Simbiosis Tours 2026 — Last forays of the season

Identification table with wild mushrooms, a hand lens and printed guides during a Simbiosis tour

The season is entering its final stretch. These are the last forays of the year, guided by Arif Towns Alonso: two weekends in the Sierra de Guanajuato and the closing weekend at Rancho Calixto, Amealco, Querétaro.

We walk, we forage, we identify and we read the forest. Write to us for times, meeting point and availability: groups are small.

The two forests

Where we walk

  • Sierra de GuanajuatoSanta Rosa de Lima, Guanajuato. Our home forest: hiking, foraging, identification and interpretation of mushrooms.
  • Rancho CalixtoAmealco, Querétaro. Eighty hectares of oak and pine run as a Wildlife Conservation Management Unit: a day of observation, recording and identification, reading the forest without taking it home. What you observe is added to the Rancho Calixto project on iNaturalist.

What this year has already given us

August was the peak of the fungal year and we lived all of it: the Kids tour in the Sierra de Santa Rosa; the mushrooms and cooking in the forest day with Nelcy Martínez and Jesús Arellano, chefs at Agavia; the Cuatro Fuegos, Un Micelio dinner alongside Agavia, Cañita and Garnacha; and Fungidencias, our Fungi Kingdom festival at Rancho Calixto, Amealco, with a signature dinner by chef David Jahnke. In September we took the forest to the city as exhibitors at the Biofunga Fest.

The full chronicles, with photographs and video, live in the Bitácora Fungívora: How Hongosto 2026 unfolded and Biofunga Fest 2026 chronicle.

After the forest

Every mushroom you photograph on the trail can become science: uploaded to our citizen science project on Naturalista, your find joins CONABIO's national biodiversity record. Walking with us is also becoming a fungivore.
