Abstract

This study was conducted to list the different species of naturally occurring macrofungi in selected municipalities in Nueva Ecija, Philippines. The collected species were morphologically identified and recorded in terms of physical distribution, collection site, collection month, and climatic conditions. Opportunistic sampling was used to collect the wild mushrooms from May to July 2023 in four collection sites (San Isidro, Jaen, San Antonio, and San Leonardo). There are 53 collected fruiting bodies belonging to 2 phyla, 4 classes, 5 orders, 14 families, 21 genera, and 35 species taxa. Out of 35 species, 25 wild mushrooms were identified at their species level while 10 were identified at their genus level only. Two collected mushrooms belong to Pezizomycetes (5.71%) while the rest belong to Agaricomycetes (94.29%). The collected wild macrofungi grew solitary or gregarious in different substrates such as soil, trees, decaying logs or trunks of trees, and animal dung. Twenty-three (23) of the collected mushrooms were found to be edible, while 12 were poisonous. Site A (San Isidro) was recorded to have the highest percentage composition of macrofungi. The distribution of the macrofungi in the collection sites was found to be affected mainly by physical factors.

Abstract

Abstract. Bustillos RG. 2026. Growth and mycoremediation activity of Panaeolus antillarum on lead-contaminated coconut water media. Asian J Agric 10: g100104. https://doi.org/10.13057/asianjagric/g100104. This study investigated the mycoremediation potential of lead (Pb) using the coprophilous mushroom Panaeolus antillarum cultivated in solid and liquid coconut water media. Mycelial growth performance, including mycelial diameter, dry biomass, and volume loss, was evaluated under different Pb concentrations of 1 ppm, 10 ppm, 100 ppm, and 1000 ppm using coconut water gulaman as solid medium and coconut water as liquid medium. In addition, Pb accumulation in the mycelia was quantified to assess bioaccumulation capacity. Statistical analysis showed that the highest mycelial diameter and thickness were recorded at 1 ppm Pb (77.0 mm), which was not significantly different from the control without Pb (79.50 mm). In contrast, no substantial mycelial growth was observed at 1000 ppm Pb, indicating strong inhibitory effects at high metal concentration. Among all Pb-contaminated treatments, the 1 ppm medium produced the highest mycelial biomass (1.82 g) and volume loss (8.52 mL). Maximum Pb bioaccumulation was significantly recorded at 100 ppm (268 mg/kg), whereas lower accumulation capacity was observed at reduced Pb concentrations, particularly at 1 ppm (11.0 mg/kg). Notably, the detectable Pb content in mycelia grown at 1000 ppm was attributed mainly to passive adsorption rather than active uptake, as excessive Pb levels severely suppressed biomass production. Overall, the observed tolerance to Pb stress and the ability to accumulate Pb indicate that P. antillarum exhibits substantial heavy metal resistance and mycoaccumulation potential, supporting its applicability in mycoremediation strategies for Pb-contaminated substrates.
