Isozyme analysis of different species of the genus Saccobolus (Ascomycetes, Pezizales)

In this work we accomplished the isozyme analysis of monosporic strains of ten species of the genus Saccobolus, with the aim of establishing: the precise identification of some especies among which, the continuous variation of some characters poses doubts about their delimitation, interspecific rela...

No differences were observed in the state of the characters between the monosporic strains of each geographical isolate. Esterases was the only system in which differences between some geographical isolates were observed within the same species, resulting in a total of 15 band patterns.
