Various seeds, vegetable peels and fruits peels were used as substrates for the spawn production of different species of fungi namely: Auricularia auricula, Auricularia polytricha, Pleurotus sajor caju and Volvariella volvacea. The control substrates used in the spawn production weresorghum seeds for A, auricula, A. polytricha and P. sajor caju and tobacco midribs for V. volvacea. Evaluation was based on the observed mycelial thickness and the number of days complete mycelial ramification of the substrates. Mycelial thickness was categorized into evenly thick, evenly thin and unevenly thin. The difference in the rate of mycelial ramification in the control and the other substrates in the study was determined with the use of Students' t-test at 0.05 level of significance.In the spawn production of these fungi, there were mycelial growth in all the substrates. Evenly thick mycelial ramified in all the substrates used for the spawn production of A. auricula, A. polytricha, and P. sajor caju. While in V. volvacea, there were different mycelial thickness in each substrates.For the spawn production of A. auricula, calamansi seeds can be used as an alternative substrate because it supported mycelial growth which rate was statistically the same with that of sorghum seeds. For A. polytricha, mycelial growth rate in corn seeds and the combination of corn and papaya seeds (1:1) were statistically the same with the control. For P. sajor caju, malunggay and corn seeds supported mycelial growth which rates were statistically the same with that of sorghum seeds. For V. volvacea, taro peels supported growth which was similar to the growth in tobacco midribs.
