Speaking of ITS sequencing of types, here's a real dynamite study: Nagy et al New Phytol, in press (http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2011.03707.x...)
They sequenced a truckload of Mortierella types and HQ cultures and were able to explain a whole lot of the unidentified Mortierella sequences in GenBank. And there are certainly many of those. I maintain a list (http://www.emerencia.org/genuslist.html) of the top fungal genera in INSD as represented by unidentified ITS sequences there, and Mortierella has been on the top 10 for five years or more.
Type sequences. We love those.
Yes, that is good to see. Off topic, there is also a good paper by some of the same authors on evolutionary processes of fungal fruiting bodies in Systematic Biology.
Speaking of type sequences, we are finally working on including a 'type' field for future GenBank submissions.
The latest is that it was decided not to include a type modifier with GenBank accessions. The current field indicated as 'type' refers to something else, 'tissue type'.
So for now we are stuck using the notes field for this. Please consider adding your valuable epitype info as a note while we explore other possibilities to deal with this.
