Termitomyces schimperi is a large mushroom associated with the termite species Macrotermes michaelseni . It grows in the northern part of Southern Africa, from northern Namibia up to Democratic Republic of Congo (DRC), eastwards to Malawi and Mozambique, and westwards to Ivory Coast. [2] [3] [4]

Contents

In Namibia it is commonly referred to by its Herero name Ejova (singular)/ Omajowa (plural). German Namibians refer to the mushroom as "Termitenpilz." [5]

Characteristics

Termitomyces schimperi can grow to the size of a "large frying pan". [2] When they emerge, the fruitbody of the fungus are the "size of a man’s fist", before rapidly expanding to 15–28 cm and sometimes reaching 40 cm in diameter. [5] The tops are white. Yellowish to red-brown discolouration of the thick soft scales may occur by the mound soil. [5] Below the top most layer, the scales are white. [5] The pseudorhiza (a cord-like structure resembling a plant root) is narrower at its origin in the termite nest, and may be as long as 90 cm. Its consistency above ground is less dense. The sporocarps can be seen in groups of 5–10 around the lower parts of termite mound, and grow to around 50 cm above soil level. Up to 50 sporocarps have been reported around a single mound. The Termitomyces schimperi usually appear after soaking rains of 12 mm or more during spring, but the main crop develops during January to March which is the main rainy season. If the hyphae remain in the mound when harvested, they may grow on the same termite mound for many years. The termites consume the partial veil following maturation of the fungus. [5]

Termite association

Termitomyces schimperi do not appear on all termite mounds. [5] When present, they have been recorded on termite mounds of central and northern Namibia in areas with an average rainfall over 350 mm. The mounds can often extend to 3-4 m in height with their apices inclined towards the north. The associated termite is Macrotermes michaelseni (Sjöstedt, 1914). [5] (This termite is recorded in some literature [See [5] ] as "Termes bellicosus", a misapplied name, where some former subspecies are since treated as junior subjective synonyms of Macrotermes michaelseni ).

In Zambia the Termitomyces schimperi can also be found on termite mounds of the termite Odontotermes patruus (Sjöstedt, 1913). [5]

Cultural association

The mushroom is seen as a symbol of growth and prosperity by Namibians and is highly valued in Namibian culture. [6] Their popularity in Africa is reflected in their appearance on postage stamps. [7] It has high value as an edible source in the Ivory Coast. [4]

Edible mushrooms are the fleshy fruit bodies of several species of macrofungi. Edibility may be defined by criteria including the absence of poisonous effects on humans and desirable taste and aroma. Mushrooms that have a particularly desirable taste are described as "choice". Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor.

<span class="mw-page-title-main">Mound-building termites</span> Group of termite species

Mound-building termites are a group of termite species that live in mounds which are made of a combination of soil, termite saliva and dung. These termites live in Africa, Australia and South America. The mounds sometimes have a diameter of 30 metres (98 ft). Most of the mounds are in well-drained areas. Termite mounds usually outlive the colonies themselves. If the inner tunnels of the nest are exposed it is usually dead. Sometimes other colonies, of the same or different species, occupy a mound after the original builders' deaths.

<i>Termitomyces</i> Genus of fungi

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. They are the food source for these termites, who enjoy an obligate symbiosis with the genus similar to that between Atta ants and Attamyces mushrooms. Termitomyces mushrooms are edible, and are highly regarded for their flavor.

<span class="mw-page-title-main">Fungivore</span> Organism that consumes fungi

Fungivory or mycophagy is the process of organisms consuming fungi. Many different organisms have been recorded to gain their energy from consuming fungi, including birds, mammals, insects, plants, amoebas, gastropods, nematodes, bacteria and other fungi. Some of these, which only eat fungi, are called fungivores whereas others eat fungi as only part of their diet, being omnivores.

<i>Podaxis pistillaris</i> Species of fungus

Podaxis pistillaris is a very distinctive relative of the puffballs. It is commonly known as the desert shaggy mane, as it bears a superficial resemblance to the shaggy mane, Coprinus comatus; this species lacks the latter's deliquescing gills, however, and the two are not closely related. It grows to 15 cm high and has a hard, woody stem. The large cap, which protects the blackish spore-bearing tissue, splits, and usually falls away at maturity, allowing the spores to be dispersed by wind. Large numbers may appear after soaking rains. It thrives in deserts and semi-deserts of Australia and other countries, often found on termite mounds in South Africa. In the Hawaiian Islands, it is frequently encountered along roadsides and in disturbed areas on the dry sides of the islands, especially in the Kona area of Hawaii and the Kihei area of Maui.

<i>Termitomyces titanicus</i> Species of fungus

Termitomyces titanicus is a species of fungus in the Lyophyllaceae family. Found in West Africa, it has a cap that may reach 1 metre (3 ft) in diameter on a stipe up to 22 inches (57 cm) in length. Termitomyces is symbiotic with termites of the genus Macrotermes who raise the hyphae upon partially digested leaves as their primary foodstuff. T. titanicus was unknown to Western science prior to 1980, even though it was a common item in the native markets. Pegler and Piearce made no attempt to explain its late discovery.

<i>Geopora cooperi</i> Species of fungus

Geopora cooperi, commonly known as the pine truffle or the fuzzy truffle, is a species of fungus in the family Pyronemataceae. It has a fuzzy brown outer surface and an inner surface of whitish, convoluted folds of tissue. Widely distributed in the Northern Hemisphere, the species has been recorded from Asia, Europe, and North America.

J. Scott Turner is an American physiologist who has contributed to the theory of collective intelligence through his fieldwork on the South African species of termite Macrotermes michaelseni, suggesting the architectural complexity and sophistication of their mounds as an instance of his theory of the extended organism or superorganism. His theory was reviewed in a range of journals, including Perspectives in Biology and Medicine, the New York Times Book Review, EMBO Reports, and American Scientist.
