Abstract
Fungi comprise one of the most diverse groups of eukaryotes with many cryptic species that are difficult to identify. In this chapter, we detail a protocol for the molecular identification of the most industrially relevant species of Trichoderma—T. reesei. We first describe how a single spore culture should be isolated and used for the sequencing of the diagnostic fragment of the tef1 gene. Then, we provide two alternative methods that can be used for molecular identification and offer the diagnostic oligonucleotide hallmark of the tef1 sequence that is present in sequences of all T. reesei strains known to date and that is therefore suitable for reliable and straightforward identification.
