Abstract
A new species, Eupenicillium bovifimosum, was isolated from dry cow manure collected in Wyoming, USA. The outstanding morphological characteristics of this species are its robust, dense penicilli bearing long, broad columns of conidia, and its smooth-walled, unflanged ascospores which are produced within 3 wk of inoculation onto MEA. The new species produces penicillic acid, a fumagillin-like molecule, patulodin-like compounds CK2108A and CK2108B, and a compound resembling 2-[(2-hydroxypropionyl)amino]benzamide. Phylogenetic analysis using 1100 bases of the ITS and LSU DNA regions indicates that E. bovifimosum is most closely related to E. baarnense, and also to E. crustaceum, E. egyptiacum, and E. tularense.
The University of Wyoming Lab School provided the isolates of the new species and location information. The authors appreciate the help of Dr. Gregory K. Brown with SEM photography and Dr. Philip G. Holt with the Latin. Many thanks to Dr. Steve Peterson for making so many sequences available. The comments of two anonymous reviewers were very helpful for improving the manuscript. This research was supported in part by the National Science Foundation (grant # DEB-9632880), a NASA grant from the Wyoming Space Grant Consortium to the University of Wyoming Lab School (#NGT 5–40008), and the Danish Technical Research Council, Programme for Predictive Biotechnology.
