“…Though uncommon, studies showing non- Rhizoctonia -like fungi forming OM have increased since the early 2000s [ 20 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Those genera include strong pathogen [ 6 , 30 , 33 , 38 ], saprobes [ 39 , 40 ], ectomycorrhizal fungi [ 41 , 42 ], and ascomycetous fungi [ 20 , 43 ]. Another unique orchid trait is mycoheterotrophy, which involves the utilization of OM symbiosis to obtain carbon, but does not reciprocally provide the fungi any nutrients [ 42 , 44 ].…”
