Flood eredi, phis minusve palulo-ramosi, seplati, basi scepe implexi.
deddua, dream apices ramulorum aggregata.
Filaments erect, with more or less spreading branches, jointed, often interwoven
at the base. Sporidia deciduous, collected around the summits
of the branches.

Tufts at first distinct, a line high, at length becoming confluent, and covering
(as L in k correctly observes) the fungus with a white down. Filaments
very much branched, the ramuli acute, alternate. Sporidia large,
oval, very numerous, and collected in a crowded manner about the extremities
of the branches.
In the Mycologia Eiiropsea of the celebrated P e r s o o n , we
find several genera which had been established by the German
botanists, reduced to B o try tis; as Cladobotryum and^ Vir-
g a r ia of N e e s , Stachylidium of L in k , and Vzrticillium
of N e e s . I t is probable he is correct, except in Stachylidium
and Cladobotryum,, which may he good genera. V irg a ria was
considered by L in k as a division of B o try tis, only distinguishable
by the mode of branching. Verticillium passes at once
into B o try tis through B . allochroa. Cladobotryum is dubious,
and very peculiar in its cylindrical sporidia. I would
not, therefore, hastily contradict so acute a botanist as N e e s
