Title: Parasitism and Nutrition of Gonatobotrys Simplex
Abstract: Most of the early studies of fungi parasitic on other fungi have dealt principally with mode of parasitism or host range. Ayers (1933, 1935, 1941) was one of the first investigators to emphasize nutritional and physiological aspects of mycoparasitism. Several investigations have dealt recently with physiology of biotrophic mycoparasites and the influence of environment and nutrition on their parasitic activities. Barnett and Lilly (1958) reported that Calcarisporium parsiticumn Barnett parasitizes species of Physalospora and related fungi by making close contact with the host and absorbing nutrients through small, specialized buffer cells at the point of contact. This fungus was later cultured axenically on media to which extracts of other fungi were added. Berry and Barnett (1957) and Berry (1959) described the parasitism of Piptocephalis virginiana Leadbeater & Mercer, which obtains nutrients from other species of Mucorales by means of haustoria. This mycoparasite, in contrast to C. parasiticurm, has never been grown in the absence of a living host. A short time later, Shigo (1960) showed that Gonatobotryum fuscum Sacc. parasitized species of Ceratocystis and related genera by means of foot-like, absorptive hyphae which made contact and adsorbed nutrients without penetrating the host cells. He also described a condition which
