Aureoboletus moravicus, commonly known as the tawny bolete, is a species of bolete fungus in the family Boletaceae that is found in Europe. It is an uncommon bolete of unknown edibility that appears as a vulnerable species on some European Red Lists, and is considered critically endangered in the Czech Republic. Preferred habitats include parklands, near oak trees.
Originally described as Boletus moravicus by Václav Vacek in 1946, it was transferred to the genus Aureoboletus by Wolfgang Klofac in 2010.
Aureoboletus moravicus is confined to warmâÂÂtemperate deciduous woodlands on volcanic (andesitic) substrates with very acidic to mildly acidic soils (pH 3.9âÂÂ6.3), frequently underlaid by [loess deposits. In Slovakia, surveys have uncovered populations in the à  tiavnica Mountains and Kremnica Mountains as well as the basin, at elevations between 210 and 518 m above sea level. These sites are characterised by xerophilous oakâÂÂdominated standsâÂÂprincipally Quercus cerris, Q. petraea and Q. roburâÂÂoften mixed with hornbeam (Carpinus betulus) and occasionally beech (Fagus sylvatica).
Across Europe, A. moravicus is only known from scattered localities in central and southern temperate regions. It is redâÂÂlisted or legally protected in several countries (for example Slovakia, the Czech Republic, Denmark, Bulgaria, Switzerland, Croatia and Austria) owing to its rarity and narrow ecological requirements. Fruiting bodies appear singly or in small groups from July to October, typically on southâÂÂfacing or southâÂÂwestâÂÂfacing slopes in thermophilous (warm-loving) forest communities.
