Cellophane film overlying agar media enabled dark fruiting in two fungi (Phoma sp. andAscochyta pisi Lib.), fruiting in light on Czapek’s agar in two other fungi [Phoma sorghina (Sacc).] Boeremaet al andLeptosphaerulina crassiasca (Sechet) (Jackson and Bell)] and increased fruiting in all the four fungi. The fungal hyphae branched more profusely on cellophane. The role of cellophane in the induction of fruiting in these fungi is discussed.
