SPECIES OF CHRYSOSPLENIUM. 457 
under a lens is minutely downy. Sporidia minute, broadly 
segmentiform. 
More nearly allied to S. Hypoxylon than to S. polymorpha. 
The sporidia are smaller even than in the former of these 
species, and broader in proportion to their length. They are 
very much smaller than those of S. polymorpha, which may 
be distinguished from some allied forms, by its large sporidia. 
The size of the sporidia, within certain limits, is not, however, 
constant as I have shown in the case of S. pedunculata. The 
nearest species, perhaps, to that before us, is Spheria scru- 
posa, Fr. 
23. Lycogala Epidendrum, Fr. 
New Guinea. 
I take this opportunity of correcting the following notes to 
the Memoirs in a former number of this Journal. 
P. 139. No. 3 should be Lenzites applanata, Fr.—Host., n. 474. 
P. 149, It is probable that Polyporus elongatus is the same species with Pol. 
Flabellum, Montagne, n. s., from whom 1 have received specimens since the 
paper was printed, and, who observes that it is very variable. 
P. 154, line 1, for **ring-bracing," read * ring-bearing.” 
P. 156. Spheria micraspis is probably a Verrucaria, and perhaps, Verrucaria 
nitens, Fée. 
On two species of CRRYSOSPLENIUM, from extratropical South 
America. By W. J. HOOKER. 
(With two plates, Tas. XVI. XVII.) 
-In a collection of plants from Valdivia, sent to me by Mr. 
Bridges some years ago, is a plant, No. 781 of said collection, 
without fructification ; concerning the genus, or indeed the Nat. 
Order of which I was doubtful, till I received a nearly 
allied plant from my friend Dr. Lemann, from the late Mr. 
Lambert’s portion of Capt. King’s plants from the Straits of 
Magellan and adjacent countries, whose flowers clearly showed 
it to be a Chrysosplenium ; or at least, only differing from that 
genus in the insertion of the seeds, which is not confined to 
the base of the cell; and in the styles, which vary from two 
to three.
