Observation 206974: Tuber P. Micheli ex F.H. Wigg.
When: 2015-06-18

Notes: Truffles were found and given to me. Found in residence lawn by Birgitta Hietala when digging around base of spruce (black or Norway; I saw a twig but not the cones) trees. Were hypogeous. Smell very truffly, similar to Romano cheese; taste reported “mild, pleasant, a bit peppery aftertaste.” I did not taste them personally but the smell was fantastic. Size was about that of a pea (pretty small); a larger one that I did not see was reported to be 3-4 X the size of the others. Pretty smooth on the outer surface; lozenge-shaped to almost globose.

The specimens are on their way to U of FL and will be getting sequenced by Roseanne Healy and Matt Smith. I’ll update information as I get it.

T. maculatum possible, but not likely.

T. maculatum is not known to associate with Black or Norway spruce. It has been found often in NA, so that part is possible. It is known from southern Canada coast to coast, and from northern U.S. The most common mycorrhizal associates are Pinus, Abies, Pseudotsuga, Corylus, Quercus, and Salix. If it is associated with Picea, this is a first for this species.

This species was misidentified in New Zealand as T. melanosporum by Ian Hall, then identified as T. maculatum by Trappe. Without spore microscopy, it is difficult to assess the species. It might be T. maculatum as stated, or could well be a species novum previously unknown.

It is a Tuber species. Consider sending it to Dr. Charles LeFebre for identification.

Maybe.

It is listed in Trappe et al.‘s North American Field Guide to Truffles. I hopeful that an expert may want to look at them. I’ve not had any luck trying to contain Jim Trappe. I’m also trying to contact Roseanne Healy.

then what’s this?

It seems overseas mushrooms end up being different species, & sometimes just variations, than what we find here. I’d think this isn’t therefore too likely T. maculatum, unless it came as a transplant of a tree grown over seas.

Dunno. Tuber maculatum is known…

from Europe and southern hemisphere (New Zealand). It is discussed in Trappe et al. Field Guide to Truffles.

Wow, Tubers over there!

I looked it up, but the usual fungal websites don’t seem to list it. What’s up w/that?
