INTRODUCTION
There are several edible well known mushrooms naturally growing in the dry Dipterocarp forest at the Phuphan National Park whilst a few types are poisonous.Most of the mushrooms are in the Actomycorrhizal family which growing as saprobes and parasites.[1] Ectomycorrhizal fungi (ECM) are vital component of forest biodiversity and play a part in forest restoration.Those in the symbiotic type which growing around many plants' roots provide water, minerals to their host plants, moreover, they help protect the hosts from many pathogens.Up until now, there are still less studies on mushroom 2.5.DNA Extraction morphological characters which are inadequate to obviously classify types of mushrooms, so molecular techniques studies are needed to classify mushrooms' species, those of the Amanita and Boletus families in particularly.
As the result, it remains less explanation and knowledge about mushrooms made published, whether it be the relationship between mushrooms and other plants, the physical factors are favourable to mushrooms' growth, and etc.

Collecting Sites
The mushrooms were collected from Phuphan National Park village forest in Sakon Nakhon Province.The site was in Dry Diptercarp forest.

Collecting Methods
The samples were collected randomly from every stage of ages in two experimental areas sized 100  100 m 2 and 1000  10 m 2 during January-December in 2008-2009.Young mature and old individual fruiting bodies were collected with chisel soil were removed with a fine brush and placed in brown paper bags in a basket, while data of associated host, temperature humidity and intensity of light at the study were recorded.The mushroom collected in study sites and roadside markets nearby the study sites were noted and some interest species were also bought for examination.The tissue of all specimens was kept in 1.5 ml microcentrifuge tube poured in 300 µl 2X CTAB buffer at −20˚C.Specimens were dried at 45˚C -50˚C overnight and kept in plastic boxes with silica gel to keep out humidity.

Taxonomy Methods
The mushrooms were tentatively identified by a conventional morphology method presented by [1,2] and chemical methods using the keys that provided by [3][4][5] was employed to classify their chemical characteristics.The latter method was used as the main way to assemble mushrooms in the Basidiocarp family, physical features and basidiospore.

Culture and Edibility Information of Some Edible and Wild Boletes
The fresh sporocarps of mushroom especially the edible species were cultured for vegetative mycelium.A pure culture of each collection was isolated from the issue (small pieces that cut from section between the pileus and strip) using half strength Potato Dextrose Ager (PDA) plate.The pure culture was incubated at room temperature (28˚C ± 2˚C) [6].
A small tissue from the flesh section between the pileus 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 extraction.The specimens were ground with 200 mg of sterilized quartz sand then 2X CTAB extraction buffer were added for adjusted to 600 µl.Contents were then incubated 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 precipitated 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 resuspended 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, Macherey Nagel, Catalog no, 740770.50)following manufaturer's protocal.
Genomic DNA 3 µl was used in a standard 50 µM PCR mixture (25 mM MgCl 2 , 10 MG-free buffer, 2.5 µM dNTPs, 1.5 µM primers, and 1.5 unit of Taq DNA Polymerase-BioLabs M0267-S) under the following thermal condition: 94˚C for 30 s, 35 cycles of 94˚C for 30 s, 60˚C for 30 s, and 72˚C for 1.5 min.Amplicons were checked on 1% agarose gels stained with ethidium bromide under UV light.Negative control reaction omiting DNA were included in all sets of amplifications to monitor potential contamination by exogenous DNA.PCR products were purified using NecleoSpin ® Extract II PCR clean-up Kit (Macherey Nagel, Catalog no.740609.50)following manufacturer's protocol.Te amplified 28S rDNA and ITSs fragments were directly sequenced.Sequencing reaction was performed and sequences determined automatically by Macrogen Company in Korea using PCR primer mentioned upper part.because of their major roles in natural and managed ecosystems as ectomycorrhizal fungi.The fungal group becomes an important factor for reforestation program worldwide.Furthermore, they are important as food source for human beings and animals [9].In addition fungal diversity as well as mushroom can also be used as a bio-indicator of environmental quality.Studies on the diversity and taxonomy (base on morphological characters and molecular analyses) of mushroom and other macro and other macro-fungi of Thailand are interested and need more investigation.

Knowledge of Mushroom diversity is important
This study aims to complete the study of diversity and molecular relations of some stripe-tubulate mushroom collected from reserved rainforest in The Phuphan National Park, Sakhon Nakhon Province.

Diversity of Mushroom in Phuphan National Park, Sakhon Nakhon Province
The result of this study provided overviews of the diversity and molecular phylogeny of ectomycorrhizal mushroom in The Phuphan National Park, Sakhon Nak-hon Province.Approxmimately 34 collections were recorded in The Phuphan National Park, Sakhon Nakhon Province over a two-year period from 2008 to 2009 during wet and cool dry season (January to November).Species classifications and distribution of the identified mushroom present in Table 1.
The study found that the first, there are a variety of mushrooms in dry dipterocarp forest on 2008-2009 at Phuphan national park, found 34 species in total.There were 26 types found in both years Amanita hemibapha subsp.javanica  ) Fr.The mushrooms that had been found had significantly relations to the surrounding physical conditions, 22 species were found at the temperature range 29˚C -30˚C (min 28˚C, max 31˚C, average 29˚C) as shown in Figure 1(a), most mushrooms (28 species) were found at the relative humidity range between 68% -96% (min 54%, max 96%, the average relative 75%) as shown in Figure 1(b), 26 species found at pH range 7.0 -7.9 (min 6, max 8.9, average 7) as shown in Figure 1(c), and 16 species found at the light intensity range of 150 -500 lux (min 150, max 1800, average 970) as shown in Figure 1(d).
The third, by using the BLASTN computer programme to examine, compare and separate the differences 4 types of mushrooms' DNA in the Amanitaceae and the Boletaceae families subjected to the PCR method, there were 4 findings i.e. 1342 DNAs bp. of Amanita princeps, 880 DNAs pb. of Boletus nobitis Peck, 1381 DNAs pb. of Boletus edulis Bull.ex Fr and 758 DNAs bp. of Heimiella resipora (Pat & Baker).The modern science can effectively identify types of mushrooms of the Amanita family as well as the difference levels of the molecule of each type of mushrooms [10][11][12][13][14][15][16].
