Although the form distributed grew in a spring Instead of in rivulets in
peaty regions, yet it seems to agree so well with the descriptions that it is
distributed under this name. The species is distinguished from others of the
moniliforme section by its discoid verticils, its very small cystocarps, by the
very long and abundant hairs, and by its being very gelatinous.
