Sri Lanka being one of the 34-biodiversity hotspots in the world bearing a tremendous variety in flora and fauna and it will hold true for fungal species selection as well. In Sri Lanka, warm wet timeless rain forest supplies, mainly Sinharaja forest is well examined for the macro and micro yeast diversity. Yet , studies inside the dry zone and more advanced zone forests are neglected though 83% of the country’s forest cover belongs to this category. In trying describing the decaying solid wood associated fungal diversity in a dry mixed evergreen forest reserve the present study was initiated. Decaying wood examples were accumulated from Dimbulagala forest book.

Decaying hard wood items of at least 6 in . length had been collected arbitrarily. Fungal stresses associated with the decaying woods had been isolated into PDA or perhaps semi selective medium and pure civilizations were received. Macroscopic and microscopic features were discovered. Total genomic DNA was isolated via modified CTAB method and Polymerase String Reaction (PCR) was executed targeting rDNA-ITS region using universal IT IS primers and Sanger dideoxy sequencing was carried out to look for the nucleotide collection of the place. Sequences had been manually edited and compared to the GenBank using Fundamental Local Series Alignment Search Tool (BLAST).

Phylogenetic relationships between decaying solid wood associated fungus were identified using HUGE (version six. 0). Fungal cultures were maintained with the Department of Botany employing dry filtering papers in addition to sterilized unadulterated water. A total of fifty-five fungal isolates were obtained from 36 decaying wood parts and 35 fungal species were successfully identified. Benefits indicated that Sri Lankan dry merged evergreen woodlands are rich in species of Paecilomyces, Daldinia, Trametes, Perenniporia, Phanerochaete, Hypoxylon, Schizophyllum, Lentinus, Fusarium, Coriolopsis, Phlebia, Coprinellus, Gymnopilus, Scytalidium, Trichoderma, Xylogone, Lasiodiplodia, Neoscytalidium and Pleurostoma.

Species of Trichoderma and Lasiodiplodia were the most abundant varieties. T. harzianum T. lixii, T. longibrachiatum, and T. erinaceus were found. Away of 6 Lasiodiplodia isolates, three had been L. crassispora, and the snooze were hailed from the species of L. pseudotheobromae, L. theobromae, and M. pseudotheobromae. A few of the isolated fungus were already known flower pathogens and a few were famous bio degraders. Results mentioned that least studied Sri Lankan dried out mixed timeless forests happen to be rich in different fungal varieties and could serve as another source in finding biotechnologically important yeast species.
