Description
Summary:Macro- and micromorphologic study of two milkcaps from Fazao Malfakassa National Park of Togo is supported by molecular phylogenetic analysis of ITS sequences obtained by the extraction of ribosomal DNA of each sample. This has led to the description of two new Lactifluus species: L. fazaoensis in L . subg. Edules and L. sudanicus in L . subg. Lactifluus . The two newly proposed taxa are compared with other related African species. Lactifluus fazaoensis is closely related to L . aureifolius and L . edulis , but is characterized by the concave to infundibuliform pileus, with dry, smooth and orange to greyish orange pellis and the distant, pale yellow to pale orange lamellae. Microscopically, it shows a character that has not up to now been as distinctly observed in Lactifluus : pleurocystidia and mainly cheilocystidia are tortuous to very irregularly branched and commonly diverticulate. Lactifluus sudanicus is morphologically recognizable by its convex to plano-convex, slightly depressed pileus, with dry, tomentose, slightly pruinose and pale orange to yellowish pellis. It is closely related to L. longisporus , L. flammans and L. volemoides . Microscopically, it presents lampropalisadic pileipellis and stipitipellis, with elements of suprapellis very high and close to L. medusae . Its basidiospores are ellipsoid with irregular amyloid warts ornamentation up to 1 μm, partially connected. The combination of these features does not match any of the species phylogenetically and morphologically close.
