Mythical Mushrooms

Termitomyces schimperi

 

 

Whilst we wait for the next batch of Snapshot Serengeti images to be processed and posted up for us to classify I thought I would regale you with a short tail from my recent field work in Namibia. I was based on a cattle farm near to the small town of Otjiwarongo. One of the highlights, apart from the wealth of wildlife living alongside the cattle came as a total surprise. Mushrooms, giant, dinner plate sized tasty mushrooms.

Who would have thought to discover such a delicacy in the thorny scrubby bush of north eastern Namibia, a place normally thought of as desert.

I was out driving the boundaries of the farm with the owners one Saturday morning when they came to an abrupt stop and started reversing backwards. When we stopped they jumped out as if for action crying Omajowa! Thinking this was some Herero word for poacher or something similar I prepared myself for action too following them towards a very tall termite mound.

Omajowa were no poachers, they were giant mushrooms growing all around the base of the termite mound and according to my hosts, delicious. They expertly plucked a few out to take home for dinner and to share amongst the staff. We ate them cut into large chunks, breaded then fried like a schnitzel. Yes they were a taste to behold I can tell you.

The Ejova (singular, Herero name) or termitenpilz (German Namibian name) is the mushroom species Termitomyces schimperi. Termitomyces species are found over much of West, East and Southern Africa and live in association with various termite species.

In Namibia omajowa are found on the mounds of the termite Macrotermes michaelseni that build very tall mounds reaching heights of 5 meters tall. It has been noted that these often incline to the north.

The termites cultivate the fungus by providing a perfect substrate and perfect microclimate for the fungus to grow whist eliminating any competitors to the fungus. In return the fungus helps break down plant material aiding the efficient uptake of nutrients for the termites as well as providing additional food sources from its own body that are rich in nitrogen.

The omajowa, like most fungus is for the most part concealed away below ground but when conditions are right, in this case after a good rainfall between December and March the more familiar fruiting body emerges from the base of the termite mound growing on a stalk up to 50cm high with a cap that can reach 40cm diameter. Usually in groups of 5 to 10 up to 50 on one termite mound have been recorded in Namibia. They are really quite a sight.

From a cultural perspective they are seen by Namibians as a symbol of growth and prosperity and they are eagerly sought out. It is not unusual to see someone standing on the road side hefting one of these giants up in the air in an invitation to stop and buy from him.

Once pulled from the ground they have a strangely alien appearance with the dangling pseudorhiza (root like structure) still attached, though it is probably more ecologically sound to leave most of the pseudorhiza behind. The termites will feed on this and the remaining fungus will carry on growing to pop up another year. Like everything in nature, sustainable thoughtful use should be practiced in order preserve the delicate balance of life.
