Ascocarps of an operculate discomycete were produced in soils of a red pine pot culture inoculated with E-strain chlamydospores extracted from soils of a Douglas-fir nursery in Oregon. A new taxon, Tricharina mikolae, is proposed in honor of Dr. Peitsa Mikola. Monoand polyspore isolates show different growth characters and sizes of chlamydospores on both MMN and PDA plates. They form typical ectendomycorrhizae with red pine in flask cultures. Polyspore isolates produce ascocarps in the mycorrhizal synthesis cultures identical to those found initially in soil, whereas monospore isolates do not. This indicates that the fungus is heterothallic. The relationship between E-strain fungi and Complexipes moniliformis is also discussed.
