Recognized by sight: Cocoon of brownish hair around sporocarp strongly supports Geopora. Lack of Douglas-fir needles points toward a different species of Geopora in my opinion.

Will be taking it to the lab within a few days/weeks. The tree specimens you mailed were Douglas-fir (Pseudotsuga menziesii) and Monterey pine (Pinus radiata). We have only a small 3-acre planting of Monterey pine in Oregon that I know of. It produces quantities of Tuber in September: might want to look in your area for truffles as well!

Could you mail me the dried material?

I could then take it to the Forestry Sciences Lab at Oregon State University and get it identified. The collection would stay at the herbarium there.

Slice the sporocarp in 1/4" slices, and dry. Place inside a waxed paper bag and mail to:

It is likely that Pinus is the host species here. Do you know what species of pine? Could you include that with the collection, as well as your return address? I will attempt to have the people at the Forestry Science Lab send you an identification postcard with the correct identification. Your information becomes an important addition to the range of known Geopora species as well as a reference collection for future researchers.

Oak & pine

habitat but no fir. The second photo shows the specimen as I found it. It was down in a leaf litter hole (like many around the area) that appeared to be made by critters. The collection site is the same as Obs.#64700 3/25/11. I have the specimen refrigerated and can send it to anyone interested.

Geopora cooperi

should be near Pseudotsuga menziesii (Douglas-fir). I see no indication of fir needles in your photos. Could therefore be a different species of Geopora, perhaps one of the lesser collected species.

Looks to have a lot of oak leaves near the collection. Many Geopora species in CA not frequently seen or collected. This could be one of those. Mostly Geopora cooperi does not have (in my experience) an apical pore, which this specimen appears to clearly have. Geopora cooperi typically in my area is hypogeous; this observation appears at least partially epigeous (above ground): another point in favor of a different species of Geopora.

If there was a preserved collection, might be able to come to a better definition of the species. But I have to vote against Geopora cooperi at this time. I do believe this is Geopora in all respects, just not G. cooperi.
