Apparently not all Panellus stipticus strains have the capacity to glow, even in North America. It’s supposed to be determined by a single (recessive?) gene that is common in North American populations, but absent from European populations. This is one argument against gene flow between populations on differnt continents. Whether this can be extrapolated to all fungi is certainly uncertain.

but only about half of the collections glow.

Both Douglas Smith and I collected it up at Albion this weekend.

Gary Lincoff & I were discussing bioluminescent fungi last week when he was staying here. Apparently the Eastern NA strains of Panellus stipticus glows, but the European strains do not. Here is some pics of glowing Panellus:

Dr. Dennis Desjardin & Dr. Brian Perry are currently collecting in Micronesia (Pohnpei). As of Friday they had collected 138 species from 67 genera. Of these 138 species, seven are bioluminescent!

Good catch…

I meant to say ‘dark gills’, but one could even argue with that so I went with ‘brown gills’. Thx.

Didn’t realize it glowed in the dark. Anyone on the list seen it do so?

Dark spores?

The spores of Panellus stipticus are white…and the mushroom and its mycelium glows in the dark.
