in that position in some instances, and the same is true of the 
type specimen of Microcera pluriseptata Cke. and Massee, which 
is identical with Microcera coccophila Desm., the conidial stage 
of Sphaerostilbe flammea. This has not yet been observed in 
Sphaerostilbe coccidophthora, but the available collections of the 
latter species are few in number. 
Relying upon Berkeley and Broome’s description and figures, 
von Hohnel has transferred Nectria aurantitcola to Corallomyces 
because it has perithecia on the synnemata. Obviously, in that 
case, Sphaerostilbe flammea must be transferred to Corallomyces, 
and this has been effected by von Hohnel in Herb. Kew, as far 
as regards the type of Nectria laeticolor. On this classification, 
the closely-allied Nectria coccidophthora must be left in Sphaero- 
stilbe. But the production of perithecia on the synnemata is 
exceptional in both Sphaerostilbe aurantiicola and Sphaerostilbe 
flammea, and it does not seem reasonable to separate those two 
generically from Sphaerostilbe coccidophthora on a character 
which is seldom developed. 
The genus Corallomyces was established by Berkeley and 
Curtis in 1853, the type species being Corallomyces elegans, 
described from specimens from Surinam in the Schweinitz 
Herbarium. It was said to have a branched stroma, with 
filiform and palmate branches, and to be a Hypocreaceous 
genus corresponding to Xylaria. Berkeley and Curtis published 
figures of their species (Journ. Acad. Sci. Philadelphia, n.s. II, 
Table XXV, fig. 2), showing short, simple, or slightly branched, 
clavae, in one case flattened at the tip. Another figure, by 
Lindau, was published in Engler-Prantl., Pflanzenfamilien, 
Th. 1, Abt. 1, p. 366; it shows a shrubby growth of suberect, 
much branched stems, arising from the same point. The latter 
figure is said to be original, but there is no indication of the 
origin of the specimen from which it was taken. The type 
specimen of Corallomyces elegans in Herb. Kew, “‘Corallomyces 
elegans B. and C., Sphaeria pseudovillosa Schw., Surinam, Herb. 
Schwein.” is a dense group of old synnemata, arising side by 
side from the substratum; some of these are once branched, 
others simple, and there appear to be a few horizontal rhizo- 
morphs in addition; the perithecia are borne on the old synne- 
mata. There is nothing in the type specimen which would 
support Lindau’s figure. 
Corallomyces is merely a Sphaerostilbe which has produced 
perithecia on the old synnemata. The type species, Covallomyces 
elegans, is Closely allied to Sphaerostilbe repens, a rhizomorphic 
species which may produce perithecia on the rhizomorphs or 
on the old synnemata. It would appear to be the rule rather 
than the exception, that species of Sphaerostilbe may produce
