Remarks (internal):R. butomi, R. saprophytica, R. petrakiana and R. epistroma are morphologically hardly separable. R. butomi emend. is considered a hyperparasitic hyphomycete. The colonies are confined to immature fructifications of ascomycetes. The Australian R. dichosciadii Petr. is very closely allied, but can be distinguished by longer conidia.
