Abstract

CINTO, Isabel E.; DOKMETZIAN, Diana A.  and  RANALLI, María E.. Iodophanus carneus and I. testaceus (Ascomycota-Pezizales): Independent taxonomic identity or synonymy? A study of their morphology and isozymes. Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.3-4, pp.181-187. ISSN 1851-2372.

The aim of this study was to delimit two Iodophanus species: I. carneus and I. testaceus , based on morphological characteristics and electrophoretic patterns of their intracellular isozymes. Twenty monosporic strains were used, including five belonging to I. granulipolaris as a control. Fourteen isozyme systems were tested, and the five having the best resolution selected: aspartate aminotransferase, esterases, alkaline phosphatase, glutamate dehydrogenase, and superoxide dismutase. These analyses confirmed the similarity between I. carneus and I. testaceus , since they both produced the same band patterns, which were in turn different from the band pattern of I. granulipolaris. So, as we couldn´t find any character wich permit us to classify the isolated studied during this work in defferent species, we believe that I. testaceus shoul be consider as a synonym of I. carneus .

Keywords : Fungi; Lodophanus; Isozymes; Synonymy; Taxonomy.
