Chaetocalathus and Crinipellis (Basidiomycota, Marasmiaceae) in tropical Africa: taxonomic and nomenclatural novelties

A monograph of Crinipellis and Chaetocalathus species growing in tropical Africa is in preparation. During studies of the original material and other specimens, some new taxa were recognized and are described in this paper: Chaetocalathus niduliformis var. bisporus, Crinipellis atrovinosa var. parvispora, C. goossensiae, C. minutuloides, C. kisanganensis, C. nsimalensis, and C. pseudopalmarum. Crinipellis mauritiensis is described as a nomen provisorum because of the absence of a macroscopic description and the presence of only very poor material. Type revisions of Chaetocalathus niduliformis and Lentinus minutulus caused some taxonomic and nomenclatural novelties that are published here. A new status is proposed for Crinipellis pseudostipitaria var. orientalis.
