The sporidia vary slightly in the two forms referred to this species.. In the one they are subeymbiform, as in 
the European form, and 4455 inch in length; in the other oblong, with the endochrome retracted to either end, 
and 3257 inch long. I can see no external difference, j l

mate semi-immersis, sporidiis oblongis curvulis. ; 
Has. On dead bark, Archer. 
Pale-scarlet. Stroma bursting out in linear patches. Perithecia half-immersed, ovate, papillate, pruinose. 
Sporidia len see inch long, oblong, slightly curved. 
5. Nectria Tasmanica (Berk.); cespitosa, rubra, stromate pallido, peritheciis ovatis, ostiolo papil- 
leeformi seepe e disco orbiculari oriundo, sporidiis cymbeeformibus bi-guadrinucleatis. 
Has. On dead bark, Archer. 
Scattered on a subhemispherical pale stroma, blood-red, but not bright. Perithecia rather large, ovate, either 
ending gradually in a papilleeform orifice, or slightly truncate, with a central ostiolum. 4sei linear. Sporidia uni- 
seriate, subeymbiform, with from two to four nuclei or endochromes, des inch long.—In external appearance 
resembling Montagne's N. discophora, but with very different sporidia.
