It is the only genus in the family Strangosporaceae, which itself is of uncertain taxonomic placement in the Ascomycota.

[3] The genus was circumscribed in 1860 by German lichenologist Gustav Wilhelm Körber, with Strangospora pinicola assigned as the type species.

[5] Species in the Strangosporaceae are crustose lichens, but sometimes have poorly developed thalli.

The apothecia are biatorine – i.e. more or less lecideine in form, but light in colour and with a soft consistency – and have a poorly developed exciple.

[5] Strangospora species mostly occur in the Northern Hemisphere, and grow on wood, on bark, or over bryophytes.
