Notes: I collected this fungus December 1992, early summer for us in the South Pacific. I was working for a research organisation and one project was the development of a flock of ewes for milking. To induce lactation the lambs were removed from the ewes soon after birth and kept in a covered shed on a deep litter system. The litter was pinus radiata sawdust which was used to absorb the urine from the lambs. This bright yellow bolete grew in the litter and completely confused me as I only new boletes to be mycorrhizal and not saprobic on wood. I could do nothing with it at the time and filed it away. That is until last week when I saw the picture of Buchwaldoboletus sphaerocephalus in the latest Field Mycologist (Weightman, 2009, particularly p. 118). I believe this to be B. sphaerocephalus but at this stage have not been able to locate a good description, of both macro and micro-characteristics, to confirm it.
I also managed to isolate it into culture and it has survived. It is slow growing and only forms a small mycelium and stains the media dark brown.

Great drawing and image of the culture, I use your field guide quite often and really enjoy Don Horne’s photography.
I look forward to seeing more of your finds!
these curious and compelling saprobic boletes seem to be popping up all over these days…does anyone know their country of origin? what would be the most likely of the four species of Buchwaldoboletus to find its way to NZ?
