The fungus is characterised by dark, spherical fruiting bodies producing colourless, round spores, and is found growing on the lichen Normandina pulchella.

The species epithet jamesii honours Peter Wilfred James, recognising his contributions to lichenology, including that of Tasmania, and in whose company the material was discovered.

[2][3] Globosphaeria jamesii produces small, dark brown to black, nearly spherical fruiting bodies (perithecia) that grow on the surface of its host lichen.

[1] Globosphaeria jamesii was first collected in Waratah, Tasmania, in February 1907, where it was found growing on the squamules (scale-like structures) of the lichen Normandina pulchella.

This new specimen, which contained multiple fruiting bodies, was found near Sappho, Washington, USA, at an elevation of 180 m (590 ft) in an area northeast of Beaver Lake.
