Sample collection and examination
One hundred and ten dead branches of Magnolia liliifera (ca
30 cm long, 1e2.5 cm diameter) that had fallen to the ground
under M. liliifera trees were collected and oven-dried at 70 C
for 1 week and used for the submersion and terrestrial
succession study. The submerged wood bait samples were
tied separately with nylon thread and submerged in the
study stream at Doi Suthep-Pui on 18 November 2002.
Twenty-five wood baits were randomly collected from the
stream at each sampling time along the stream of the study
site. It was planned to collect samples at 3, 6, 9 and 12
months. However, in the rainy season, most of the baits
were washed away by very strong flooding, while other baits
were buried in silt and sand. Therefore, baits were collected
only twice e 17 February 2003 (month 3; 25 samples) and 20
May 2003 (month 6; 25 samples). Sixty samples (ca 30 cm
long, 1e2.5 cm diameter) of naturally decaying M. liliifera,
that had fallen to the ground under the trees, were also
collected from areas alongside the stream for general fungal
diversity assessment. For terrestrial succession studies,
two-hundred living samples (ca 30 cm long, 1e2.5 cm
diameter, with bark) were cut and collected from living
trees. Samples were oven-dried at 70 C for 1 week and tied
