This fungus is notable for specific structural features that distinguish it from other members of its genus, and for its niche habitat found only in particular regions of Sicily, Italy.

The etymology of the species name echinulatus is inspired by the echinulate (spiny) ornamentation of its spores, which bears resemblance to those of Pronectria echinulata.

The type specimen was found in Sicily, in the Bosco della Ficuzza region near Palermo, growing on the bark of Quercus pubescens hosting the lichen Physconia distorta.

[2] The fungus possesses perithecia that are black, globular structures growing superficially on its host, measuring between 100 and 250 μm in diameter.

The fungus has been recorded in a few locations within Sicily, specifically in the Bosco della Ficuzza near Corleone and between Mistretta and Nicosia in the Monti Nebrodi.
