Thallus e Jilamentis decumhentibus implexis, ramosis, septatis. Spondia solitaria
cequaliter pedicellata.
Thallus composed of decumbent, entangled, branched and jointed filaments.
Sporidia solitary, on pedicels of equal length.

Acremonium fuscum, Schmidt, in Mylcol. Hefte, 1. p. 79- t- i- ^3. Pers.
Mycol. Europ. 1. p. 27.— Grev. FI. Edin. p. 468.
H ab. On dead wood and damp stems of large herbaceous plants when decayed.
Autumn. Near Edinburgh.
Thallus spreading, like a very fine w e b ; of an olivaceous colour. Filaments
remotely branched, much interwoven, jointed, pellucid. Spondia globose,
somewhat opaque, their pedicels arranged alternately.
W ith this, neither of the other two known species is likely
to be confounded; the thallus in both being of a white colour.
A s a genus, Acremonium is well defined; and as a microscopical
object, it is far from being the least interesting of the
Order to which it belongs.
