Studies in Coprinus III — Coprinus section Veliformes. Subdivision and revision of subsection Nivei emend

Coprinus section Veliformes is defined and delimited to comprise four subsections: subsection Micacei, subsection Domestici, subsection Nivei, and subsection Narcotici, subsection nov. A key to the subsections is given. Subsection Nivei is emended, including also most taxa of subsection Flocculosi Citerin. A key is given to all species known from the Netherlands, or to be expected in the Netherlands on account of records from neighbouring countries. Three new species are described, viz. Coprinus nemoralis, C. idae and C. pseudoniveus. A neotype has been selected for Coprinus poliomallus Romagn. The following species are fully described: C. bellulus, C. candidates, C. cardiasporus, C. coniophorus, C. cordisporus, C. cortinatus, C. cothurnatus, C. ephemeroides, C. idae, C. iocularis, C. nemoralis, C. niveus, C. pachyspermus, C. patouillardii, C. pseudoniveus, C. pilosotomentosus, C. poliomallus, C. pseudocortinatus, C. ramosocystidiatus and C. utrifer

Additional studies in Coprinus subsection Glabri

First Coprinus lilatinctus, belonging to subsect. Glabri, is described as new. Secondly, nomenclatural reasons are given for Coprinus nudiceps P.D. Orton to be replaced by the older name C. schroeteri P. Karst. Type studies of both taxa are given and their synonymy is discussed. To facilitate identification an updated key is given for the species in subsect. Glabri

Type studies in Coprinus subsection Lanatuli

As a prelude to a monograph of the genus Coprinus, types were studied of a number of species said to belong to Coprinus subsection Lanatuli (Coprinus alnivorus. C. alutaceivelatus, C. ammophilae, C. arachnoideus, C. asterophoroides, C. brunneistragulatus, C. bubalinus, C. citrinovelatus, C. colosseus, C. jonesii, C. lagopides, C. marcidus, C. pachydermus, C. palmeranus, C. roseistipitatus, C. scobicola, C. spadiceisporus, C. sylvicola, C. tectisporus, C. undulatus and C. xerophilus). As a result Coprinus alnivorus and C. lagopides are transferred to subsection Alachuani

A new Coprinus from Papua New Guinea sporulating in pure culture

From Papua New Guinea a new Coprinus is described, which forms basidiocarps and basidiospores in pure culture. It was isolated from material collected on two collecting trips to the area, in 1992 and 1995
