A small tissue from the flesh section between the pil- eus and stipe of fruit body was cut with a sterilized knife and placed into a 1.5 ml centrifuge tube containing 300 μl 2X CTAB buffer and kept in −20°C for DNA extrac- tion. The specimens were ground with 200 mg of steril- ized quartz sand then 2X CTAB extraction buffer were added for adjusted to 600 μl. Contents were then incu- bated at 60°C in a water bath for 30 min with gentle swirling. The solution was then extracted two or three times with an equal volume of chloroform: isoamyl (24:1) at 13,000 rpm for 30 min until no interface was visible. The supernatant phase containing the DNA was precipi- tated by addition of 2.5 volumes of absolute ethanol and kept at −20°C overnight. The DNA pellet was washed (70% ethanol) 2 times, dries (under vacuum), and resus- pended in TE buffer (1 mM EDTE, 10 mM Tris-HCL, pH 8) and mixed together with RNase A (1 mg/ml−1). In addition some tissues specimens were extracted for DNA by using DNA extract Kits (NucleoSpin® Plant II, Ma- cherey Nagel, Catalog no, 740770.50) following manu- faturer’s protocal.
