146 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
peduncles of 2 inches long, emitted from the side of the leaves. 
Your specimens were however too imperfect to be certain of its 
being the Blasia—however they agree very much with fructifying 
spec[imens] of the latter found by me—& I think I clearly observed 
the black male spots in yours—of which Hoffman. speaks in his 
little pocket Flora of Germany [31], where is a handsome figure. 
I have had the good fortune this year to find Sphaerocarpus 
terrestris in the utmost. perfection*—& a new Targionia which I 
have.called orbicularis besides the Targ. hypophylla, which in my 
little work is not recognised—has since been met with by me. 
Of all these you shall receive speclimens]. What I called Thelo- 
trema cinereum may possibly be Pyrenula enteroleuca for I am not 
acquainted with that genus—& this Lichen was altogether new to 
me—but I think it looks much like a Thelotrema. As to Evernia 
prunasirt being Borrera furfuracea you will convince yourself of 
Sprengel’s mistake when you get my Lichen—Both these are so 
well known to me from their being extremely common in Germany 
—that I am as certain of being in the right here, as concerning 
the next. Cetraria lacunosa aut nov—which has not the slightest 
resemblance with Nephroma papyracea—Sprengel’s opinion con- 
cerning what I called anes (Cenomyce) on the contrary | 
believe correct. 
The passage of Sprengel’s Letter to you, concerning the fungus 
I in a former letter to you had called Jsaria antheriformis—on 
a slight examination, at first excited my mirth a good deal because 
I thought it altogether impossible that that could be an hepatic 
moss. After I had however at the suggestion of your letter 
submitted this /saria antheriformis to a renewed examination by 
the compound Microscope—I have actually convinced myself that 
Sprengel nfust be in the right—altho’ I cannot conceive how it 
happens that an Hepatic should be generated in damp paper. 
There is a complete Thallus or Frons of a texture entirely similar 
to that of Sphaerocarpus for instance [a rough sketch is inserted 
here] forming a kind of net work in longitud{inal] meshes—& the 
antheriform fructification—assuredly bears a strong affinity to the 
Horn of an Anthoceros—so that I was affected with something like 
* When my little work was written I had not yet seen the ripe capsules, which I 
since found in plenty.
