You quote the spores as 7.5 -19.5 but looking at your micrograph they all look to be in the 7.5-9.5 range. Which is right? The colour does tend to vary but your spores do look quite pale for klenii so I think P crystalinus is the most likely. (unless the spores do reach 19.5)
Mal
"Spores 7.5 - 19.5" is a quotation from the key.
The spore sizes I measured: Me: 10.2 x 6.4 µm, N = 10
So I will name this find P. cristallinus!
Thank you very much for your help!
Riet
To be sure ...
This afternoon I will measure the spores ejected to the lid of the plastic box.
To be continued Hans :-) Dank je voor jouw reactie!
The sporangia on the lid showed already two kinds of spores.
So nice (and very educational) to see the difference!
Key:
Spores 7.5-11 x 5-7.5 µm, pale yellow ...................................................P. crystallinus
Spores 10-19.5 x 5.5-9.5 µm, usually deeper yellow/orange....................P. kleinii
It was very hard to find a fruitbody of P. kleinii, but in the end I succeeded :-)
Mooi succes. Groet
Hans
