Unknown Paxillus (Cambridge, UK)
There is a Paxillus that I can't identify that grows every year in my garden. It is very like P. involutus, but is twice the size (8-12" in diameter). It is either mycorrhizal or harmlessly parasitic on birch. Any ideas? Regards, Nick Maclaren. |

A last followup. http://www.bioimages.org.uk/HTML/B147197.HTM Hah! If all of the books have been wrong about the size of P. involutus, as Alick is quoted as saying, then that is the likely species. I shall fiddle with ammonia, and see if I can manage to make my father's field microscope work on the spores, but it was really only the size that made me doubt P. involutus.

It often reaches 6-8 inches, and I wouldn't be surprised to see a 12" diameter specimen, although IMO few are likely to reach that size. Daniel B. Wheeler |

From the reference in Field Mycology, it appears that few books have caught up with even the 6-8". With the correction that up to 10" or so occurs, everything falls into place.
