| Abstract/Contents: | "Hymenomycete genera include the anamorphs Rhizoctonia and Chrysorhiza. Species of fungi in these genera have similar anamorphic characteristics, and their respective teleomorphic structures rarely are observed in nature. Comparison of conserved DNA sequences such as rDNA that includes internal transcribed spacer (ITS) 1, the 5.8S ribosomal subunit, and ITS2 can help identify some of these fungi to species. 74 isolates within this class of fungi were recovered from turf tissue samples taken from eight different Florida golf courses. Soil and canopy temperatures, soil electrical conductivity (EC) as a measurement of total soluble salts and soil pH data were taken at each sample date and each location. The species, variety and/or anastomosis group (AG) of the hymenomycete isolates were identified. Soil temperature had a significant effect on isolation of R. solani AG 2-2LP (P < 0.0001) and was negatively correlated (Pearson correlation coefficient, r = -0.61). Soil temperature did not significantly affect isolation frequency of any Chrysorhiza sp. Soluble salt concentration was positively correlated (r = 0.33) with isolation frequency of all hymenomycetes (P = 0.009). Rhizoctonia solani AG 2-2LP recovery was more likely to occur during periods of lower soil temperatures. Chrysorhiza spp. were isolated over a wider range of temperatures. Increasing levels of soil salinity were observed to correlate to higher frequencies of isolation of Rhizoctonia and Chrysorhiza fungi." |
