Trouble with a white crust

Post by Leif » Wed Oct 26, 2016 9:34 am

I collected a rather nice white crust with yellow tinges and a strong chemical smell, growing on beech wood. It formed an extensive patch roughly 50cm across. It looks rather like this:

(I have no evidence to support any ID as yet.) I have tried several times to get a spore print without success, and microscopy of the context is not going so well. Does anyone have tips for this one? I'm assuming it is sporulating, given the season. I will post a photo when I get home, but I suspect a photo is next to useless without microscopy.

Spores are hyaline, allantoid, roughly (3-4) by 1 um2. I finally got a spore print, after collecting a football pitch sized piece of the fungus, and then once I found a piece that would give a print (most bits wouldn't), the damned thing caught a blue mould. :roll:

Sadly I cannot help but this publication may aid with macroscopic identification: http://www.treecouncil.org.uk/Shop-Dona ... 36/CatID/2

There is a companion guide for looking at them under a microscope, too: http://www.treecouncil.org.uk/Shop-Dona ... 37/CatID/2

I showed a dried lump to Alan Lucas and he knew straight away, Ceriporiopsis pannocincta, and I found it within walking distance of the site of the first known British collection! It has less than 200 UK records, so not that rare.

Hah! I guess if someone will know it'll be him.

Hopefully doing a trip round the New Forest with him and a few others in January. Will take a notebook. :lol:
