L. Opperman et Fc. Wehner, SURVEY OF FUNGI ASSOCIATED WITH GRASS-ROOTS IN VIRGIN SOILS ON THE SPRINGBOK FLATS, South African journal of botany, 60(1), 1994, pp. 67-72
Root- and soil-inhabiting fungi were isolated from various grass speci
es in virgin soil at nine localities on the Springbok Flats with the i
nitial purpose of detecting natural hosts of the crater disease pathog
en of wheat, viz. Rhizoctonia solani Kuhn. Although Rhizoctonia spp. w
ere found at four localities, all isolates were binucleate, and theref
ore not R. solani. Nevertheless, the survey provided qualitative and q
uantitative information on the indigenous soilborne mycoflora of the r
egion. Periconia macrospinosa Levebvre & A.G. Johnson and Fusarium nyg
amai Burgess & Trimboli were the dominant colonizers of grass roots. O
ther fungi which occurred relatively commonly in roots included Fusari
um oxysporum Schlecht. emend. Snyd. & Hans., F. solani (Mart.) Appel &
Wollenw. emend. Snyd & Hans., F. equiseti (Corda) Sacc., F. monilifor
me Sheldon, Phialophora spp., Stachybotrys elegans (Pidopl.) W. Gams,
Gliocladium catenulatum Gilm. & Abbott, Acremonium strictum W. Gams, a
nd Phoma sorghina (Sacc.) Boerema, Dorenbosch & van Kesteren.
