Termitomyces, the termite mushrooms, is a genus of basidiomycete fungi belonging to the family Lyophyllaceae. All of which are completely dependent on fungus-growing termites, the Macrotermitinae, to survive, and vice versa.[3] They are the food source for these termites, who enjoy an obligate symbiosis with the genus[4] similar to that between Atta ants and Attamyces mushrooms.

Characteristics

These mushrooms are edible, and are a popular wild food where they occur. They include the largest edible mushroom in the world, Termitomyces titanicus of West Africa and Zambia, whose cap reaches 1 metre (3.28ft) in diameter. These fungi grow on 'combs' which are formed from the termites' excreta, dominated by tough woody fragments. Termitomyces was described by Roger Heim in 1942.[5]

From 1955 to 1969 Arthur French [6] worked in Uganda (as a hobby) on the subject of fungi and termites. Some scientific literature about these fungal species existed previously, but these texts failed to adequately discuss the relationship between termites and their fungal symbiotes, while the various edible varieties were merely termed "termite mushrooms." French conducted some investigations with the help of the elderly Baganda women who gathered termite mushrooms, and published his findings.

Life as a Termitomyces fungus

The termites collect and chew up dead wood, leaf litter and other vegetable debris, depositing their faeces in the fungus garden situated in a central chamber of their nest. The hyphae of the fungus grow through the comb and the termites feed on the fungal threads. Periodically the fungus sends hyphae to the surface of the ground where mushroom-like fruiting bodies are formed.[7][8] Mostly, the fungus is introduced into a newly established termite colony through the activities of the termites collecting spores from the environment.[4] That is, spore transfer is accomplished mainly by shedding from mushrooms, which protrude from the termite mounds.[9]

Unlike ones of other Termitomyces fungi, the fruiting bodies of T. microcarpus grow from pieces of fungus garden that are carried outside the nest by worker termites.[10]

Taxonomic identity unknown

  2. Termitomyces meipengianus (M. Zang & D.Z. Zhang) P.M. Kirk (2014)
    • Not a Termitomyces; the actual taxonomic identity of this mushroom is unclear.[12]

Misnomer

  1. Termitomyces albuminosus (Berk.) R.Heim (1941)
    • This name is commonly misused to refer to mushrooms of Termitomyces;[13][14] the original specimen of T. albuminosus was deemed to be a Macrolepiota and its species name became M. albuminosa.[15]

Other fungi associated with fungus-growing termite

  • Fungi of subgenus Pseudoxylaria of Xylaria grow from deteriorating or deserted fungus-growing termite comb. Pseudoxylaria species can be easily distinguished from those of Termitomyces in that Pseudoxylaria fruiting bodies are either forked-shaped, or stick-shaped, while those of Termitomyces resemble a stereotypical mushroom or toadstool.

Lookalikes

Culinary use

This genus is a popular seasonal delicacy in the Indian state of Goa. For about two weeks at the beginning of August every year, clusters of villagers dot the Goan roadside hawking the handpicked mushrooms. A spicy gravy known as "Tonak" is a popular method of preparation. Since Termitomyces mushrooms are difficult to mass produce, they command a high price.[17]

Mushroom sellers in Panjim Goa

They are also foraged in Malaysia known as cendawan busut ("mound mushroom"). Tamil rubber tappers in Selangor long time ago would find a lot of T. schimperi growing in estate environments not long after raining.[18]: 81
