Mollisia sp. cf. ventosa
I found this fungus on a piece of moist bark on a fallen branch at Decoy Heath reserve.
When I saw it I knew two thing, that it was new to the official list of species and that is was probably in one of the genera most difficult to identify to species. I also new that I was unlikely to get specialist help.
After must searching, but no microscopic examination, I found that is most resembled Mollisia ventosa. There may be a difference in the shapes of the edges of the fruiting bodies.
However, that, according to my comprehensive book, was found on barkless dead oak. I have seen images, supposedly of this species, on bark.
I cannot identify the bark of fallen branches but I saw no oak trees. I include a photo of the bark, a piece about 60mm x 30mm.
This was the only sample I took home. After I had my meal, I was about to photograph it. when I found that, still in the closed, airtight plastic box, the fungi had shrunk and were scarcely visible on the bark. Clearly, they needed very moist conditions so I added some water and closed the lid.
When they had expanded, I took a series of photos with the widest FOV, where I show 3 fruiting bodies, 7mm wide.
One of the higher magnification images has been cropped.
