The spores do not seem to be fully matured. At full matur- 
ity they will doubtless be brownish and somewhat larger than 
indicatedabove. A sterile Asterzua also occurs on some of the 
leaves. There is a specimen in the Ellis Herbarium labeled 
Lembosia tenella Lév., U. S. North Pacific Ex. Exped. 
C. Wright, 1853-56, that is evidently this species. Neither 
host nor locality is given and there is only a fragment of a 
leaf, but this is quite certainly Coccoloba. Lembosza tenella 
was described by Léveillé (Ann. Sci. Nat. III. 3: 58. 1845) 
on leaves of Myrtaceae from Tahiti. His description calls for 
a black radiating mycelium, forming round black spots 2-4 
mm. in diameter. This is evidently different from our plant, 
where the mycelium is scanty and of such fine threads as to 
be invisible without high magnification. 
PERISPORIACEAE. 
Antennularia (?) tenuis sp. nov. 
Epiphyllous: mycelium widely effused, forming a thin 
olive- fe pellicle, mycelial hyphae much interwoven, deli- 
cate, thin-walled, subhyaline, about 4 » in diameter, fre- 
quently septate, the cells 12-18 y long, at intervals formin 
Torula-like chains of oval cells, 8-10 x 5-6 w; perithecia 
abundant, scattered, seated on the mycelium, black, globose, 
collapsing, of uniform rounded cells 8-10 in diameter, 
astomous, about 2004; asci elliptical, thin-walled, about 
80 x 25 #4; paraphyses abundant, delicate, thread-like, asco- 
spores inordinate, elliptical, obtuse, hyaline, 4-8 septate, the 
cells vertically divided, about 30 x 12 p.

The generic position of this interesting fungus is somewhat 
doubtful. Its spore-characters do not accord with those 
usually given for Axtennularia (Antennarza), but its bio- 
logical habit is the same and it seems unwise to multiply
