Cn all sorts of decaying substances. Common.
[United States.]
One of the commonest of Fungi, and very variable. Numerous species
have been characterized, but it is questionable whether many of them should
not be united under this, which scarcely claims a place as a distinct species,
since Tulasne has indicated its affinity with Sphceria herharum, of which he
regards it as a conidiophoms condition, as well as Macrosporium sarcinula.
