On Potato Sucrose Agar (PSA). Colonies. After 4 days growth ranges from 5.15-5.85 cm diam. with a mean ñ SD = 5.52 ñ 0.21; aerial mycelium hairy to felt and powdery with the formation of microconidia; aerial mycelium white to brownish red, white with pastel red or white to reddish brown; pigmentation dark red or brown red pigmentation. On Potato Dextrose Agar (PDA). After 10 days growth ranges from 7.15-8.65 cm length with a mean ñ SD = 7.96 ñ 0.47; aerial mycelium for some isolates white to reddish brown, and for others white to grayish rose; all isolates producing reddish pigmentation; mycelium very infrequently forming "chlamydospores" (not a reliable taxonomic character) in clumps or chains in older cultures. Teleomorph. Not known. Anamorph. Sporodochia sometimes formed. Conidia. Of two types; macroconidia slender, rather short, and falcate to almost lunate, 20-40 × 3-4.5 μm, 3- to 5-septate, but mainly 3-septate; apical cell curved and tapering and basal cell with well-developed foot; microconidia abundant, globose or napiform, sometimes with a distinct papilla, 7-12 × 7-10 μm, usually aseptate but occasionally 1-septate, produced in grape-like clusters on globose to doliiform "monophialides". Notes. This species grows on Glycerol Nitrate Agar (G25N) producing pale yellow, pale orange aerial mycelium and orange, orange-red pigmentation; growth on Czapek-Dox Iprodione Dichloran Agar (CZID) results in reddish white aerial mycelium and brownish red pigmentation; growth on mannitol medium results in grayish, brownish yellow pigmentation. The fungus produces urease, peroxidase and phosphatase enzymes, but does not produce acid on creatine-sucrose agar.

Gibberella tricincta is a fungal plant pathogen. Gibberella tricincta produces the antifungal alkaloid Fungerin.
