Species Information
Summary: Features include a minute (less than 0.1cm) yellowish fruiting body that is obconic to cup-shaped, with stiff setae arising from the lower and median parts of receptacle, growth on dung, and microscopic characters.
Lasiobolus cuniculi was found in ID and OR (atypical specimens in each case), and also ON, CA, CO, CT, FL, NY, WY, Bermuda, Mexico, Czechoslovakia, France, Germany, Switzerland, and the Ukraine (Bezerra). There are collections by O. Ceska from BC at the University of British Columbia.
