Johannes Hillmann
Johannes Hillmann (1881–1943) was a German teacher, botanist, and lichenologist. Hillman was born in Berlin in 1881. He became a teacher after studying natural sciences at the University of Berlin. Hillmann researched lichens from the period 1916 to 1943, contributing 36 publications on the subject. He is perhaps best known for his contributions to the families Parmeliaceae and Teloschistaceae, which were published in Gottlob Ludwig Rabenhorst's influential work ''Dr. L. Rabenhorst's Kryptogamen-Flora von Deutschland, Oesterreich und der Schweiz''. Hillman retired from teaching in 1939, and died in Berlin in 1943. His herbarium of specimens, located in Buckow, was destroyed during World War II. Four lichen species named after Hillman are '' Buellia hillmanii'' , '' Lecidea hillmannii'' , '' Micropeltella hillmanniana'' , and ''Propolis hillmanniana Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered fr ...

Botanist
Botany, also called plant science (or plant sciences), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (') meaning " pasture", "herbs" " grass", or "fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecidea Hillmannii
''Lecidea'' is a genus of crustose lichens with a carbon black ring or outer margin (exciple) around the fruiting body disc (apothecium), usually (or always) found growing on (saxicolous) or in ( endolithic) rock.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens that have such a black exciple are called lecideine, meaning "like ''Lecidea'', even if they are not in this genus. Members of the genus are commonly called disk lichens or tile lichens. Selected species According to the ''Dictionary of the Fungi'' (10th edition, 2008), the widespread genus contains an estimated 427 species. * ''Lecidea atrobrunnea'' * ''Lecidea hassei'' * ''Lecidea keimioeensis'' * ''Lecidea laboriosa'' * ''Lecidea lithophila ''Lecidea'' is a genus of crustose lichens with a carbon black ring or outer margin (exciple) around the fruiting body disc (apothecium), usually (or always) found growing on (saxicolous) or in ( endolithic) rock.Field Guide to Califor ...

Akademische Verlagsgesellschaft
The (AVG, AVg, Aka, AV; English: Academic publishing company) in Leipzig was an important German academic publisher, which was founded in 1906. The original Jewish owners of the publishing house and key employees were expropriated during the time of the Nazi regime, emigrated and founded new scientific publishing houses in other countries. The publishing house was then named . After World War II, in the German Democratic Republic (GDR/DDR) the Leipzig branch of the publishing house was transformed into in 1947 and 1951. This was dissolved in 1991 as a consequence of the German reunification. Between 1953 and 1983, another seeing itself as the legal successor of the original company existed in the Federal Republic of Germany (FRG/BRD) in Frankfurt am Main and Wiesbaden. Today, there are two German publishing houses claiming to stand in the tradition of the , AULA-Verlag and AKA-Verlag, although legally they are new and independent foundations.

Propolis Hillmanniana
Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the beehive. Propolis is used for small gaps (approximately or less), while gaps larger than the bee space (approximately ) are usually filled with burr comb. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures it becomes hard and brittle. When foraging, worker bees primarily harvest pollen and nectar, while also collecting water and plant resin necessary for the production of propolis. The chemical composition and nature of propolis depend on environmental conditions and harvested resources. Types Mixed types of propolis found in European countries with a moderate climate include two or more sources of plant resins (plant species) identified by compos ...

Buellia Hillmanii
''Buellia'' is a genus of mostly lichen-forming fungi in the family Caliciaceae. The fungi are usually part of a crustose lichen. In this case, the lichen species is given the same name as the fungus. But members may also grow as parasites on lichens (lichenicolous). The algae in the lichen (the photobiont partner) is always a member of the genus ''Trebouxia''. Lichens in the genus are commonly called disc lichens, or button lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The genus has a widespread distribution and contains about 450 species. Genetic studies indicate that the genus ''Amandinea'' and ''Buellia'' may be the same,Scheidegger, C. 2009. Amandinea Choisy ex Scheid. & H. Mayrhofer (1993). In: C. W. Smith, A. Aptroot, B. J.
