I don’t believe this can possibly be Alpova trappei.

Key identification feature in NATS Field Guide To Swelected North American truffles and trufle-like Fungi, by Matt Trappe, Frank Evans and James Trappe, c. 2005, p. 10 is: “Gleba solid, gelatinous, dull yellow in youth becoming dark brown in age, with white to yellow marbling.” This collection has latex (not found in Alpova) and is loculate (chambered), while Alpova should be a mass of gelatinous-filled chambers separated by white to yellow marbling. Also, the odor of A. trappei is desribed as “mildly garlicky to fruity with age”. This collection does not seem to me to be in extreme maturity.

I initially thought the exudate was from a gelatinous context of the gleba. I thought I detected a slightly fruity odor but sometimes suggestion can play tricks with one’s senses. I will attempt to photograph the spores which should be amyloid and with ridges.

Spores are very different

No help from Gilkey, she does not mention an odor. Someone needs to look at the spores. Alpova spores are like Suillus spores and Zelleromyces are like Lactarius.

If this is Zelleromyces gardneri, important to have a voucher collection from it sent to Matt Trappe c/o Oregon State University. This species has not been collected, but what I can find, for quite some time. Also important to have written description of the site where collection was made. Hope you can find more of it.

Zelleromyces possible.

Have not read of it having a fruity aroma, but very little has been written about it. I have a copy of Gilkey’s original Master’s thesis which mentions it. I will look it up and repost here.

I did not realize a latex was present. That by itself mostly negates Rhizopogon, so I will destroy that part of my comments now.

Presence of a latex when slicing a specimen should be included in the original description, Ryane. Keeps us all honest.

may be Zelleromyces instead

When cut in half this mushroom exuded a white latex that is consistent with Zelleromyces. Also it was found in an area that had numerous tanoaks.
