Harrie Sipman
Henricus (Harrie) Johannes Maria Sipman (born 1945) is a retired Dutch lichenologist who specialised in tropical and subtropical lichens and authored or co-authored over 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010. Between 1990 and 1997 he edited and distributed the exsiccata ''Lichenotheca Latinoamericana a museo botanico Berolinensi edita''. Early life and education Sipman was born on 2 January 1945 in Sittard in the southern part of the Netherlands. As a schoolboy, he developed an interest in paleontology, collecting Cretaceous marine fossils from quarries in the hills surrounding his hometown. He later moved to Utrecht to study biology at Utrecht University. His first research project at university focused on paleontology, specifically the taxonomy of Cretaceous oysters. Through meticulous analysis, he demonstrated that morphological variations previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gyrotrema Papillatum
''Gyrotrema papillatum'' is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Harpidiaceae. It is known from a single collection in a lowland rainforest region of Costa Rica. Taxonomy ''Gyrotrema papillatum'' was described as new to science in 2011 by the German lichenologist Robert Lücking. The type specimen of this lichen was collected by the author in Costa Rica, in the Los Patos section of Corcovado National Park (Puntarenas Province). This location is part of the Osa Conservation Area on the Osa Peninsula, situated approximately southeast of San José and west-southwest of Golfito; there, in a lowland rainforest zone, at an elevation between , it was found growing on the bark of a partially shaded lower tree trunk. At the time of its original publication, the lichen was only known from the type locality. It species epithet alludes to the nature of its thallus (i.e., covered with papillae, which are small, conically rounded growths). ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphidaceae
The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark. Taxonomy Graphidaceae was originally proposed by French botanist Barthélemy Charles Joseph Dumortier in 1822 (as "Graphineae"). '' Graphis'', '' Opegrapha'', and '' Arthonia'' were included in the new family. In 2002, the German lichenologist Bettina Staiger revised the Graphidaceae in a monograph, proposing a new classification of genera that was widely accepted until molecular phylogenetic studies led to a further reorganization of the family. Two subfamilies are recognized in the Graphidaceae: *Fissurinoideae *Graphidoideae Subfamily Redonographoideae, proposed by Lücking and colleagues in 2013, has since been promoted to familial status (as the monogeneric family Redonographaceae).
