[2] Stilbum vulgare forms groups of minute, gelatinous, synnema-like basidiocarps (fruit bodies) up to 0.5 mm tall with a distinct stem and inflated, fertile head.

Microscopically, it produces auricularioid (laterally septate) basidia and basidiospores that germinate by budding off yeast cells.

The species has been collected on rotting wood and old agaric fruit bodies and may be a parasite of other fungi.

[4] As well as Stilbum vulgare, he included several other species of similar size, texture, and shape within the genus.

Re-examination of specimens in the twentieth century showed, however, that nearly all these species were anamorphic members of the Ascomycota, many of them subsequently assigned to the genus Stilbella.
