Observation 9619: Tuber lyoni
When: 2001-09-25
No herbarium specimen

Notes: Tim Brennaman sent me samples of these Tuber lyoni from a pecan plantation in Georgia. (See http://interests.caes.uga.edu/...). Tuber lyoni is the newest name for T. texense and Terfezia lyoni, named originally for Lyons, France. This is the first truffle reported in the United States, found on a Mississippi River levee in the 1860’s. The name has since been revised to Tuber lyoni. This is perhaps the most dispersed truffle in North and Central America. It has been reported from just north of Mexico City, Mexico in May under oak trees to Quebec, Canada under pecan trees in November/December. It is additionally reported from Georgia under pecan trees, where apparently reaches its largest size; and from American Basswood in Minnesota, where it is small but very abundant. Under the name Tuber rufum var. nitidum, it has been found under Douglas fir in Oregon. It is edible and quite good, having elements of old milk and fresh cornmeal. It combines these elements admirably when added to a corn chowder.

Recognized by sight: Tuber lyoni always has one or more apical pore leading into the gleba from the peridium. It starts out hollow with a pure white interior, and gradually matures to a complex veination of rich brown spore-bearing material and white sterile veins. The peridium has exceptionally wide venae externae or external veins to 3/4 inch wide. These expand as the truffle matures, giving the sporocarp a spread appearance, often with deep cracks/lobes. I have seen specimens up to 3.5 inches wide. Mr. Brennaman said he was able to gather, with 2 other people, some 25 pounds of fresh material the first time he looked for the fungus!
