Acrospermum was first established as a genus by T o d e
in his “ Fungi Mecklenhurgenses selecti,” with the character
“ Fungus simplicissimus, suberectus, apice extus fructificante.”
I t only differs from Sclerotium, according to the correct observation
of F r ie s , in the fructification being confined to the
apex.
In the perfectly recent state in which I examined this plant,
it appeared to me, that the outer substance formed a nearly distinct
covering to the interior mass, which, again, seemed to he
composed of a dense mass of pale filaments, not furnished with
any joints. Some of these filaments it was no difficult matter
to remove from their situation; and then, as most distinctly
seen, I drew the Fig. 6. in the annexed plate. I am sorry,
that, with all my care, I have never been able to find the sporidia,
though, from the combined authority of T o d e and my
friend F r ie s , there can he no doubt of their existence.
