elevations ranging from 400 meters to the 1,658 meters of Monte Falco. The geographical location and altimetric variety create microclimates that favor the growth of different fungal species.

The climate of the Casentino Forests is particularly favorable for mushroom growth due to:

• High rainfall: with annual precipitation between 1,000 and 2,000 mm, well distributed throughout the year
• Mild temperatures: annual averages between 8°C and 14°C, with cool summers and not excessively harsh winters
• Constant humidity: favored by dense forest cover that reduces evaporation

As reported by the ISPRA, these climatic conditions, combined with the nature of the soils (predominantly acidic and rich in humus), create the ideal environment for mycelial development, allowing many mushroom species to complete their life cycle under optimal conditions.

Forest types

The variety of forest environments is one of the factors that makes the Casentino Forests so rich in fungal biodiversity:

Beech forests

The beech forests cover vast areas of the park, especially between 900 and 1,500 meters. These often ancient woods have unique characteristics:

• Beech (Fagus sylvatica): the dominant species, with specimens reaching 40-50 meters in height
• Sycamore maple (Acer pseudoplatanus): found in cooler, wetter areas
• European ash (Fraxinus excelsior): an indicator of deep, fresh soils

The Casentino beech forests are particularly famous for their "Sacred Forest", one of the oldest ancient beech forests in Europe, recognized as a UNESCO World Heritage Site. In these environments, the humus-rich soil and constant humidity favor the growth of fungal species such as the black porcini (Boletus aereus) and the chanterelle (Cantharellus cibarius), which find ideal conditions here.

Fir forests

The fir forests, predominantly of silver fir (Abies alba), represent another characteristic environment:

• Silver fir (Abies alba): a majestic tree that can exceed 50 meters in height
• Beech: often mixed with fir in transitional zones
• Yew (Taxus baccata): found in the shadiest areas

The fir forests host a unique fungal community, adapted to the needle litter and more acidic soil pH. Here we find species such as the yellowfoot chanterelle (Cantharellus lutescens), which forms noticeable fairy rings in clearings, the parasol mushroom (Macrolepiota procera), which can reach impressive sizes, and the larch bolete (Suillus grevillei), which lives in symbiosis with conifers.

The mushrooms of the Casentino Forests

The Casentino Forests are home to hundreds of fungal species, some of great mycological and gastronomic interest. The variety of environments allows for the presence of both Mediterranean and mountain species, creating one of the richest fungal biodiversities in Italy.

Edible mushrooms

Porcini

The king of mushrooms is present in several species, each with specific ecological characteristics:

Boletus edulis (Common porcini):
A robust mushroom with a light brown cap, white pores that turn yellowish-green with age. It grows under both deciduous trees and conifers, preferring forest edges and clearings. In the Casentino Forests, it reaches exceptional sizes, with specimens exceeding 2 kg in weight.

Boletus aereus (Black porcini):
Characterized by a dark, almost black cap and firm white flesh. It prefers thermophilic oak and chestnut woods but is also found in warmer beech forests in the Casentino. Many consider it the most prized porcini for its intense aroma.

Boletus pinophilus (Pine porcini):
Recognizable by its brick-red cap and stout stem. As the name suggests, it lives in symbiosis with pines but is also found under silver firs in the Casentino. It often grows in groups.

According to a study by the Mycology Study Center, porcini in the Casentino Forests reach exceptional sizes due to the favorable climate and humus-rich soils. Harvesting should be done carefully, cutting the mushroom at the base without damaging the underground mycelium.

Other edible mushrooms

Among other edible species, we find:

Caesar's mushroom (Amanita caesarea):
One of the most prized and recognizable mushrooms, with a bright orange cap and golden-yellow gills. It grows in sparse, sunny woods, often under oaks and chestnuts. In the Casentino, it is relatively rare and should only be harvested when fully developed to avoid confusion with poisonous Amanita species.

Morel (Morchella esculenta):
A spring mushroom with a honeycombed cap resembling a beehive. It prefers sandy soils and disturbed areas like trail edges. It should only be consumed after thorough cooking, as it contains heat-labile toxins.

St. George's mushroom (Calocybe gambosa):
A spring mushroom with a characteristic fresh flour smell. It grows in fairy rings in mountain meadows and forest edges. In the Casentino, it is particularly abundant in the Campigna and Badia Prataglia areas.

Chanterelle (Cantharellus cibarius):
A golden-yellow mushroom with false gills running down the stem. It grows in large groups in beech and fir forests, often forming "fairy rings." It is one of the most sought-after mushrooms for its fruity aroma and meaty texture.

Poisonous and non-edible mushrooms

Warning! The Casentino Forests also host dangerous species that every forager must know:

Amanita phalloides (Death cap):
Deadly, responsible for 90% of fatal poisonings. It has an olive-green or whitish cap, white gills, and a stem with a ring and volva. It grows under deciduous trees, especially oaks and chestnuts. Even a single specimen can contain enough toxins to cause death.

Galerina marginata:
A small brown mushroom growing on decaying wood. It contains the same toxins as the death cap. Often confused with psilocybin mushrooms or small edible species.

Cortinarius orellanus:
A deceptively innocent-looking mushroom with a reddish-brown cap and fibrous stem. It causes irreversible kidney failure. The latency period of symptoms (3-14 days) makes this mushroom particularly dangerous.

For safe identification, always consult the Bulletin of the Bresadola Mycological Association and, in case of doubt, contact local health authority mycological inspectors.

Associated flora and fauna

Mushrooms do not live in isolation but in complex ecological relationships with plants and animals. Understanding these interactions is essential for sustainable and ecosystem-respectful harvesting.

Characteristic flora

Beyond the dominant tree species, the undergrowth of the Casentino Forests hosts rich herbaceous and shrub flora:

Heather (Erica arborea):
An evergreen shrub forming dense thickets in sunnier areas. Its roots host mycorrhizae of various mushroom species, including some Russula. Its spring blooms attract numerous pollinating insects.

Bilberry (Vaccinium myrtillus):
A small shrub forming extensive carpets in beech and fir forests. Its berries are an important food source for wildlife. It lives in symbiosis with mushrooms like Lactarius deliciosus and various Cortinarius.

Ferns:
Several fern species (such as Dryopteris filix-mas and Pteridium aquilinum) indicate particularly humid areas. Their presence is often associated with saprophytic mushrooms like some Mycena species.

Epipactis helleborine:
A wild orchid living in close association with mycorrhizal fungi of the Rhizoctonia genus. Its presence indicates rich, well-structured soil.

Undergrowth fauna

Numerous animals interact with mushrooms, contributing to spore dispersal and organic matter decomposition:

Wild boar (Sus scrofa):
Roots primarily for truffles and other hypogeous fungi but does not disdain epigeous mushrooms. Excessive digging can damage surface mycelium.

Red squirrel (Sciurus vulgaris):
Stores dried mushrooms on trees to consume during winter, unknowingly aiding spore dispersal. Prefers porcini and other firm-fleshed species.

Fungivorous beetles:
Numerous insect species (like Bolitophagus reticulatus) complete their life cycle inside mushrooms. Their larvae tunnel through the flesh, accelerating decomposition.

Snails:
Various gastropod species feed on mushrooms, preferring softer, wetter ones. They often leave characteristic slime trails on cap surfaces.

Sustainable harvesting and regulations

Mushroom harvesting in the Casentino Forests is regulated to preserve the ecosystem and ensure species reproduction.

Basic rules for sustainable harvesting

To maintain the mycological balance of the park, it is essential to follow simple rules:

Quantity:
A maximum of 3 kg of mushrooms per person per day is allowed. This limit was established after scientific studies showed that larger quantities would compromise fungal reproductive capacity.

Tools:
Rakes, hoes, or other tools that damage mycelium are prohibited. A small knife is ideal for cutting the mushroom at the base, leaving the underground part intact.

Permits:
A daily or seasonal permit, issued by Mountain Communities or Park offices, is mandatory. Checks are frequent, and penalties for violations can be severe.

Transport:
Mushrooms should be carried in ventilated containers (like traditional wicker baskets) to allow spore dispersal during transport.

Protected species:
Some species (like Caesar's mushroom in certain areas) have specific restrictions. It is essential to check with Park offices before harvesting.

Best harvesting periods

Ideal seasons vary with altitude and annual weather conditions:

According to data from the National Park, years with particularly rainy springs and not too dry summers guarantee the best autumn harvests. The golden period generally runs from mid-September to late October.
