large (20cm diameter) fungus by rowan log pile

[pbrighto]

Currently (Jan/Feb) growing out of or next to the pile of wood from a diseased rowan felled last year -may arise from roots of the same. No colour changes or fluids exuded when a piece broken off - see photo 2. Having been through the Collins photo guide I have not found any plausible matches - so I would be grateful for any clues or ideas.



Thanks, Phil

Hi

What colour are the spores?

Hi Peter

I have not so far succeeded in getting a spore print. The specimen is still in the garden - are there any other features to look for?

Thanks

can you get a shot of the way the gills meet the stem? (insofar as it has one); do they run down it? I'm wondering Pleurotus cornucopiae

That's what I was thinking Chris:

The best thing to do is to remove a cap and make a spore print. P.cornucopiae has very pale lilac spores. P.ostreatus also has lilac spores but the cap is usually a darker colour, and some Plerotus species have white spore. Also as Chris says the gill attachment is also important

It is always best to make a spore print at the first opportunity; it can often make things so much easier. Many books have the toadstool fungi in order of spore colour so you can often eliminate ¾ or more of the species in a book following a simple spore print.

Thanks for the help in getitng me to Pleurotus. The specimen is too far gone now for spores or smell - but here is a detail of the gill attachment to the stipe. Can this resolve between P. ostreatus and P. cornucopiae? Phil

This would suggest P.cornucopiae but cannot be a definitive answer.
