No specimen available

This observation is a continuation of my observation 286327 (originally posted as Polyporales sensu lato). I continued to watch the development of these specimens over a two-week period to see if I could eventually recognize a species, or at least a genus. The development was amazingly rapid … from an almost unrecognizable “blob” with a few pores visible to overlapping, clearly defined conks which had even begun to disperse their pores. … in just two weeks. Brown spore dust can be seen in image #0290. See photo captions for time lapse.

38 days since original observation (#286327). These two observations show development of G. sessile from an unrecognizable (to me) “blob” into an easily recognizable, spore producing G. sessile.

Thanks for the ID, Herbert.

That would have been my third choice:):) I thought the rims were too thick for G. sessile, but as I look more carefully at some of the images now I can see some thinner rims developing. I’ll continue to keep an eye on these.

Alternately, this could be Ganoderma
