Mushroom
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.

Lithium-ion batteries research set to improve ordinary lives
2016-02-11

Description: Dr Lehlohonolo Koao  Tags: Dr Lehlohonolo Koao

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
