Cladonia Alpina
''Cladonia alpina'' (Swedish: ''Gaffelbägarlav'') is a species of fruticose lichen that is in the family Cladoniaceae. It has been found in Japan, Norway, and the United Kingdom. Molecular phylogenetic analysis indicates that ''Cladonia alpina'' is a member of the Erythrocarpae: Subglaucescentes clade, a group of species including '' C. floerkeana'', '' C. macilenta'' and '' C. polydactyla''. Although the presence of porphyrilic acid has been claimed to be diagnostic for this species, some non-European collections lack this substance. Description ''Cladonia alpina'' is similar to ''Cladonia macilenta'' in appearance, but has taller podetia measuring up to in height, usually bifurcate or sparingly dichotomously branched in the upper part. Podetia are partially or sorediate throughout, or more or less corticate with soredia only towards and at the tips; the soredia are to somewhat granular. Squamules at the base of the podetia are 1–2 mm long, and ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yasuhiko Asahina
Yasuhiko Asahina (朝比奈泰彦 ''Asahina Yasuhiko''; April 16, 1881 – June 30, 1975) was a Japanese chemist and lichenologist. Early life During his childhood, Asahina developed an interest in plants. In 1902, he enrolled in the School of Pharmacy at Tokyo Imperial University, from which he graduated in 1905. Asahina stayed at the university to research the chemical principles of Chinese traditional medicine under Junichiro Shimoyama. His first paper on styracitol isolation from ''Styrax obassia'' was published in 1907. In 1909, Asahina travelled to Zurich to study phytochemistry under Richard Willstätter. He continued his research on chlorophyll until 1912, when he moved to Berlin. He spent three months in Germany working in the laboratory of Professor Emil Fischer on a styracitol experiment.Shibata, S. (2000).

Soredia
Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria or green algae. These can be either scattered diffusely across the surface of the lichen's thallus Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms wer ..., or produced in localized structures called soralia. Fungal hyphae make up the basic body structure of lichen. The soredia are released through openings in the upper cortex of the lichen structure. After their release, the soredia disperse to establish the lichen in a new location.
