Dear Sir,

I wrote you while your last letter was
on the way to me - but thi [this] was in the mail
before I could get yours, as it came by Hartford,
Northhampton, etc. Fearing you may do, what you
say you do not often, answer my letter soon, I wish
now to make some inquiries about the last. You
had written me the names of some plants in your
preceding letter, which you have mentioned in your
last. In two cases, your letters do not agree, or else I
have mistaken. As I am willing it should be the latter,
I may inquuire. Of the Fungi, No. 30, on apples, is
it a Puccinia or an Aecidium? Which species of [Achasins',?]
[Lacanora?], is L. petrophila, if I read it right; it is
my No. 33.

In [Prince's?] Box, I sent a Laminaria, which
you call L. esculenta. If I have sent but one, it was before
named, L. digitata [added: Lam.]. [?] digitatus, Lin. In the same
box, Ulva? "U. crispa? when did it come?" If I know what
you mean, it is a dark green membranous plant  _ if so.
it grows or is found on the stones in a brook near me, in
great abundance. "No. 5. Thelephora conyophyllea?" It is a perfect
funnel with a long neck, & [?] with the utmost regularity.
I [flatted?] it to preserve it. It grows on the ground on a
[rock?] soil thin, in woods.

I believe I can send you more G. villia in fruit. No. 10.
Porina, is it not P. [?] or a var. Grows on rocks, quite
large as you see. I shall be glad to hear of these, soon
as you can tell them.

There is no Chora fragilis in Boston or Ph. but there is
Conlinia fragilis, I know not whose Chora, it is, or is
[crossed out: Chlora flexilis] it C. flexilis - for it can not be C. fragilis, &
