116 REVISION OF THE Хоктн AMERICAN HYDNACEAE 
cm. long, 1-1.5 cm. thick, and fertile secondary branches 0.5—1.5 
cm. long, 2-5 mm. thick, often appearing as mere protuberances 
on the primary branches; substance fleshy, brittle to somewha 
tough; teeth slender, terete, pendent chiefly from the secondary 
branches forming terminal drooping clusters, occasionally fascicu- 
late on the primary branches, 3-10 mm. long ; spores globose or 
. subovoid, white, uniguttulate, 5.5—7 и wide; taste mild but some- 
what сила able.

Specimens of this species are often referred to М. caput-ursi, 
which the plants greatly resemble. But in the latter species the 
ultimate branches spring from a massive tubercle, while in Æ. cor- 
alloides the whole plant is branched as in 27. laciniatum. From 
the latter species Æ coralloides is distinguished by its larger spores 
and its relatively coarser branching, and especially іп possessing 
two orders of branches, the primary without teeth except as borne 
in fascicles, generally on slight protuberances as if abortive branches, 
and the secondary, short usually straight branches bearing straight 
pendent teeth clustered chiefly toward the ends. The last feature 
frequently gives to the plant an appearance much like И. caput- 
ursi and doubtless has led to confusing the two species. The 
teeth are usually longer than in Æ. /aciniatum, but this feature, as 
in all the species of this genus, is too variable to be of special value 
in specific diagnoses. 
That the plants here described as Æ. coralloides Scop. are true 
* These figures are given for М. cafut-ursi, but in that species the branches are 
short and spring from a central tubercle, giving a more massive effect. In other respects 
the two species are very similar. Тһе figure in the second edition is much superior to 
that in the first. 
+ The plates are marked ИМ. caput- Medusae, but that species is not branched.
