The protoplasts were filamentous, irregular, oval or amoeboid. Their ultrastructure differed from that of walled cells of the fungus: protoplasts had smaller mitochondria and more stacked, rough endoplasmic reticulum, their plasma membrane had a thin, fibrous coat on the exoplasmic surface, and they lacked the electron-dense bodies present in walled cells. Invaginations of the protoplast plasma membrane suggest that the protoplasts feed by pinocytosis., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-127-2-417
