Unknown Fungus


I had name these "Angel Wings" from the 1st foto, but then I see there actually is a fungus with that name. I think these look MUCH more like angel wings but. . . . . I assume these brilliant white fungi start out as spikes but then grow out into flatter fruiting bodies as they grow. The larger of these were probably 4-6 cm tall. I am guessing it could be an anamorph of Xylocoremium flebilliforme, but that is strictly a guess based on the pictures in the guide in the second reference on the right. It is almost certainly a Xylocoremium. I would be very happy if someone could confirm or reject Xylocoremium flebilliforme.


These were found on a downed tree trunk that was 3 meters long and 20-25 cm in diameter on the bank of the Makuma River (650 masl) and above the normal flood line. This section of the Makuma River is in the Amazon rainforest of SE Ecuador.


I saw the white trunk from afar and was amazed to find it nearly covered with this fungus. It reminded me of a heavy frost in NW Iowa. This has to be the most amazing fungus I have seen!

This is most unusual. I found this image this morning, but it gives no details other than it's on the Galapagos Islands - I'll keep looking. Oh, and I can see why Xylocoremium flebilliforme would be of interest. The images in the second reference link look promising.

I haven't seen anything exactly like this one. Xylaria is possible, but I haven't found one that matches yet.
