Edible fungi consumed by the Lamba and Bemba people of Haut-Katanga (DR Congo)

The objective of this work is to establish a list of species of edible fungi consumed by the Lamba and Bemba people of Haut-Katanga (DR Congo). This study contributes to the valorization of edible fungi gathered in the miombo woodlands of Haut-Katanga. A survey was conducted among Lamba and Bemba people of the peri-urban area of Lubumbashi. The first author conducted structured and semi-structured surveys among 331 people, mostly women aged 30-50. The results show the existence of thirty-eight edible species belonging to 9 genera and 8 families. The majority is ectomycorrhizal (66%) followed by Termitomyces (21%), while only a few are saprotrophic (13%). Lamba and Bemba people consume all taxa. Twenty-three local names have been recorded in their respective languages, i.e., Kilamba and Kibemba, two closely related Bantu languages belonging to the family’s Eastern clade. The Lamba and Bemba do not consume species of the genera Russula (Russulaceae) and Boletus (Boletaceae). We succeeded in reconstructing the conceptualization underlying the creation of several Kibemba and Kilamba mushroom names. Popular and scientific taxonomies rarely overlap: one and the same species may have different names in Kilamba and Kibemba, while one and the same name in Kilamba and/or Kibemba is often used for several congeneric species. Species considered toxic and not consumed do not have a Kilamba or Kibemba name of their own. Instead, they are collectively referred to by a term fyana fya bene, literally meaning “big (dangerous) children of them” and signaling that local consumers reject those species

Lentinus cystidiatus sp. nov. (Polyporaceae): an African lentinoid fungus with an unusual combination of both skeleto-ligative hyphae and pleurocystidia

Background and aims – Lentinus species are a major component of the agaricoid flora of tropical Africa where fifteen species have been documented with few studies in Cameroon. This work aims to contribute to the taxonomy of the genus Lentinus by describing a putative new species collected in south-western Cameroon. Methods – A unique lentinoid fungi specimen collected in Korup National Park in the South-West region of Cameroon and preserved in the Edinburgh herbarium (E) was examined macro- and microscopically following classical mycological description methods. Key results – The sp ecimen examined possesses squamules on the pileus and stipe surface, no annulus, furcated branching dichotomous lamellae, oblong-cylindrical basidispores, basidia generally bearing four sterigmata (sometimes two or one) reaching 5 μm long, skeleto-ligative hyphae and pleurocystidia. The simultaneous presence of both pleurocystidia and skeleto-ligative hyphae has never been encountered in the genus Lentinus . Due to this unusual combination and other specific features of this specimen, it is considered as a representative of a new species within the genus Lentinus . Discussion – Lentinus cystidiatus exhibits some similar characteristics with Lentinus squarrosulus that possesses squamules on the pileus and stipe surface and mostly with species of the sub-genus Lentinus section Dicholamellatae that are characterized by furcated lamellae. As skeleto-ligative hyphae is characteristic of the sub-genus Lentinus and pleurocystidia characteristic of sub-genus Panus, the simultaneous presence of elements brings into question the taxonomic position of this new species and the systematics of the genus Lentinus in general. Conclusions – The existence of this new species in Cameroon opens a door on the necessity of a taxonomic revision of the genus Lentinus and allied genera

Two rare Phallales recorded from São Tomé

Two little known species of Phallales, Mutinus zenkeri and Blumenavia angolensis, were collected on the volcanic island of São Tomé in the Gulf of Guinea, Africa. Descriptions and in situ photographs are provided for both species. Inferences of their phylogenetic relationships within the Phallales are provided based on partial nucLSU rDNA sequence data
