What is the difference between the trompa de puerco and other wild mushrooms?

The trompa de puerco is unique because it is not an independent mushroom but a parasite (Hypomyces lactifluorum) that colonises other mushrooms of the genus Russula and Lactarius, completely transforming their shape, colour and flavour. This differentiates it from mushrooms such as the clavito, the escobeta or the tecomate, which are species with independent development. Its intense orange colour and its shellfish flavour are distinctive.

What does the trompa de puerco taste like?

It has a unique flavour among Mexican mushrooms, slightly sweet, with an aromatic background reminiscent of fresh shellfish, crab or cooked lobster, hence its English name (lobster mushroom). The cooked texture is firm, crunchy and slightly fibrous. It is neither bitter nor spicy. It combines very well with epazote, chile pasilla, chile guajillo, lard and butter in traditional preparations.

How is the trompa de puerco served?

It is prepared roasted on the comal with salt and lime, stewed with epazote, garlic and lard, in mixiotes wrapped with chile pasilla and chile guajillo, in chicken broths in Veracruz, sautéed with butter in contemporary preparations, or battered with egg and stuffed with cheese in Tlaxcala. Its shellfish flavour makes it ideal for replacing crustaceans in vegetarian or Lenten preparations.

Where does the trompa de puerco originate from?

It is native to the temperate pine and oak forests of North America, with a wide distribution in Mexico, the United States and Canada. In Mexico, the main harvesting areas are the forests of the State of Mexico, Tlaxcala, Veracruz, Puebla and Hidalgo, where it fruits between July and October during the rainy season. It needs the presence of host mushrooms of the genus Russula and Lactarius in order to develop.

Trompa de puerco: wild mushroom from Mexican pine forests

What is it?

The trompa de puerco, also known as lobster mushroom in English, hongo langosta or trompita, is a very peculiar edible wild mushroom belonging to the species Hypomyces lactifluorum. Its distinctive feature is that it is actually a parasitic fungus that colonises other mushrooms of the genus Russula or Lactarius, completely transforming their shape and giving them an intense, almost red, orange colour, as well as a firm texture and a flavour reminiscent of shellfish. It grows in the temperate pine and oak forests of central Mexico, especially in the State of Mexico, Tlaxcala, Veracruz, Puebla and Hidalgo, where it is harvested during the rainy season between July and October. Its irregular shape, similar to a pig's snout, gives it the popular name of trompa de puerco. It is one of the most sought-after wild mushrooms in Mexican ethnomycological markets for its unique flavour and seasonal rarity.

Origin and history

The recognition of Hypomyces lactifluorum as a species parasitic on other fungi dates back to the 19th century, when European mycologists began to study it in the forests of North America. In Mexico, its traditional consumption is documented in the centre of the country by ethnomycologists such as Gastón Guzmán, Roberto Garibay Orijel and Adriana Montoya, who have worked with Nahua, Otomi, Mazahua and Totonac communities of the highlands. The trompa de puerco appears in rural markets under various regional names: hocico de puerco, trompita, hongo cangrejo or ñoño in Tlaxcala. Although it is not specifically cited in colonial sources such as Sahagún, the mushrooms it parasitises (Russula and Lactarius) are, traditionally consumed by the Mexica peoples. The transformation brought about by the parasite makes the mushroom firmer and more digestible, eliminating the bitterness and cottony texture of raw Russulas. CONABIO and CONAFOR document Hypomyces lactifluorum as one of the most commercially valued Mexican edible wild mushrooms, with high prices in rural markets and restaurants.

Characteristic ingredients

Hypomyces lactifluorum is a parasitic ascomycete fungus that mainly infects basidiomycete mushrooms of the genus Russula brevipes and Lactarius. On colonising them, it completely covers their surface with a bright orange to orange-red layer, transforms the gills into a smooth or almost imperceptible surface and hardens the flesh, giving it a firm and compact texture. The resulting fruiting bodies measure between 5 and 15 centimetres, have an irregular shape reminiscent of an animal's snout or, according to others, a split lobster (hence its English name). The inner flesh is white, firm and compact, with a slightly marine or shellfish-like aroma. Its cooked flavour is notably different from other mushrooms: slightly sweet, with notes of fresh shellfish or crab, and a crunchy texture that makes it unmistakable. In the cuisine of the Mexican highlands it is prepared roasted on the comal with salt, stewed with epazote and lard, in mixiotes with chile pasilla and chile guajillo, or sautéed with onion and chile serrano. In Veracruz it is added to chicken broths, and in Tlaxcala it is stuffed with cheese and battered with egg.

Cultural significance

The trompa de puerco is one of the most characteristic and celebrated wild mushrooms of the central Mexican highlands. Its distinctive shape, striking colour and singular flavour make it a star of the mushroom fairs held annually in towns such as Cuajimalpa, Tlaxco, Senguio, Ozumba, Acaxochitlán and San Juan de las Huertas. Contemporary Mexican gastronomy has rediscovered this mushroom, incorporating it into the menus of haute cuisine restaurants such as Pujol, Sud 777 and Quintonil, where its shellfish flavour is harnessed for innovative preparations. It is one of the wild mushrooms in the dossier of Mexican gastronomic heritage inscribed by UNESCO in 2010. Economically, the trompa de puerco provides important income to women harvesters from Nahua and Otomi communities of the highlands, with prices that can reach several times that of other mushrooms because of its rarity and demand. Research by the Colegio de Posgraduados and INECOL highlights its role in the non-timber forest economy and in the cultural transmission of ethnomycological knowledge.
