ABSTRACT
UNLABELLED The fungus Stachybotrys chartarum is the type species of the genus Stachybotrys. It is a cellulolytic saprophyte with a worldwide distribution and is frequently recovered in water-damaged buildings. Three isolates of S. chartarum were studied morphologically from single-spore isolations. Significant differences were found with the sizes, lengths, width, and L/W ratio of conidia and phialides among the isolates. QPCR analysis on S. chartarum, S. yunnanensis, S. chlorohalonata, S. elegans, S. microspora, and S. nephrospora showed that the primers and probe for detecting S. chartarum used by commercial laboratories were not able to differentiate S. chartarum from S. chlorohalonata and S. yunnanensis. Results suggested that S. chartarum may not be well delineated even after S. chlorohalonata was recently segregated from the species complex. Further study on the taxonomic status of the epithet S. chartarum is necessary. PRACTICAL IMPLICATIONS Six species of Stachybotrys are present indoors. Differentiation of Stachybotrys chartarum from S. chlorohalonata, and S. yunnanensis can be challenging using either morphological or QPCR methods. Caution should be taken to identify S. chartarum and closely related species and to explain their health effects implication for indoor air quality investigations.
