Yellow morel

Morchella esculenta

Also calledMorille (French) · Gucchi (Hindi/Kashmiri) · Yang du jun 羊肚菌 (Chinese) · Colmenilla (Spanish) · Speisemorchel (German)

A honeycomb-capped spring mushroom, hollow from cap tip to stem base. It is so prized that wild gucchi from Kashmir and Himachal are among the most expensive foods in South Asia. It is an ascomycete, more closely related to truffles than to gilled mushrooms.

Morchella esculenta is a species of fungus in the family Morchellaceae of the Ascomycota. Wikipedia

§1

What it can do

  1. iFruits in a short spring window, often after soil temperatures reach about 10–12 °C
  2. iiProduces sclerotia, hardened stores of hyphae that help it survive and fruit
  3. iiiSome morels fruit in huge numbers on the ground the year after forest fires
  4. ivShoots ascospores from pits on the cap in visible puffs

Eatenwhole fruiting body (thoroughly cooked)

Choice edible, but always cook thoroughly. Raw or undercooked morels cause gastric upset, and some people react even to cooked ones, especially with alcohol. Deadly lookalike: the false morel (Gyromitra esculenta), which has a brain-like, lobed cap and a chambered or cottony interior and contains gyromitrin. Also beware Verpa bohemica, whose cap hangs free like a thimble over a cotton-stuffed stem. A true morel is hollow from tip to base, with the cap attached directly to the stem. Morels from old orchards may contain lead and arsenic from historic pesticides.

§3

Fruiting body & spores

Spores

Ascospores (not seeds), 8 per ascus, ellipsoid, smooth, about 20–24 × 12–14 µm; spore print cream to pale yellow-orange

Dispersal
Ascospores forcibly discharged from the pitted cap and carried by wind
§4

How to cultivate it

Hardiness (USDA zones)

Light
Shade to dappled light
Water
Moist soil in spring
Soil
Loamy, calcareous or ash-enriched soil
Propagation
Spawn on grain; outdoor beds with nutrient bags (method developed commercially in China for M. importuna and related species)
To harvest
Sow spawn in late autumn; harvest the following spring
Climates
Temperate
  1. 1Prepare a shaded outdoor bed of loose loam, ideally with wood ash or lime mixed in
  2. 2Broadcast morel grain spawn in autumn and cover lightly with soil
  3. 3After the mycelium spreads, lay 'exogenous nutrient bags' of moist sterilised grain over the bed
  4. 4Keep the soil damp through winter; fruiting starts when spring soil reaches about 8–15 °C
  5. 5Results are unreliable outside specialised farms, so treat it as an experiment

Woodcuts and engravings matched from the Source Library’s scanned books by name. Plates marked “relative” show a close kin rather than this exact species. Click a plate to read the page it came from, with translation.

§8

Marginalia

Gucchi gathered in the Himalayan foothills is dried on strings and sold at high prices, and gucchi pulao is a Kashmiri feast dish. In Europe, Carolus Clusius described morels in his 1601 account of the fungi of Pannonia (Hungary), the first book devoted to fungi.

Curiosity

When a morel releases spores you can sometimes see the puff of 'smoke' rise from the cap.
