This species has been recorded only once, growing on old fruitbodies of Zeus olympius which itself is known from only two stations. It appears to be a parasite of these old fruitbodies, and may be obligately associated with its host.

Known from one station in Greece.

Only known from a single record, apparently parasitic on fruitbodies of Zeus olympius, itself known from only two stations. The single record comes from within a national park. Extent of occurrence: too little information to calculate. Area of occupancy: a notional 4 km squared.

Apparently parasitic on old fruitbodies of the rare fungus Zeus olympius, itself apparently limited to dead and dying branches of Pinus leucodermis in montane Balkan forests..

As with Zeus olympius, forest fires more frequent because of climate change may be the largest threat. Loss of its only known host may also be a danger.

Need to ensure national park managers are aware of this extremely rare species and its extremely rare host.

Ex situ conservation: isolates of the one collection of Nectria Ganymede are maintained in the ATCC and CABI fungal culture collections.
