Periconia ? with white smooth conidia

Conidiophore wiry, 25-35um wide, smooth, dark gun-grey (a bit translucent), evenly septate (cells rectangular, sbout 120 um long) bearing at the top a cluster of white conidia (c. 100) which when in contact with water they eject and spread out. There seem to be no elaborate (if any) branching at the head. I have seen a few conidiophores which where simple branched, (just 1 or 2 branches from the main). Spores oval, smooth (in my opinion) readily staining in cotton blue except a rather thick wall.

Re : Periconia ? with white smooth conidia
What genera are closely related to Periconia please? It seems Periconia have dark conidia that are visibly verrucose (echinose).
