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.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
