colony morphology after 7 d growth at 20ºC on CA, V8 agar, MEA and PDA (from left to right)
persistent, semi-papillate to papillate, predominantly elongated ovoid sporangia; scale bar = 25µm
Oogonia with wavy walls containing aplerotic oospores with large ooplasts which turn pale brown on maturity. Antheridia were exclusively amphigynous. Many oospores aborted after the formation of walls. scale bar = 25µm
