To Miles Joseph Berkeley [26 November 1840]
is the Fagus oblique.— So that we have probably two species, & closely allied species of Fungus, growing on two species of Fagus, at the distance of 1000(?) miles.—1 The Fungus of Tierra del Fuego grow on the Fagus Antarcticus.—2 Bertero says the natives of Chile call the Fungus “dignénes”.— Bertero’s [paper] or rather posthumous list of plants is in Silliman’s N. Am. Journal Vol. 23 p. 78.— I should be much obliged if at some future time, you would have the kindness to return me the rough papers.—3
I have the pleasure of remaining | Your’s truly obliged | Charles Darwin
Remarks that each of two species of Fagus separated by 1000 miles has a fungus that grows on it; the fungus species are probably closely allied.
