*3.4. Mechanical Testing*

The mechanical testing served to compare the effects of three main variables on the biocomposite material's properties: fungal species (*Pleurotus ostreatus* and *Coprinus comatus*), substrate particle sizes (with or without micro-particles), and post-growth treatment (dried, baked, compacted then dried, and compacted then baked). The acronyms given to each sample are shown in Table 1.
