Abstract
From the necrotic stem of aquaculture Dracaena for living room decoration, we observed conidia on acervuli with occasional setae and perithecia in vivo. Morphological characters were; acervuli, dark brown and 300- 500 mm in diameter; conidia, hyaline, aseptate, cylindrical to slightly ellipsoid with rounded apex and narrow truncate base on phialidic conidiophores, 12.5-17.5 mm; setae, variable in length 1-4 septate, slightly swollen at the base and tapered to the apex, 200 mm; appressoria, dark brown ovate to obovate irregular 5-12.5 mm, perithecia on decayed stem, globose, dark brown and black 85-300 mm; asci 8 spored, clavate to cylindrical; 50-62.5 × 8-10 mm; ascospores, oval to fusiform, sometimes slightly curved, aseptate, hyaline. Above characteristics were also confirmed in vitro. Colletotrichum state of this fungus was also compared with C. lindemuthianum and C. musae in terms of morphology of conidia and setae and growth on PDA etc. This fungus was identified as Glomerella cingulata(Stonem.) Spaulding & Schrenk(Colletotrichum gloeosporioides(Penz.) Sacc.).
Key Words: Dracaena sanderiana, Glomerella cingulata, necrotic stem of aquaculture Dracaena
