see my comments under the first Gautieria I commented on.

it appears that your Gautieria specimens are all different.

nice work.


Presence of fungal mat

would also be beneficial. M.J. Trappe has documented G. monticola with T. mertensiana and Abies procera in Oregon. Fungal mats are dense, felty often tough aggregates of usually single-species mycelium. They hold soils together, and can be hydrophobic, allowing excess water to drain quickly, especially from steep slopes.

Mature Gautieria monticola should have a cinnamon-brown gleba and soon loses peridium in maturity. This might be extremely young G. monticola which has yet to reach maturity and has retained most of its white peridium.

I still have a problem with the locules, but the section shown is close to the peridium, and does not necessarily show much of any columella or pseudocolumella.

Tsuga mertensiana?

The needles nearby appear to be Mountain hemlock. Don’t have an elevation, but that might prove hemlock species. I am unfamiliar with the area.

If mountain hemlock, this could also be a Gautieria. Fungus is loculate, but loculates are not any consistent size and appear more convoluted and with irregular tubes, suggesting a closer relationship to a poroid mushroom than most hypogeous fungi with same-sized locules. Also, the gleba is such a bright color that it might attract birds to predate on it – or on insects predating on the fungus itself, thereby insuring dispersal.

In my area, T. mertensiana not generally found below 4,000 feet elevation. In BC, elevation might easily be closer to 7,000 feet or to tree line.

The one photo of Fevensia I have is not as brilliantly colored, and has nearly uniform locule size, which are not nearly the extensive size of this obs.

In the absence of any other suggestion, I will suggest Gautieria.

three cheers for confusing hypogeous fungi!

Possible Fevensia?

Fevensia aurantiaca said occur in relatively mature forests of Douglas-fir and true fir. Peridium pale orange; locules of gleba spherical yellow, often goblet-shaped. If Fevensia, a great extension of the known fruiting area, currently only known from the Coast Range of Oregon. I’d suggest sending this to Matt Trappe, Johann: it is not something I am familiar with, and probably shouldn’t be making a guess on. It might even be a new species.
