Genus Teratomyces Thaxt.

MB#5374

Proceedings of the American Academy of Arts and Sciences 28: 182 ( Thaxter 1893). –

Type species: T. mirificus

Brief description

Monoecious. Receptacle multicelled, symmetric, with cell II subdivided by horizontal septa into cells IIa, IIb, and a distal cell III which divides repeatedly by oblique septa forming a secondary receptacle bearing numerous appendages and one to a few perithecia. Antheridia seriated and intercalated with lateral efferent necks, or free, flask-shaped and terminal on the appendages. Acute sterile branchlets present.

Remarks

The genus consists of ten species, of which four in Europe, two in Denmark. The most recently described species is T. cylindrocarpus ( Rossi & Bernardi 2018) . With the same thallial structure as Symplectromyces , it can be distinguished from it by the pointed branchlets and antheridia present on the appendages.
