REPRESENTATIVE CULTURES: PDDCC 6616, 6798, 6799, 6885.

Colonies on oatmeal agar and malt extract agar in 7 days, 20°c, 50-70 mm diam.; aerial mycelium powdery, composed of greyish to brownish, erect, short hyphae; surface of agar dark grey. Pycnidia light to dark brown, immersed to superficial, solitary, 1-ostiolate, globose, 104-250 µm diam. Conidia hyaline, unicellular, cylindrical, eguttulate, 4-9 x 1.5-2.5 µm. COLONY MORPHOLOGY OA: Colonies 50-70 mm diam. after 7 days. Mycelium; cottony, finely tufted, white, through which the grey agar surface is visible. Reverse; grey. ME: Colonies 60-70 mm. Mycelium of short hyphae, even in height, with a powdery appearance, honey or grey at centre, white at edge. Reverse; brown or olivaceous. CHLAMYDOSPORES: None. CONIDIA: Narrow, cylindrical in shape, often with blunt ends. (4-)6-9(-11) x (1.5-)2-2.5 µm. PYCNIDIA: Solitary, scattered.

OCCURRENCE: Only on Lotus spp., causing stem and leaf spotting. Has been isolated from L. pedunculatus and L. tenuis Waldst. et Kit. ex. Willd.

Coloniae in agaro farinae atque in agaro maltoso per 7 dies, 20°c, 50-70 mm diam; mycelium aerium farinarium; hyphae breves, erectae, griseae vel suffusiae; humila fibrae composita; superficie agari obscure-grisea. Pycnidia dilute vel obscure brunnea, submersa vel superficialia, solitaria, uniostiolata, globosa, 100-250 µm diam. Conidia hyalina, simplicia, cylindrica, eguttulata, 4-9 x 1.5-2.5 µm.

NOTE: P. lotivora has been compared with the European Lotus pathogen, Phoma loticola Died., by Dr G. H. Boerema (pers. comm.). The two species are distinct in both cultural appearance and conidial dimensions. The New Zealand species has cylindrical Conidia whereas those of the P. loticola isotype, preserved in the Swedish Museum of Natural History, are irregular-elliptical with dimensions of 5-7(-12) x 2-2.5(-3.5) µm.

Holotypus: PDD 40427 (PDDCC 6884) ex Lotus pedunculatus Cav.
