Paropsonema is an eldonioid known from the Devonian of upstate New York and (if P. mirabile is a species of Paropsonema rather than Discophyllum) the Silurian of southern Australia.

[4] The species Discophyllum mirabile has been thought to be closer to Paropsonema than to the sole previously-described species of Discophyllum, D.

[5] As a result, sources treat it as Paropsonema mirabile.

[6] Regardless, Paropsonema and Discophyllum are grouped together informally as "paropsonemids.
