What is this enigmatic mushroom, a beautiful orange, of medium size, with a flat hat protecting large geometric pores? Species pantropicale, Favolaschia calocera comes from Southeast Asia, and is spreading more and more in Europe. This Basidiomycète from family Mycenaceae settles in our undergrowth.

Description of Favolaschia calocera

The cap of the orange pore mushroom can measure up to 2 cm in diameter, it is first of all yellowish and then takes an orange or yellowish-brown color. Very thin, its underside is marked with large pores measuring between 0.3 and 2.5 mm. The margin is serrated by the presence of pores at the edge of the hat. These pores, the outline of which is pruinose, are arranged in a geometrical configuration of the hexagonal type, a very particular characteristic specific to this species. Concoloured with the hat, the foot is up to 1.5 cm high, it is placed laterally relative to the hat. It is slightly velvety with white and its base is a little wider than the top of the foot. The flesh is thin and orange. Its smell and flavor have not been described.

Determination of Favolaschia calocera

Few cases of confusion are possible with Favolaschia calocera, its orange color with large pores which more or less deform the hat allow easy recognition. In addition, its recent appearance in France and Europe still makes it particularly unknown and little described. However, two species of Favolaschia may look like him. Favolaschia pustulosa globally has the same morphology but its color is whitish. Favolaschia thwaitesii, a very little described species (and probably absent in Europe) seems to be very close to Favolaschia calocera.

Environment of the orange pore fungus

This species develops initially in the pantropical hot zones at the time of the rains. In Europe it is possible to find it under hardwoods or in mixed forests, colonizing stumps and branches of dead wood. It often grows in groups of a greater or lesser number of individuals. This species would be found between June and November but its development period, still little known, could prove to be more extensive.

Did you know ?

Favolaschia calocera is a species from pantropical regions. She recently arrived in France, with a first appearance noted in 2015. She seems to adapt very well to the colder and temperate environments present in Europe. Problems are starting to arise due to its invasive nature. Indeed, its expansion seems rapid and it adapts to any type of woody support. In its original habitats it has even produced toxic substances to ward off competition with other fungi.

Species and varieties of Favolaschia

In the world there are more than 50 species of Favolaschia but most are little known and therefore little described:

  • Andean favolaschia : brown-ochraceous hat, Panama
  • Favolaschia aurantiaca : white hat, Panama
  • Favolaschia deabalta : orange hat, Panama
  • Favolaschia gaillardii : reddish orange hat
  • Favolaschia pantherina : reddish brown hat
