Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

A rare to very rare species red-listed in several European countries, and recognized as rare in the USA.


Geographic range

EUROPE: Estonia, France, Germany, Hungary, Italy, Spain, Sweden, UK. NORTH AMERICA: Canada (Nova Scotia), USA (Idaho, Michigan, North Carolina, Ohio, Oregon, Tennessee). Altitude: generally a lowland species, but with records up to 1400 m.


Population and Trends

Because trained dogs can find hypogeous fungi more easily than humans, estimates of abundance of all hypogeous species tend to be higher in Mediterranean countries where there is a tradition of using such animals. Described by ŁAWRYNOWICZ (2006) as rare in Europe. There have been no records of this species in the UK since 1952. In Hungary, it is listed as critically endangered (SILLER, VASAS, PÁL-FÁM, BRATEK, ZAGYVA, & FODOR, 2005) and is legally protected. It has been red-listed as declining in Poland, near threatened in Finland, rare in Denmark and Norway, vulnerable in Sweden, and as threatened because of extreme rarity in Germany. The species has been assessed as rare (category B, predisturbance surveys not practical) in Oregon, with the only record linked to the territory of the highly endangered northern spotted owl, and has been included in a list of species to be protected (albeit as a vascular plant) in the state’s Landowner Incentive Programme. Using IUCN Categories and criteria, MINTER (2007) assessed the conservation status of this species globally as Vulnerable.

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: a disturbed forest soil surface is often indicative of the presence of Elaphomyces, and this species has been found in the USA associated with scratchings made by deer. Species of Elaphomyces typically occur at the interface between the organic soil above and the mineral soil below. Some, including the present species, may also be mycorrhizal (BARROETAVEÑA, RAJCHENBERG & CÁZARES, 2005) thereby playing an important rôle in forest health. In England, E. anthracinus has been found at or up to 8 cm below the surface in various soils including clay, black humus and black burnt soil. Soils have varied in acidity from pH 5.7 to pH 7. Aspects have included north facing, ridge tops and flat areas. The species has been observed in February, March, April, May, June, August, September, October and November. Elaphomyces aculeatus is occasionally parasitized by Cordyceps agariciformis (= Elaphocordyceps capitata). Parasitism of the Elaphomycetaceae by members of that genus is common; the often brightly coloured fruitbodies of Cordyceps above ground can help in the finding of associated Elaphomyces underground. There has been speculation that the cosmopolitan mycorrhizal fungus Cenococcum geophilum Fr. is the anamorph of E. anthracinus, but molecular studies have not been able to confirm this (LOBUGLIO, 1990). Associated plants: Corylus avellana; Fagus sylvatica; Fagus sp.; Picea abies; Pinus ponderosa; Pinus sp.; Tsuga sp. Other associated organisms: Cervidae; Cordyceps agariciformis (= Elaphocordyceps capitata). Other substrata: soil.


Threats

Some species of Elaphomyces accumulate high levels of radioactivity following nuclear pollution, and E. anthracinus seems likely to be similarly affected.
