Ascomata 140–165 μm high, 150–175 μm wide (x̅ = 142.5 × 155.2 μm, n = 10), superficial, solitary or aggregates, scattered, sub globose, ostiolate Peridium brown, single layer, thick minute parenchymatous cells. Asci and ascospores not observed. Asexual morph: Unknown.

Importance and distribution

There are five records of Hyalocrea in Index Fungorum (2022), but three species have been transferred to Paranectriella. Hyalocrea species morphologically show some similarities to the genus Calonectria, Paranectria and Paranectriella (Hyde et al. 2013). Hyalocrea epimyces is known from stroma of Catacauma elmeri (Phyllachoraceae) in Asia (Philippines) and H. jasmini was found on Jasminum dichotomum (Oleaceae) in Africa (Uganda).
