Hypocrealean lineages of industrial and phytopathological importance

This volume of Studies in Mycology is dedicated to Amy Y. Rossman, who published fundamental papers revising numerous genera and species in the Hypocreales. This title contains five contributions treating fungi in the families Hypocreaceae and Nectriaceae in the order Hypocreales. The plant pathogenic genus Calonectria represents a serious threat to the growth and sustainability of plantation forestry of Eucalyptus in both Brazil and Southeastern China. Both contributions treating Calonectria in this issue highlight the high species diversity in relatively small areas surveyed. A total of 38 novel Calonectria spp. (20 from Brazil and 18 from China) are introduced associated with a single genus, which in itself is very surprising. In Colombia, isolations from various Pinus species in plantations and nurseries displaying pitch canker disease symptoms resulted in the identification of more than 10 novel Fusarium species, five of which were provided with names. Pathogenicity results showed that two of the novel Fusarium taxa described, displayed levels of pathogenicity comparable to F. circinatum, therefore posing a new risk to commercial Pinus forestry in Colombia and other parts of t
