Biography
Dutch botanist Henricus Sipman is an expert on neotropical lichens. Sipman (known as Harrie) was born in Sittard, the Netherlands, and studied botany at Utrecht State University, gaining his PhD in 1983. In the 1970s he worked at Utrecht's Institute of Systematic Botany, particularly concentrating on lichenology and bryology. In particular he wrote papers on the lichen genera Cladonia and Stereocaulon, and on the Musci Anisothecium staphylinum, Campylopus and Ephemerum.
After a colleague returned from a field trip with collections of unidentified lichens from Colombia, Sipman turned his attentions to the lichen flora of that country. He published a revision of the lichen family Megalosporaceae in 1983, undertaking field studies in Brazil, Colombia, Costa Rica and Venezuela, and in New Guinea, Tasmania and New Zealand in preparation.
Since 1983 Sipman has been curator of the lichen herbarium at the Botanic Garden in Berlin. He has also been co-editor of the journal International Lichenological Newsletter (1987-1996) and of Tropical Bryology (1992-2000). Since 1993 he has been a member of the Flora Neotropica Commission and of the IAPT Committee for Fungi. Sipman has been actively involved in the Flora of the Guianas project, travelling to the area several times in the 1980s and 1990s to make collections to support the work. He also works on lichens from other regions of the world and is involved in a Mediterranean lichen flora. Many taxa are named after him.
