but peridium and interior don’t. The spores of L carthusianum are slightly elongated, termed fusoid. The peridium is charcoal-black to gray.
In Kalapooyia brunneum (formerly Leucangium brunneum), the peridium is dark brown with black spots, often areolate in maturity, spores rounded ellipsoid; gray spore pockets.
Leucangium carthusianum should have a white exudate on freshly-cut surfaces. K. brunneum has yellowish exudate.
Spores of L.c. are 65-80 × 25-40 microns. Spores of K.b. are 45 × 30 microns. (Source: NATS Field Guide To Selected North American Truffles and Truffle-like Fungi)
