Which of the following is a classic example of an endobiotic fungus (a fungus living entirely within the tissues of its host)?
- AAgaricus
- BMorchella
- CSynchytrium
- DPolyporus
Solution & Step-by-step Explanation
Synchytrium endobioticum is a primitive chytrid fungus that lives as an obligate endobiotic pathogen inside host cells. It causes the destructive "black wart" disease in potato tubers. The other choices (Agaricus, Morchella, Polyporus) are free-living macrofungi.
