Endophytic fungi from Cassia fistula or golden shower, a well known medicinal plant in Thailand and Asia, were isolated from trees growing in three geographical separate sites. These locations were Kanchanaburi, Nakhon Ratchasima and Bangkok and were selected to allow comparisons between their endophytic assemblages and to evaluate these data in relation to differences in plant diversity and density and local environment. Kanchanaburi which was the site closest to a natural forest situation provided the highest number of isolates with Bangkok, where the trees were isolated individuals, having the least. Members of the Xylariaceae proved to be common and frequent isolates especially species of Xylaria and Daldinia but Nemania and Hypoxylon were also obtained. Phomopsis was also well represented and clearly was dominant at the Kanchanaburi site. Species of Fusarium, Colletotrichum, Penicillium, Nigrospora, Coprinus and Psathyrella were also identified but were occasional isolates. Differences in endophytic assemblages between samples obtained early in the rainy season (July, 2001) with those sampled towards the end of the rainy season (December, 2001) were found to occur in the Nakhon Ratchasima samples with over twice as many isolates obtained from the December samples. This is likely to be a reflection on the longer exposure period to the potential inoculum of these leaves. A total of 956 endophytic isolates were obtained from the three sites with samples from Kanchanaburi (D...
