To M. J. Berkeley [March 1841]
12 Upper Gower St
My dear Sir
I have received your very obliging note & likewise your enclosure of to day—
I am delighted that you have found the edible fungus botanically curious— I shall be much interested in reading your paper—1 I trust you corrected the language of such extracts, as you thought worth taking— I did not think any were so—
I write now to inform you that I have probably led you into one small error— I stated that the Fungus grows on the Fagus antarctica,2 but I am almost certain that the F. betuloides is the common tree of Tierra del Fuego, & as this Fungus abounds every where it must grow on this latter species— it may (& I believe does) grow on the F. antarctica. You can correct this in proof, if you think it desirable—3
I saw my brother-in law—Hensleigh Wedgwood, your former schoolfellow & collegian,4 to day & he begged to be very kindly remembered to you.—
Believe me dear Sir | Your’s truly obliged | C. Darwin
Looks forward to the paper on CD’s edible fungus specimen from Tierra del Fuego [read 16 Mar 1841; Trans. Linn. Soc. Lond. 19 (1845): 37–43].
Sends a correction: Fagus betuloides, not F. antarctica, is the common tree of Tierra del Fuego.
