Resumen:
The genus Coprotus consists of coprophilous fungi in the Pyronemataceae.
44 monosporic strains were morphologically identified as Coprotus lacteus, C. niveus,Coprotus consists of coprophilous fungi in the Pyronemataceae.
44 monosporic strains were morphologically identified as Coprotus lacteus, C. niveus,Coprotus lacteus, C. niveus,
and C. sexdecimsporus. Using random amplified polymorphic DNA (RAPD) to analyse
two C. lacteus, five C. niveus, and two C. sexdecimsporus geographical groups, the
authors obtained diagnostic bands for species recognition, estimated polymorphism
levels within species, analysed inter-species phenetic relationships, and compared the
findings from the RAPD study to those from a previous isozyme study. The phenogram
obtained from Nei´s genetic distances matrix was similar to the one previously obtained
by isozyme markers. Both matrices show strains grouping into three defined clusters,
each representing one of the three species analysed. The difference between the
similarity levels among species and those observed in the isozyme report are compared
and discussed. The results of this study support the use of RAPD markers as a reliable
tool comparable to traditional morphological and isozyme methods.C. sexdecimsporus. Using random amplified polymorphic DNA (RAPD) to analyse
