Species Lists


Thanks to everyone for the input. This young fruitbody (P1051140) was growing next to the discussed species (158197) . Could be same species (or not). At the day the picture was taken there was rain in the morning, but the fruitbody was shiny as shown on picture.

I agree with Dave’s points. We don’t often see that large a margin in ganoderma, but we are not in the tropics – and we never see I. with a varnished cap. I stand corrected.

newly emerging fruit bodies of Ganoderma tsugae. Of course it is almost certainly not this species. But the similarities are: thick rounded white margin, emerging shiny/varnished skin on upper surface. G. tsugae often first appears as hemispherical white buttons before the shiny surface develops.

This looks too shiny for I. resinosum. But, if the specimen seen here was wet when photographed, this may have exaggerated the shininess.

Young fruit bodies of I. resinosum are fairly soft/pliable. Young fruit bodies of Ganoderma tend to be only slightly pliable; not quite rigid.

There are other genera of “varnished polypores” other than Ganoderma with tropical distribution. I don’t know if “Ganodermataceae” includes all of these.
