Phialophora clavispora W. Gams, 1976 Rhopalophora (from Greek ῥόπαλον (rhópalon) 'club' and -φόρος (-phóros) 'bearing') is a genus of lichen-like fungus in the family Dactylosporaceae.

[3] Members of Rhopalophora are lignicolous fungi of mycelium made of hyaline or pigmented hyphae that are occasionally monilioid.

Their conidiophores are pale brown in color, unbranched, macronematous (i.e. morphologically different from vegetative hyphae), often reduced to phialides generated directly from undifferentiated hyphae, sometimes with percurrent regeneration.

Phialides are light brown in color, paler towards the tip, integrated, subcylindrical and sometimes with sympodial proliferation, tapering toward the collarette.

The conidia are hyaline, aseptate, clavate, truncate at the base, and arranged in chains or heads.
