Última A review of the Ustilago-Sporisorium-Macalpinomyces complex Naturalis McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Vánky, K.; Scharaschkin, T.. The fungal genera Ustilago, Sporisorium and Macalpinomyces represent an unresolved complex. Taxa within the complex often possess characters that occur in more than one genus, creating uncertainty for species placement. Previous studies have indicated that the genera cannot be separated based on morphology alone. Here we chronologically review the history of the Ustilago-Sporisorium-Macalpinomyces complex, argue for its resolution and suggest methods to accomplish a stable taxonomy. A combined molecular and morphological approach is required to identify synapomorphic characters that underpin a new classification. Ustilago, Sporisorium and Macalpinomyces require explicit re-description and new genera, based on monophyletic groups, are needed to accommodate...

Ano: 2012 URL: http://www.repository.naturalis.nl/record/532423 Taxonomic revision of Ustilago, Sporisorium and Macalpinomyces Naturalis McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Vánky, K.; Scharaschkin, T.. Morphological characters within the Ustilago-Sporisorium-Macalpinomyces complex are defined explicitly. The genera Sporisorium and Anthracocystis are emended to reflect morphological synapomorphies. Three new genera, Langdonia, Stollia and Triodiomyces are described based on soral synapomorphies and host classification. The new classification of the Ustilago-Sporisorium-Macalpinomyces complex incorporates 142 new taxonomic combinations.

Ano: 2012 URL: http://www.repository.naturalis.nl/record/532068 Soral synapomorphies are significant for the systematics of the Ustilago-Sporisorium- Macalpinomyces complex (Ustilaginaceae) Naturalis McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Callaghan, B.; Vánky, K.; Scharaschkin, T.. The genera Ustilago, Sporisorium and Macalpinomyces are a polyphyletic complex of plant pathogenic fungi. The four main morphological characters used to define these genera have been considered homoplasious and not useful for resolving the complex. This study re-evaluates character homology and discusses the use of these characters for defining monophyletic groups recovered from a reconstructed phylogeny using four nuclear loci. Generic delimitation of smut fungi based on their hosts is also discussed as a means for identifying genera within this group. Morphological characters and host specificity can be used to circumscribe genera within the Ustilago-Sporisorium-Macalpinomyces complex.
