Assessment Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

This species is uncommon to rare through much of its range, being seen sporadically. In various national red lists in Europe, it is listed as rare to critically endangered.


Geographic range

EUROPE: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Germany, Greece, Hungary, Italy, Lithuania, Luxembourg, Poland, Romania, Russia (Moscow oblast), Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, UK, Ukraine. Probably more widespread in Europe and possibly also occurring in Asia. A record of Choiromyces, exists from Antarctica. The fungus was isolated from a cryoconite hole in the Canada Glacier in the McMurdo Dry Valley region, and was identified using small subunit (16S/18S) rDNA amplification, cloning and sequencing (the sequence was closest to another sequence, in a gene library, already identified as C. meandriformis). The authors speculated that the cryoconite hole was colonized from adjacent lake ice and microbial mat environments (CHRISTNER, KVITKO & REEVES, 2003). This record has not been included in the geographical distribution above.


Population and Trends

Because trained dogs can find hypogeous fungi more easily than humans, estimates of abundance of all hypogeous species in Europe tend to be higher in Mediterranean countries where there is a tradition of using such animals. PEGLER, SPOONER & YOUNG (1993) described C. meandriformis as a “relatively common species which is widespread in England”, while MONTECCHI & SARASINI (2000) regarded the species as “almost widespread” throughout Europe. The species is red-listed as endangered in Denmark and Lithuania, rare in Bulgaria and Poland and as critically endangered for Germany in general and Nordrhein-Westfalen in particular. It was, however, removed from the Swedish red list. Using IUCN Categories and criteria, MINTER (2007) evaluated the conservation status of this species as Near Threatened (Data Deficient).

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. Choiromyces meandriformis is usually associated with deciduous trees and, at least sometimes, with slightly acid soil. It is often found just at ground level or half-buried or unearthed by heavy rainfall. The species has been observed in June, July, August, September, October and November. Associated plants: Acer pseudoplatanus; Aesculus sp.; Betula sp.; Cedrus atlantica var. glauca; Cistus ladanifer; Coniferae indet.; Fagus sylvatica; Fagus sp.; Fraxinus excelsior; Ilex aquifolium; Picea abies; Pinus sp.; Poaceae gen.indet.; Populus sp.; Quercus robur; Quercus sp.; Salix sp.; Sequoia sp.; Tilia cordata; Tilia sp. Other substrata: soil.


Threats

Choiromyces meandriformis, considered by some to be edible, is itself of little or no value as human food, and there are some suggestions from Italy and Spain that it may cause stomach upsets or even be toxic (MONTECCHI & SARASINI, 2000). It is, however, sometimes marketed fraudulently as Tuber magnatum Pico. GREGORI (2003) reported that, in northern Italy, this species among others was readily detected in several locations by trained sniffer dogs, and its presence was regarded as indicative of an area suitable for development in commercial truffle production.
