Phoma crystalliniformis (Loer. et al.) Noordel. & Gruyter
Nomenclature:
Phoma andina var. crystalliniformis Loer. et al. (1986) is the basionym. This fungus was considered by Loerakker et al. (1986) to be a distinct species from Phoma andigena (see nomenclature fact sheet) because it is found on tomato in addition to potato, grows more quickly on agar, and forms white crystals precipitating in the medium as long dichotomous branching strands.
Distribution:
This species is found in the Andes of South America (including Colombia) between 1500 and 3700 m.
Nomenclature Report:
