The Mycological Herbarium came into existence in 1992, although it contains collections made in 1990. The contents of the collection are primarily plant saprophytes and endophytes from Australasia and Asia. There are also significant numbers of voucher specimens from South Africa and South America present in the herbarium. However that number is expected to increase to approximately 8000 in the next year as members of the Fungal Biodiversity Project complete current projects.
Voucher specimens from the herbarium are available for loan to research institutes.
