Used references: Field Guide to North American Truffles, p. 36. “Spores 10-16 × 7-9 microns, elongate citriform, longitudinally ridged.” I’ve found this species only once, so hope someone can check my opinion. My collection had a gleba much darker red, and was apparently more mature. The date this collection was found seems quite early to me as well. But it is California and allowances must be made for elevation and latitude.

Any microscopy with this? The cartilaginous columella is certainly present, and the coloration resembles H. occidentale in Field Guide to North American Truffles. It is loculate, though, and the locules look too large for Hysterangium, at least to my eye. Looks to me more like Gautieria, perhaps something similar to G. pterosperma, also found in CA, also with cartilaginous columella, but with larger locules. Many Gautieria have extremely strong odors, a single sporocarp may drive you from your car on a warm day, according to Welles Bushnell.
