Cannot determine alveolatus from photos provided. Spores of C. alveolatus and C. magnusii should be pitted; spores of C. venosus and C. cookei have sinous rods.

Infrequently collected species. C. alveolatus has been found in Oregon in November.

Odor said to be “Garlicy, pungent, or nauseous.” in Key to Spores of the Genera of Hypogeous Fungi of North Temperate Forests. I have not had the pleasure of smelling it.
