Károly Kalchbrenner was a Hungarian mycologist. He trained in theology early in life and became a priest in Spišské Vlachy, north-eastern Slovakia. His contributions include the publication of 60 papers and description of more than 400 fungi from Europe, Asia, Australia and South America. He wrote and illustrated the Icones Selectae Hymenomycetum Hungariae. Among those he later collaborated with are Ferdinand von Mueller in Victoria, Australia, John Medley Wood in South Africa, Mordecai Cubitt Cooke in England and Felix von Thümen in Austria. He was elected a full member of the Hungarian Academy of Sciences, and a corresponding member of the Linnean Society of New South Wales.
Bothia is a fungal genus in the family Boletaceae. A monotypic genus, it contains the single species Bothia castanella, a bolete mushroom first described scientifically in 1900 from collections made in New Jersey. Found in the eastern United States, Costa Rica, China, and Taiwan, it grows in a mycorrhizal association with oak trees. Its fruit body is chestnut brown, the cap is smooth and dry, and the underside of the cap has radially elongated tubes. The spore deposit is yellow-brown. The edibility of the mushroom is unknown. Historically, its unique combination of morphological features resulted in the transfer of B. castanella to six different Boletaceae genera. Molecular phylogenetic analysis, published in 2007, demonstrated that the species was genetically unique enough to warrant placement in its own genus.
Psiloboletinus is a fungal genus in the family Suillaceae. This is a monotypic genus, containing the single species Psiloboletinus lariceti, first described by mycologist Rolf Singer in 1938 as a species of Phylloporus. Alexander H. Smith disagreed with Singer's generic concept, concluding "No matter what disposition of the type species of Psiloboletinus is eventually made, it is evident that there are no clearly distinctive characters on which to recognize the genus on the basis of Singer's descriptions."
