These diseases occur widely in temperate and tropical regions, however, the sexual states of these fungi often occur only in the tropics. In order to know the complete life history of these fungi, tropical species must be studied. This paper presents an overview of the tropical members of the Hypocreales including both their sexual and asexual states. A key for identification to genus is provided as well as a table to the major monographic accounts of tropical hypocrealean fungi. This publication will be used by those seeking to identify these fungi as well as to develop strategies for control of diseases caused by these fungi through crop management and plant breeding. Technical Abstract: The ascomycete order Hypocreales (pyrenomycetes) includes about eighty genera, most of which are either primarily or exclusively tropical. The order is characterized by lightly to brightly colored perithecioid ascomata, a hamathecium of apical paraphyses that largely disintegrate at maturity, unitunicate asci, hyaline ascospores, and moniliaceous anamorphs that typically have phialides and conidia held in lightly to brightly colored slime. The most frequently encountered genera in the order are discussed. A key to the most common genera and species groups is included. |
