This study indicated that Ceratorhiza
cerealis was isolated from Goodyera procera. The
teleomorph state of this fungus, Ceratobasidium
cerealis is a cosmopolitan, saprotrophic, plant
parasitic and orchid endomycorrhizal species.
Burpee (1980) reported that Rhizoctonia cerealis
caused chlorosis and blight of turfgrasses.
However, this fungus was also used to germinate
orchid seeds. Weber and Webster (2001) reported
thatRhizoctonia cerealis causing sharp eyespot on
the stem base of cereals and grasses. This fungus
was tested to stimulate the germination of
Dactylorhiza maculata ssp. ericetorum seeds in
vitro. The result showed that the orchid seeds
could germinate within 30 days and the protocorm
developed a green shoot tip after expose to daylight
within 90 days after sowing. Smreciu and Currah
(1989) reported that Ceratobasidium cerealis,
teleomorphic state of Ceratorhiza cerealis
stimulated germination of eleven orchid species in
Canada.
