Recorded from sandy soil around roots of coconut (Cocos nucifera) in Valenca, Bahia, Brazil, in clay soil at Ilheus, Brazil around the roots of guava (Psidium guajava) and pineapple (Ananas comosus), in loamy sand associated with Gladiolus communis and Hamelia patens (syn. Hamelia erecta). and at Itubera, Brazil in clay soil around roots of Piper nigrum, Syzygium aromaticum (syn. Eugenia caryophyllata) and Hevea brasiliensis (Loof and Sharma, 1975).
