Handkea is mycorrhizal.

Western Red cedar (Thuja plicata) doesn’t form mycorrhizae, so we can eliminate that from the mix.

However, this fungus can be mycorrhizal with seedling trees as well. So a seedling Mountain hemlock 8 inches tall could be the host for it. Pacific silver fir is possible. Douglas-fir definately possible.

Host could be considerable distance away, or immediatly nearby. A 100-foot-tall tree could be host of a mycorrhizal fungi fruiting 100-200 feet away from the trunk. A 300-foot tree could be the host to mycorrhizal fungi 300-600 feet away from the trunk. So host trees can be much further away than many believe. While many mycorrhizal fungi fruit within the zone extending from the tips of the lowest branches to the trunk, some mycorrhizal fungi fruit much further away.

We were paying attention to the forest; this observation was definitely below the mountain hemlocks. The three species listed above were dominant, with a few Alaska yellow-cedar and western red-cedar as well. I don’t know which species were proximal to these particular fungi.

So are you saying this is a mycorrhizal species? I assumed it was saprotrophic like other puffballs (Lycoperdon, Clavatia, etc).

Host?

Did you happen to notice the host? I most often find H. fumosa with Mountain hemlock above 2,000 feet elevation. But true fir and Douglas-fir are almost always present in the same areas, too.
