Abstract
Ubiquinone profiles of 25 strains ofTalaromyces were determined using reversed-phase high performance liquid chromatography. Together with data of earlier authors, examination of the most recently described species allowed us to solve some taxonomic problems in the intrageneric classification. Ubiquinone Q-10(H2) was found in the majority ofTalaromyces species with aPenicillium anamorph, which are mostly placed in seriesFlavi andLutei of sectionTalaromyces. Flavi andLutei are closely related and homogeneous taxa based on their morphological characters used in the section. However, exceptionol prfiles were consistently shown byT. trachyspermus and the allied taxa of seriesTrachyspermi of the sectionTalaromyces, in which a mixture of ubiquinone Q-10(H2) and ubiquinone Q-10(H4) was found. Thus the accommodation ofT. trachyspermus and the allied taxa in the sectionTalaromyces was not supported by their ubiquinone systems.Trachyspermi is distinguished from other taxa ofTalaromyces by its production of white ascomata and rapid growth at 37°C. A new section,Trachyspermus, is proposed herein. SectionEmersonii showed heterogeneity; the ubiquinone profiles (Q-10(H2) or Q-10 and Q-10(H2)) inTalaromyces with aGeosmithia anamorph were relatively homogeneous, whereas those of another group with aPaecilomyces anamorph were considerably variable. OnlyTalaromyces with aGeosmithia anamorph can be placed in the sectionEmersonii.
