Boletus Regius
''Butyriboletus regius'' (formerly ''Boletus regius''), commonly known as the royal bolete or red-capped butter bolete, is a basidiomycete fungus of the genus '' Boletus'' found in China and Europe. ''B. regius'' has a pink cap, yellow flesh, and a reticulate pattern on the stem. Harry D. Thiers described a similar mushroom from California as ''B. regius'', though it is not the same species. ''B. regius'' in Europe does not stain when exposed to air, or stains weakly, but the California species stains blue. Both European and California species are considered choice edibles. Taxonomy The species was first described and illustrated by Julius Vincenz von Krombholz in 1832. Common names for the mushroom include the red-capped butter bolete and the royal bolete. ''Butyriboletus regius'' was formerly classified as a member of the section ''Appendiculati'' of the genus ''Boletus''. Molecular analysis demonstrated that this and related "butter bolete" species, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julius Vincenz Von Krombholz
Julius Vincenz von Krombholz (19 December 1782 – 1 November 1843) was a physician and mycologist born in Oberpolitz (today Horní Police, Czech Republic), northern Bohemia. He studied medicine at the University of Prague, receiving his doctorate in 1814. In 1828 he was appointed professor of special pathology and therapy. At Prague, he used his influence to help the penniless August Carl Joseph Corda (1809–1849) get admitted to the university. In 1831 he was named rector of the university. Contributions In addition to his career in medicine, Krombholz had a keen interest in mycology. He performed numerous experiments involving the toxicity of mushrooms. He is known fo''Naturgetreue Abbildungen und Beschreibungen der essbaren, schädlichen und verdächtigen Schwämme''(1831–1846), a publication on mushrooms that was based on his own observations. It is acclaimed for its true-to-nature pictures and its descriptions of edible, harmful and suspect mushrooms. Krombholz died bef ...

Butyriboletus
''Butyriboletus'' is a genus of fungi in the family Boletaceae. The genus was circumscribed in 2014 by mycologists David Arora and Jonathan L. Frank to accommodate "butter bolete" species that were shown by molecular phylogenetics, molecular analysis to be phylogenetically distinct from ''Boletus''. ''Butyriboletus'' contains 24 ectomycorrhizal species found in Asia, Europe, North America and north Africa. The group had earlier been classified as the Section (botany), section ''Appendiculati'' within the large genus ''Boletus''. They were given the common name "butter boletes" as the color of their stalk, trama (mycology), flesh and pores was similar to that of butter. Molecular phylogenetics, Genetic analysis published in 2013 shows that these species are part of a ''regius'' clade (named for ''Boletus regius, B. regius''), distinct from the core group of the type species ''Boletus edulis, B. edulis'' and relatives within the Boletineae. The narrowing of ''Boletus'' to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
