Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

A widely distributed species nowhere described as common, and reported as rare or threatened in several parts of its range.


Geographic range

ASIA: Japan. CENTRAL AMERICA: Costa Rica. EUROPE: Austria, Belgium, Czech Republic, Denmark, France, Germany, Ireland, Italy, Lithuania, Netherlands, Poland, Romania, Russia (Moscow oblast), Slovenia, Spain, Sweden, UK. NORTH AMERICA: USA (Michigan, Oregon, Wisconsin). Altitudes up to 1600 m.


Population and Trends

Hydnotrya tulasnei has been red listed as critically endangered for Germany, as endangered for Nordrhein-Westfalen and as threatened for Mecklenburg-Vorpommerns. It appears on a list of extinct and endangered species of Lithuania, but its status on that list is said to be indeterminate. The species was given low priority for monitoring as a species of special concern in a list of fungi from the Owyhee Region (Idaho & Oregon, USA). It is listed as near threatened for Kyoto Prefecture, Japan.

Population Trend:


Habitat and Ecology

Hypogeous fungi make an important contribution to the dynamics of woodland and forest soils, through their mutualism with mammals resulting in digging and aeration. The species has been observed in May, June, July, August, September and October. Associated plants. Acer sp.; Alnus sp.; Betula sp.; Carpinus betulus; Castanea sativa; Fagus sylvatica; Fagus sp.; Ilex aquifolium; Larix sp.; Picea abies; Picea sp.; Pinus nigra; Pinus sp.; Quercus copeyensis; Q. glauca; Q. ilex; Q. oocarpa; Q. robur; Q. seemanii; Q. × turneri; Quercus sp.; Salix sp.; Tilia sp. Other associated organisms: Muscopsida; Rodentia; Sciurus vulgaris (eating ascomata). Other substrata: humus, soil.


Threats

Disturbance of forest ecosystems may be a threat.
