Chlorochytrium rubrum (Schröter) Freeman
In some water and marsh plants, also in mosses and algae (like the common Enteromorpha) endophytic, intracellular groups of algae are sometimes found. The cause small green warts; if this must be interpreted as parasitism or galling is not evident. The causer mentioned by Buhr and Roskam, viz. Chlorochytrium rubrum, occurring in Lythrum portula and Mentha aquatica currently is
considered unrecognisable at a specific level. Also in Persicaria lapathifolia a comparable organism would occur.
