Taxonomic Classification: Pleurotus eryngii and white button mushrooms belong to different genera, Pleurotus and Agaricus
Pleurotus eryngii, commonly known as the king oyster mushroom, and the white button mushroom, scientifically referred to as *Agaricus bisporus*, are two distinct fungal species with significant differences in their taxonomic classification. The most fundamental distinction lies in their genera, as *Pleurotus eryngii* belongs to the genus *Pleurotus*, while the white button mushroom is classified under the genus *Agaricus*. This separation at the generic level indicates that these mushrooms are not closely related and have evolved along different evolutionary pathways within the fungal kingdom.
Within the broader taxonomic hierarchy, both genera fall under the family Agaricaceae in the order Agaricales, but this shared classification at higher levels does not imply similarity at the species or genus level. The genus *Pleurotus* is characterized by its gilled mushrooms that typically grow on wood, with species often referred to as "oyster mushrooms" due to their shape and habitat. In contrast, the genus *Agaricus* includes mushrooms that are commonly found in grassy areas and are known for their robust, fleshy caps and gills that change color as they mature. These morphological and ecological differences reflect their distinct evolutionary histories.
The species *Pleurotus eryngii* is further distinguished by its unique substrate preferences, often growing on the roots of herbaceous plants like *Eryngium* (thistles), whereas *Agaricus bisporus* is a saprotrophic fungus commonly found in composted soil or manure. This difference in habitat and substrate utilization underscores their taxonomic separation. Additionally, molecular studies have confirmed genetic disparities between the two genera, reinforcing their classification as unrelated taxa despite superficial similarities in appearance.
From a culinary perspective, the taxonomic distinction is also reflected in their texture, flavor, and usage. *Pleurotus eryngii* has a meaty texture and is often used as a meat substitute, while *Agaricus bisporus* has a milder flavor and is more commonly consumed in its button, cremini, or portobello forms. These differences are rooted in their biological and evolutionary divergence, highlighting the importance of accurate taxonomic classification in understanding fungal diversity.
In summary, while both *Pleurotus eryngii* and white button mushrooms are edible fungi belonging to the same order, their taxonomic classification clearly places them in different genera—*Pleurotus* and *Agaricus*, respectively. This distinction is supported by morphological, ecological, genetic, and culinary differences, making it evident that they are not the same species or even closely related within the fungal kingdom. Understanding this taxonomic separation is crucial for accurate identification, cultivation, and utilization of these mushrooms.

Appearance Differences: Pleurotus eryngii has a thicker stem and smaller cap compared to white buttons
When comparing the appearance of Pleurotus eryngii (also known as king oyster mushroom) to white button mushrooms, one of the most noticeable differences lies in the stem and cap proportions. Pleurotus eryngii boasts a significantly thicker stem, which is not only more robust but also denser in texture compared to the slender and delicate stem of a white button mushroom. This thickness contributes to its meaty and substantial feel, making it a favorite in culinary applications where a hearty mushroom is desired. In contrast, the stem of a white button mushroom is notably thinner and more delicate, often blending seamlessly with the cap in terms of texture and presence.
The cap size is another distinguishing feature between these two mushrooms. Pleurotus eryngii typically has a smaller cap relative to its stem, creating a more elongated and cylindrical appearance overall. The cap is usually compact and rounded, with a smooth surface that may have subtle ridges or patterns depending on maturity. White button mushrooms, on the other hand, present a larger cap that dominates their structure, giving them a more rounded and bulbous shape. The cap of a white button mushroom is often more open and flatter, with a surface that can range from smooth to slightly flaky, especially as it ages.
Coloration also plays a role in their appearance differences, though it is secondary to the stem and cap proportions. Pleurotus eryngii generally has a lighter to medium brown cap, while its stem is often a pale grayish-brown. The color contrast between the cap and stem is usually subtle. White button mushrooms, true to their name, are predominantly white or very light beige, with minimal color variation between the cap and stem. This uniformity in color, combined with their larger cap size, makes white button mushrooms easily recognizable and distinct from the more elongated and bicolor profile of Pleurotus eryngii.
Texture and surface details further highlight the appearance differences. The cap of Pleurotus eryngii is smoother and firmer, with a surface that feels almost velvety when young. As it matures, the cap may develop fine cracks or lines, but it retains its compact nature. White button mushrooms have a more delicate cap texture, which can become slightly dry or flaky as they age. Their surface often exhibits more pronounced gills underneath, which are less apparent in the smaller, tighter cap of Pleurotus eryngii. These textural and structural differences make it easy to distinguish between the two mushrooms at a glance.
In summary, the appearance differences between Pleurotus eryngii and white button mushrooms are primarily defined by the thicker stem and smaller cap of the former. While both mushrooms share a similar earthy tone, the king oyster mushroom's elongated, cylindrical shape and denser stem contrast sharply with the white button mushroom's larger, flatter cap and slender stem. These distinctions are not only visually apparent but also influence their culinary uses, with Pleurotus eryngii often favored for its meaty texture and white buttons prized for their delicate, versatile nature. Understanding these appearance differences ensures accurate identification and appropriate use in cooking and other applications.
