摘   要：

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.
