Aerial growth of dikaryotic colonies of H4-8 (A) and Δtea1 (B,C,D). Strain Δtea1Δtea1 produced less dense and high aerial hyphae when transferred to light (B) and only forms small clusters of fruiting bodies (C and D). Arrow indicates the transition from dense aerial hyphae production to thinner aerial hyphae production upon light induction.
