Elaphomyces (‘deer truffles’) is a genus of hypogeous fungi in the family Elaphomycetaceae. The widespread genus contains 25 truffle-like species. Elaphomyces is one of the most important ectomycorrhizal fungal genera in temperate and subarctic forest ecosystems.{{Cite journal|last=Paz|first=A.|last2=Bellanger|first2=J.-M.|last3=Lavoise|first3=C.|last4=Molia|first4=A.|last5=Ławrynowicz|first5=M.|last6=Larsson|first6=E.|last7=Ibarguren|first7=I.O.|last8=Jeppson|first8=M.|last9=Læssøe|first9=T.|date=2017-06-30|title=The genus Elaphomyces (Ascomycota, Eurotiales): a ribosomal DNA-based phylogeny and revised systematics of European 'deer truffles'|journal=Persoonia|volume=38|issue=1|pages=197–239|doi=10.3767/003158517x697309|pmid=29151633|pmc=5645184}} E. asperulus, E. granulatus, and E. muricatus were found to accumulate arsenic (12–660 mg/kg in dry mass); the composition of organoarsenicals is very unusual, with methylarsonic acid and trimethylarsine oxide as major As compounds.{{Cite journal|last=Braeuer|first=Simone|last2=Borovička|first2=Jan|last3=Goessler|first3=Walter|date=2018-02-12|title=A unique arsenic speciation profile in Elaphomyces spp. ("deer truffles")—trimethylarsine oxide and methylarsonous acid as significant arsenic compounds|journal=Analytical and Bioanalytical Chemistry|volume=410|issue=9|language=en|pages=2283–2290|doi=10.1007/s00216-018-0903-3|pmid=29430602|pmc=5849658|issn=1618-2642}}
