A first checklist of macrofungi for South Africa

A description of two novel Psilocybe species from southern Africa and some notes on African traditional hallucinogenic mushroom use

Two new Psilocybe species (Hymenogastraceae), P. ingeli and P. maluti, are described from southern Africa. Morphology and phylogeny were used to separate the two novel fungi from their closest relatives in the genus. Psilocybe ingeli was found fruiting on bovine manure-enriched grasslands in the Kwa-Zulu Natal Province of South Africa and differs from its closest relative P. keralensis and others in the internal transcribed spacer ITS1-5.8S-ITS2, partial 28S nuc rDNA, and translation elongation factor 1-alpha regions, distribution, and having larger basidiospores. Similarly, P. maluti was collected from the Free State Province of South Africa and observed in the Kingdom of Lesotho, growing on bovine manure. A secotioid pileus, geographic distribution, and differences in the same DNA regions distinguish P. maluti from its closest relative P. chuxiongensis. Furthermore, the spore dispersal and traditional, spiritualistic use of P. maluti are discussed here.

Global species diversity and distribution of the psychedelic fungal genus Panaeolus

Psychedelic fungi have received considerable attention recently due to their promising treatment potential of several psychiatric disorders and medical conditions, both in clinical settings but also as a nutraceutical. Besides research, a growing number of companies are developing capacity to conduct research and clinical trials where these fungi and their products can be used, and to provide these fungi to the public market that are rapidly becoming legal across the world. Whereas Psilocybe species are better known as psychedelic fungi, species in Panaeolus are also reputed to contain the psychedelic compound psilocybin and used recreationally. For the novice, there is no contemporary scientific summary of all the species in this genus that are known to be psychedelic, compared to those that are not. The global distribution and species diversity of these brown to white, often inconspicuous mushrooms are also not summarised, nor is it known to what extent DNA sequence data that are needed for identification have been generated for all of the species in this genus. However, psychedelic Panaeolus species are used and moved across the world. This lack of data makes it difficult to regulate bioexploitation and apply law enforcement of these fungi and the compounds they contain, especially seen in the light of the rapid development of the related markets. The aim of this review is to summarise current scientific data and knowledge on the species biodiversity, geographical distribution, extent of sequence data for identification purposes, and the psychedelic potential of species, based on published results. The review revealed where species are mostly known from, while also indicating areas seriously lacking such biodiversity data. A significant degree of study across the world is still needed to confirm which of these species are truly psychedelic and exactly what compounds they can produce.

Hericium ophelieae sp. nov., a novel species of Hericium (Basidiomycota: Russulales, Hericiaceae) from the Southern Afrotemperate forests of South Africa

A novel species of Hericium was recently collected in the Afrotemperate forests (Knysna - Amatole region) of Southern Africa. The novel species shares many similar, dentate features common to other species in Hericium, and its basidiome first appears stark white and yellows with age. However, the substrate choice and gloeocystidia and basidiospore sizes of the specimens collected were distinct from other Hericium species. This was confirmed by sequencing the ITS and 28S genetic markers, respectively. The novel species is described as Hericium ophelieae sp. nov. and appears unique as it grows on hardwoods indigenous to Southern Africa. The species has larger basidiospores and wider gloeocystidia compared to its closest relative. H. ophelieae sp. nov. is the first endemic species of the medicinal mushroom genus Hericium to be described from Southern Africa, and the second to be described from Africa, after its closest relative, H. bembedjaense, which was isolated in Cameroon. Although this is the first Hericium to be described from the Southern African region, there are likely others to be discovered, and this study highlights the need for further research into the fungal diversity of Afrotemperate environments.

A compendium of macrofungi of Pakistan by ecoregions

Macrofungi form fruiting bodies that can be detected with the naked eye in the field and handled by hand. They mostly consist of basidiomycetes, but also include some ascomycetes. Mycology in Pakistan is still in its infancy, but there have been many historical reports and checklists of macrofungi occurrence from its 15 ecoregions, which range from Himalayan alpine grasslands and subtropical pine forests to deserts and xeric shrublands. In this work, we searched and reviewed the historical literature and the GenBank database for compiling a comprehensive list of macrofungi reported from Pakistan to date. We recorded 1,293 species belonging to 411 genera, 115 families and 24 orders. These occurrences were updated taxonomically following the classification system currently proposed in the Index Fungorum website. The highest represented order by taxon number is Agaricales (47%) with 31 families, 146 genera and 602 species, followed by Polyporales (11%), Russulales (9%) and Pezizales (8%). Genera occurrence reported therein are presented for each ecoregion to the best of our ability given the data. We also discussed the currently known macrofungi diversity between different ecoregions in Pakistan. Overall, this work should serve as a solid foundation for the inclusion of Pakistan macrofungi in global biodiversity and conservation studies.

Mushroom Nutrition as Preventative Healthcare in Sub-Saharan Africa

The defining characteristics of the traditional Sub-Saharan Africa (SSA) cuisine have been the richness in indigenous foods and ingredients, herbs and spices, fermented foods and beverages, and healthy and whole ingredients used. It is crucial to safeguard the recognized benefits of mainstream traditional foods and ingredients, which gradually eroded in the last decades. Notwithstanding poverty, chronic hunger, malnutrition, and undernourishment in the region, traditional eating habits have been related to positive health outcomes and sustainability. The research prevailed dealing with food availability and access rather than the health, nutrition, and diet quality dimensions of food security based on what people consume per country and on the missing data related to nutrient composition of indigenous foods. As countries become more economically developed, they shift to “modern” occidental foods rich in saturated fats, salt, sugar, fizzy beverages, and sweeteners. As a result, there are increased incidences of previously unreported ailments due to an unbalanced diet. Protein-rich foods in dietary guidelines enhance only those of animal or plant sources, while rich protein sources such as mushrooms have been absent in these charts, even in developed countries. This article considers the valorization of traditional African foodstuffs and ingredients, enhancing the importance of establishing food-based dietary guidelines per country. The crux of this review highlights the potential of mushrooms, namely some underutilized in the SSA, which is the continent’s little exploited gold mine as one of the greatest untapped resources for feeding and providing income for Africa’s growing population, which could play a role in shielding Sub-Saharan Africans against the side effects of an unhealthy stylish diet.

Poroid Hymenochaetaceae associated with trees showing wood-rot symptoms in the Garden Route National Park of South Africa

Poroid Hymenochaetaceae associated with wood rots of trees in three timber-harvesting compartments of the Garden Route National Park (GRNP), South Africa, were investigated using multilocus phylogenetic analyses and morphology of the basidiomes. Results revealed the presence of 10 species belonging to five genera. Six of the species are known, but four are described as new. The known species include Fomitiporia capensis, Fuscoporia gilva, Sanghuangporus microcystideus, Tropicoporus tropicalis, Inonotus rickii, and Inonotus setuloso-croceus. The new species are described as Fomitiporia tsitsikamensis, Fulvifomes elaeodendri, Fuscoporia pulviniformis, and Phellinus guttiformis.
