Abstract:
An investigation examined the macro fungi population diversity together with their
morphology and ecological function distributed in the Eastern University grounds of
Sri Lanka. The metabolic processes of ecosystems depend heavily on macro fungi due
to their fruiting bodies which function as decomposers and symbionts and bio
indicating agents. The fungal diversity throughout Sri Lanka shows minimal
understanding which is especially true for the Eastern Province region. Researchers
collected 43 macro fungal specimens throughout different natural areas that
encompassed forests together with grasslands as well as dead organic materials.
Photographic records of the fungi included top, side and ventral perspectives while
morphological assessments concentrated on cap, stipe, veil & stalk morphology.
Technology used for identification included the observation of fungal spores under
the microscope to analyze their morphology and hyphal traits. The collected wet
specimens underwent preservation in IAo/o formalin for future reference while the
dried samples were sent for DNA barcoding to identify their taxonomic classification
through ITS region sequencing. Regular surveys recorded 41 fungal species that
belonged to 28 genera and 17 families throughout the university premises. The
research revealed three major fungal groups. Pycnoporus sanguineus and
Schizophyllum commune as saprotrophs arid Lctccaria laccata as a mycorrhizal
species as well as Marasmius spp decomposers. Adclitionally Galerina marginata was
recorded as toxic requiring proper identification. Researchers highlighted the
environmental functions of these fungi as they participate in nutrient processes and
biological decomposition and also form beneficial rtdationships with other organisms.
This study adds value to the Sri Lankan fungal biocliversity project by demonstrating
why protection of these organisms should be a priority particularly during ecological
degradation. The prepared specimen collection functions as an important educational
resource that enables future research on macro fungal ecology and economic
potential.
