Facultative Saprophyte – A
fungus or other organism that
ordinarily lives on dead
organic material but has the
ability to exist also as a
parasite on living plants.e.g Beauveria bassiana
A facultative parasite is an organism that
may resort to parasitic activity, but does
not absolutely rely on any host for
completion of its life cycle .
Examples of facultative parasitism occur
among many species of fungi, such as
members of the genus Armillaria .
Armillaria species do parasitise living
trees, but if the tree dies, whether as a
consequence of the fungal infection or not,
the fungus continues to digest the wood
without further need for parasitic activity;
some species even can infest dead wood
without any parasitic activity at all. Thanks for your views
