The species was originally reported on fallen needles of Pinus resinosa and P. strobus in Ontario, Canada. Our systematic work on coelomycetes in Pinus spp. was carried out on 29 different pine hosts (species, varieties, forms or cultivars) at the arboretum of the Montreal Botanical Garden. Choanatiara lunata was isolated (on PDA, MA, CMA) from 9 (31%) of the pine hosts investigated. From those, four hosts are species indigenous to North America: P. albicaulis (subgenus Haploxylon), P. resinosa, P. ponderosa, and P. jeffreyi (subgenus Diploxylon). The other five hosts are pines exotic to North America. Three are indigenous to Europe: P. nigra ‘Laricio’, P. nigra ‘Nigra’, and P. nigra ‘Pallasiana’ (subgenus Diploxylon), and two are indigenous to East Asia: P. densiflora and P. tabulaeformis (subgenus Diploxylon). Except for P. resinosa, these are all new hosts for this fungus.

When shoots were challenge-inoculated after 24 h with 104 to 108 conidia of G. roseum mL-1, in all combinations, sporulation of the pathogen was suppressed completely in leaves, and by > 97% in stems when density of the antagonist was 107 conidia mL-1. Sporulation of the pathogen in stamens and pistils was suppressed more effectively when density of the antagonist was proportionately high. G. roseum developed more extensively in leaves and stamens when postinoculation wetness lasted at least 12 to 24 h at 20 to 30°C, and controlled sporulation of B. cinerea more effectively when conditions allowed the antagonist to establish endophytically.

Among the isolates tested, 312 were from diseased potato cultivars, while 14 originated from tomato or hairy nightshade plants with blight symptoms. A composite of RAPD patterns generated by nine primers following PCR amplification was used to identify novel genotypes based on presence of polymorphic bands.
