Notholca acuminata, malleate trophi (3)
 
Notholca acuminata, with the intention not to kill unnessarily a living specimen for trophi maceration a dead specimen was sampled, compressed and macerated with NaOCl. Only after dissolving of the lorica it became apparent that this specimen had been heavily infested by the fungus Zoophagus. The chitinous hyphens of this fungus are resistant against NaOCl and are therefore visible here. (3)
