Coniophora arida

Post by Leif » Sun Dec 04, 2016 12:10 pm

I found this last week on some fallen beech. It's a rather attractive splat and not easy to ID with certainty as C. puteana is very similar. C. arida is separated by having dextrinoid spores. I've attached photomicrographs of spores in KOH and Melzer's, it should be obvious which is which. This is var suffocata as the basal hyphae have crystals. These two species are common, but probably ignored by most of us amateurs.

I once inadvertently cultured C. puteana. Putting folded up cardboard boxes in the cellar of my first little home as I moved in and promptly forgetting about them :roll:. A couple of months later and quite a good growth, extensive mycelium and well-developed hymenium. Panic for a short while as my first thought was "dry rot!!!!" :shock:. The cellar hadn't seemed damp when I'd first checked . . . . . :oops:
