GC (NCBI Gene Bank Accession no&amp;nbsp;GQ369961) associated with the roots of an epiphytic orchid &lt;em&gt;Gastrochilus calceolaris&lt;/em&gt; was&amp;nbsp;investigated by cultural morphology, microscopic features and molecular analysis of&amp;nbsp;Internal Transcribed Spacer (ITS) regions sequences of nuclear ribosomal DNA. The&amp;nbsp;colony appearance of the fungal endophyte was fluffy growth pattern and the colour of&amp;nbsp;the young colony was milky white on both surfaces that turned in to brown at maturity on&amp;nbsp;the upper surface and deep brown on reverse surface. The microscopic features of the&amp;nbsp;fungus i.e. hyphal diameter, multi-nucleate vegetative cells, right angle branching pattern&amp;nbsp;with slight constriction at branching point and a dolipore septum near the branching point&amp;nbsp;were observed. All the characters corroborated the identity with anamorphic &lt;em&gt;Rhizoctonia&amp;nbsp;&lt;/em&gt;like fungi. The ITS regions sequences of nrDNA and phylogenetic analysis based on the&amp;nbsp;neighbor-joining method showed clustered with &lt;em&gt;Rhizoctonia&lt;/em&gt; like fungi, and the&amp;nbsp;maximum identity (98.28%) with &lt;em&gt;Ceratobasidium&lt;/em&gt; RR and &lt;em&gt;Ceratobasidium&lt;/em&gt; FPUB&amp;nbsp;isolated from &lt;em&gt;Rhynchostylis retusa&lt;/em&gt; and &lt;em&gt;Dactylorrhiza hetagera&lt;/em&gt;, respectively. Thus, the&amp;nbsp;ITS of nrDNA sequences validated the morphological data. This is the first report of&amp;nbsp;orchid mycorrhizal fungi from Bangladesh.&lt;/p&gt;}, number={2}, journal={Bangladesh Journal of Plant Taxonomy}, author={Hossain, Mohammad Musharof}, year={2019}, month={Dec.}, pages={249–257} }
