“…(1900: 338) and Scleroderma citrinum Pers. (1801: 153), gasteroid members of Boletales (Winner et al 2004). It would be a good chemotaxonomical character of Imleria if these pigments were found in the pileus of the rest of the species of this genus in the future.…”

The genus Imleria can be easily distinguished from other genera of Boletaceae by the combination of the following characters: a chestnut brown pileus and stipe, a cream to pale yellow hymenophore, a viscid pileal surface when moist, a cyanescent context and hymenophore on handling or exposure, an ixotrichodermal pileipellis and smooth spores. The monophyly of Imleria and the detection of four independent species were highly supported by phylogenetic analyses using 5 gene markers. The four species, including the previously recognized Im. badia, Im. obscurebrunnea, plus the newly discovered Im. parva and Im. subalpina, are fully documented with taxonomic descriptions and illustrations, and a key to the taxa is provided. Geographically, Im. badia is widely distributed in Europe, North America and probably in Far East Asia, yet there is some intraspecific divergence between specimens from Europe and North America caused probably by geographic isolation. Imleria subalpina and Im. obscurebrunnea might diverge from each other relatively recently with the uplifts of the eastern Himalayas and Hengduan Mountains. An epitype collected from Sweden was designated for Im. badia.

“…Subsequent regioselective elimination and allylic oxidation generated nidemone (42) in eight steps in 10 % overall yield. Recently, Snyder and co-workers [33] reported the first total synthesis of chalcitrin (45), a structurally distinct pulvinic acid dimer isolated from Calciporous piperatus [34] The acafarnane-type diterpenoid farnesin (53), which has a cis-fused tetracyclic structure, was isolated from the seeds of Acacia farnesiana by Sahu and co-workers in 1997. [35] Our group recently achieved its asymmetric total synthesis via photo-Nazarov cyclization to afford the cis-fused tetracyclic structure and an intramolecular aldol reaction to furnish the bicyclo-[3.2.1]octane (C-D ring) (Scheme 12).…”

Velíšek J., Cejpek K. (2011): Pigments of higher fungi -a review. Czech J. Food Sci., 29: 87-102.This review surveys the literature dealing with the structure of pigments produced by fungi of the phylum Basidiomycota and also covers their significant colourless precursors that are arranged according to their biochemical origin to the shikimate, polyketide and terpenoid derived compounds. The main groups of pigments and their leucoforms include simple benzoquinones, terphenylquinones, pulvinic acids, and derived products, anthraquinones, terpenoid quinones, benzotropolones, compounds of fatty acid origin and nitrogen-containing pigments (betalains and other alkaloids). Out of three orders proposed, the concern is only focused on the orders Agaricales and Boletales and the taxonomic groups (incertae sedis) Cantharellales, Hymenochaetales, Polyporales, Russulales, and Telephorales that cover most of the so called higher fungi often referred to as mushrooms. Included are only the European species that have generated scientific interest due to their attractive colours, taxonomic importance and distinct biological activity.
