Notes.

Stilbohypoxylon was established by Hennings (1902) to accommodate S. moelleri as the type species. Morphologically, this genus is characterized by black, globose to pulvinate stromata, cylindrical asci with a J +, apical ring; and brown, ellipsoidal ascospores surrounded by a thin mucilaginous sheath and a straight or spiral germ slit. Stilbohypoxylon species have geniculosporium-like asexual morphs ( Hennings 1902; Rogers and Ju 1997; Petrini 2004; Daranagama et al. 2018). Based on morphology and phylogenetic studies by Daranagama et al. (2018) and Wendt et al. (2018), Stilbohypoxylon was accepted in Xylariaceae . Stilbohypoxylon species cluster with Xylaria species in two subclades, providing evidence that this genus is polyphyletic ( Hsieh et al. 2010; Li et al. 2017; Daranagama et al. 2018; Wendt et al. 2018). Hyde et al. (2024) listed 20 species under this genus, while 18 are included in the Index Fungorum (2025).
