Deutsch: Found these growing on litter in a small group in the Central Siberian Botanical Gardens under Quercus robur, Tilia sp., and Larix sibirica. A friend brought me a specimen from mixed (Betula pendula, Populus tremula) forest she’d found a week earlier several kilometers to the South-east, near Morozovo, a small settlement. I’m assuming these are S. imperialis based on spore size and on that it is the only species of Sowerbyella listed for our region. It is also included in the 2008 Red Book of Novosibirsk District as a rare, poorly studied species.
