This study evaluated the environmental factors that contributed production of sporophore inTyphula phacorrhiza in comparison to data collected on the growth of. ishikariensis and T. incarnata. One experiment was conducted in the lab as well as two experiments conducted in the field. The in-lab trials controlled the soil moisture, soil makeup and light exposure. In the fall 100 sclerotia of six isolates were planted in pots that were filled with a soil and sand mix. Data was taken from the pots weekly, with the maximum sporophore production occurring 11 weeks into the trial. The second field test consisted of five isolates and similar procedures to the first in field tests were followed. In the second trial peak, sporophore production could be seen after 6 weeks.
