Hypocrealean fungi from a tropical rainforest in Queensland, Australia.

During a weeklong Mycoblitz in the Atherton Tablelands of Queensland, Australia, many hypocrealean fungi were collected. Preliminary identifications indicate that many of these specimens are part of the pantropical hypocrealean biota. Some of the common tropical species collected include: Bionectria subquaternata, Cosmospora vilior, Lanatonectria flavolanata, Nectria pseudotrichia, Neonectria jungneri, and Ophiotrichia trichospora. A number of interesting species of Neonectria were collected including N. pulcherimma, N. radicicola, and N. veuillotiana. Some lesser known species were also discovered. The unusual Hypomyces triseptatus was collected; this specie is known previously only from Africa and Asia suggesting that it may be a relict from the isolated forests. Viridispora alata was collected for the first time outside of the American tropics. Members of Haematonectria having Fusarium solani-like asexual states from Queensland had previously been determined to belong to clade 2 from South America and Asia. Although many of these specimens appear to be the common pantropical species, some data suggest that isolates of at least one species of Nectria from Australia-New Zealand represents a distinct lineage. Species of Cosmospora, Nectria and Neonectria will be investigated further.
