| Soil fungi, 70 in number and belonging to 25 different species, were identified. After being obtained by 10-3 dilutions from soil of an experimental plot on the Medway farm, from experimental plots at Ancaster, and from various fields in Middlesex County (on all of which soils potatoes were grown), the fungi were cultured on mold agar and sub-cultured from time to time. Purified cultures were made especially for the purpose of identification. Morphological characteristics were observed on these purified cultures while young, and cultural characteristics were observed on cultures at various ages.; The fungi identified were Aspergillus foetidus, Aspergillus fumigatus, Basidiobolus ranarum, Blakeslea trispora, Botrytis cinerea, Cephalosporium acremonium, Fusarium oxysporum, Fusarium poae, Mucor circinelloides, Mucor corticolus, Mucor racemosus, Pachybasium hamatum, Penicillium chrysogenum, Penicillium duclauxi, Penicillium frequentans, Penicillium herquei, Penicillium janthinellum, Penicillium oxalicum, Penicillium terrestre, Rhizopus arrhizus, Rhizopus nigricans, Spicaria simplicissima, Trichothecium sp., Verticillium cellulosae, and Verticillium terrestre . |
