Scutellinia scutellate, commonly known as eyelash cup, molly eye-winker, scarlet elf cap, or eyelash fungus, grows gregariously, or in clusters, and sometimes in dense swarms on moist hardwood logs, sometimes near water or marshy places.

Citizen scientists and nature lovers who are serious and enthusiastic about fungi, can now sit back and relax with a copy of the recently published nature guide titled FField guide to mushrooms & other fungi of South Africa (Penguin Random House Struik, Cape Town).

Dr Marieka Gryzenhout, a C-rated scientist and Senior Lecturer in the Department of Genetics at the University of the Free State (UFS), co-authored the book with Gary Goldman, amateur mycologist from Cape Town.

The book contains descriptions of 200 species and extensive background information and tips on fungi.

‘They are all beautiful to me’

Dr Gryzenhout says fungi are her passion, both small and large. “Interest in mushrooms is currently booming in South Africa, and there was thus a great need to bring out a book with more species than my previous book, Pocket Guide to Mushrooms of South Africa, published in 2010.”

The latter is the first book that Dr Gryzenhout published on South African mushrooms. The book is still available in stores and she is currently revising it.

She does not have a favourite mushroom or fungus, “because they are all beautiful to me”, she states. In the book she published with Goldman, they cover, among others, general information on what fungi are – since very few people know about them. The book also serves as an identification guide, with a range of photographs for each species to make identification easier. 

Goldman furthermore added his flair and expertise, with general information on how to forage for mushrooms (hunting for mushrooms) for the dinner table, together with some tasty recipes.

“Citizen scientists are mostly interested in the edible fungi and mushrooms. However, they are beautiful and conspicuous, and it is gratifying to find them and actually being able to identify this rather ill-studied group,” adds Dr Gryzenhout.

Contributions of citizen scientists helpful

She says, in general, people were overjoyed that another guide on mushrooms was finally published. Dr Gryzenhout continues: “The excellent range of photographs, contributed by a variety of citizen scientists, were stunning and helpful.  In the time when the book came out, no less than seven mushroom-related societies were brought to life by citizens due to the rapidly growing interest in fungi and the need for information. A follow-up to the book is already needed!”

She says the book is bought as gifts and prizes in these societies, “which we are really humbled about. Since the book contains a number of first reports for South Africa as well as a range of edible and poisonous fungi, it is also important for biodiversity and human health.”

More than 1 500 copies of the book have already been sold since is appearance.

Consumer Science at the UFS awards three PhDs

For the first time in its history, the Department of Consumer Science in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) earned three doctorates at one graduation ceremony this year. This week three PhDs were awarded to Ismari van der Merwe, Natasha Cronje, and Gloria Seiphetlheng at the Winter Graduation that took place on the Bloemfontein Campus.

Electrochemically-activated water is widely used in the food and other industries, due to its excellent environment-friendly properties. However, it is not used in the textile industry yet, because too little research has been done to determine the possible positive and negative impact it may have on textiles.

With the thesis, The evaluation of catholyte treatment on the colour and tensile properties of dyed cotton, polyester and polyamide 6,6 fabrics,  Dr Cronje, a lecturer in the UFS’s Department of Consumer Science, and Dr Seiphetlheng from the Serowe College of Education in Botswana,  provided major new information with the thesis, Anolyte as an alternative bleach for cotton fabrics. This information is essential when considering the application of catholytes and anolytes in the textile industry.

Electrochemically-activated water divides water in catholytes and anolytes. The anolyte part is used as a disinfectant and bleach. It is not really suitable for domestic use, as it can cause colour loss in coloured textile products. However, it can be used in the hospitality industry where white sheets, towels, etc., are used and washed on a regular basis.

The catholyte part of the water has properties similar to washing powder. It can also be used in the textile industry as washing liquid.

According to Prof Hester Steyn, Head of the Department of Consumer Science and supervisor of all three PhD candidates, this electrochemically-activated water is also very eco-friendly. “It has a short shelf life. If the electrochemically-activated water isn’t utilised, it returns to normal water that wouldn’t harm the environment. No water is therefore lost, and no waste products are released that would contaminate the environment,” she says.

Dr Van der Merwe’s research focused on Degumming Gonometa postica cocoons using environmentally conscious methods. A lecturer in the Department of Consumer Science, she demonstrated that simple and environmentally-friendly methods can be used with great success to procure wild silk from the cocoons of the Gonometa postica worms living in the camel thorn trees found in the Northern Cape and Namibia.
