Catathelasma imperiale, also known as Catathelasma imperialis,

IUCN Red List of Threatened Species.[1]

Taxonomy

Catathelasma imperiale was first described from Sweden in 1845 by Norwegian botanist Nicolai Lund as Agaricus imperialis, but this name is

mycologist Petter Adolf Karsten in 1879. In 1922 the Austrian botanist Günther Beck von Mannagetta und Lerchenau created the new genus Biannularia for this species, making it Biannularia imperialis. In 1940, Singer transferred it to the existing genus Catathelasma, considering the two genera to be synonymous.[6] Recent DNA research confirms this synonymy.[5]

The epithet "imperiale", meaning "imperial" refers to the (at times) imposing size of the fruit bodies.

Description

Fruit bodies are

clamp connections.[5]

Habitat and distribution

Catathelasma imperiale is an

ectomycorrhizal species, forming an association with conifers, particularly spruce.[5][7]
Originally described from Scandinavia, it has been recorded from most northern countries in continental Europe as far south as Italy. It has also been recorded in Asia from China, Korea, and Japan.[1] Records from North America are uncertain, since DNA sequencing of specimens determined as "C. imperiale" have (to date) proven to belong to C. evanescens or C. ventricosum.[5]

Conservation

The species is legally protected in Poland and is included in the Red Lists of 15 European countries. It is considered declining everywhere due to forest

Catathelasma imperiale is edible and collected for food in China, Bhutan, Ukraine, and Russia.[8][9] In Ukraine, it is known as korban, or the Hutsul mushroom, because it is common among the Hutsuls who are said to be experts at finding it. In the Carpathian mountains, it grows in coniferous and spruce forests at an altitude of 400 – 1000 m. In the Hutsul culinary tradition, it is often dried, powdered, and used as a spice in gravies, kulish, stews, and bakes. It is also used as a meat substitute in patties during Lent.[10]
