We collected 24 samples of potentially infected Ash trees from Ashwellthorpe lower wood.
We used the PCR method of Gross et al (2012) to identify the H. pseudoalbidus MAT 1-1 (MAT1-1-3) and MAT 1-2 (MAT-1-2-1) mating types from these samples. The size of the PCR products indicated that five samples were of the MAT1-1 mating type and three were of the MAT1-2 mating type.
This confirms that both mating types are present within Ashwellthorpe lower wood.
