Observation 9843: Geopora cooperi Harkn.

This is the first hypogeous fungi I cultivated at Paul Bishop’s Tree Farm, beginning in 1985. I first attended a NATS forage there, and found the one truffle species I could then identify on sight: Geopora cooperi. Fuzzy peridium composed of loose felt-like hairs, with an equallly loose gleba that looks like someone tinted a loose head of lettuce, then cut it open. In other words, gleba complexly inrolled. Usually multiple gaps in the peridium leading into the gleba, as shown in these photos. Found the original collection at the NATS forage in December, 1985. Inoculated with half of the sporocarp, sent the remaining portion to NATS for identification and voucher collection. Created twig barrier around the inoculation site to keep potential animals out of site. At a subsequent forage in May, 1986 I stepped on the twigs obliterating the barrier and my only landmark to finding the site again! (OOPS!) So, with nothing to lose, I dug underneath to see if anything was actually forming. To my surprise, I found another Geopora cooperi directly beneath the twig teepee wall! Innoculation does work! In subsequent forages at Paul Bishop’s (he’s had over 40 forages there for mushrooms and truffles) Geopora cooperi has been found a total of 4 times, that I am aware of. The first collection was mine, in December, 1985. The second collection was also mine, in May of 1986. This led to a subsequent multiple innoculation attempts of many hypogeous and epigeous mycorrhizal fungi which at that time had never been grown, including Cantharellus formosus, Tuber gibbosum, T. oregonense, Hymenogaster parksii, Melanogaster natsii, M. tuberiformis, Barssia oregonensis and others.
