This one was difficult to sequence

Repeat regions caused serious enzyme slippage, making the sequence really hard to read. After careful review of the chromatogram, the closest BLAST match was http://www.ncbi.nlm.nih.gov/nucleotide/686694333 – confirming Morchella populiphila. I could probably get a clean sequence for most of the ITS region by sequencing the reverse strand of DNA, but I don’t think that’s necessary because the data I got was good enough for ID purposes.
