Abstract
Based on parsimony analyses of eight new SSU rDNA sequences and 24 homologous sequences retrieved from the DNA databases, we suggest a possible phylogenetic relationship of Elaphomycetales with Eurotiales and Onygenales. Our three included Elaphomyces sequences strongly cluster together (bootstrap value 100%) within a monophyletic group (100%) of Elaphomycetales, Eurotiales, and Onygenales. Earlier reports that another cleistothecial lineage (Erysiphe) is related to Leotiales, are supported by our discovery that also another cleistothecial species, Amylocarpus encephaloides, shows affinity to Leotiales. Ascosphaeraceae and Eremascaceae are possibly better accommodated in Onygenales. We describe a new DNA extraction method in which sonication is used to disrupt thick-walled spores. It is useful for both fresh and dried fungal material.Keywords
