Phoma paspali P.R. Johnst. 1981

Collections Examined

REPRESENTATIVE CULTURES: PDDCC 6614, 6615, 6819.

Description

Colonies on oatmeal agar and malt extract agar more than 90 mm diam. in 7 days at 20°c; aerial mycelium cottony, grey; hyphae erect, long, reaching the lid of the petri dish. Pycnidia light to dark brown, immersed to superficial, solitary to gregarious, 120-250 µm diam. Conidia hyaline, unicellular, oblong-elliptic, egguttulate, 6.5-11 x 3-4 µm.

COLONY MORPHOLOGY OA and ME: Colonies 70-90+ mm diam. after 7 days. Mycelium; grey, cottony, with long hyphae reaching the lid of and completely filling the petri dish. Reverse; dark grey or black. CHLAMYDOSPORES: None. CONIDIA: Uniform in shape, oblong with rounded ends. 6.5-9(-11) x 3-4 µm. PYCNIDIA: Solitary, dark walled with a single ostiole.

Habitat

OCCURRENCE: Saprophyte or weak wound parasite. Has been isolated from Lolium perenne, Paspalum dilatatum, Dactylis glomerata L., and soil.

Latin

Coloniae in agaro farinae avenae atque in agaro maltoso per 7 dies, 20°C, magisquam 90 mm diam; mycelium aerium foccosum, hyphae erectae, praelongae, griseae operculum patina petri attmgentes. Pycnidia dilute vel obscure brunnea, submersa vel superficialia, solitaria vel gregaria, 120-250 µm diam. Conidia hyalina, simplicia, oblonga vel ellipsoidea, eguttulata, 6.5-11 x 3-4 µm.

Notes

NOTE: An Ascochyta sp., possibly A. graminea (Sacc.) Sprague et Johnson, is similar to P. paspali in cultural appearance; however, its conidia are always 1-septate and it has a slower growth rate (40-60 mm in 7 days).

Holotypus: PDD 39975 (PDDCC 6614) ex Paspalum dilatatum Polr.
