**Key Features:**

* **Cap:** The cap is bright yellow-green with a rough texture, featuring short hairs that are slightly lighter than the cap's color.
* **Stem:** The stem is pale yellow to cream-colored, exhibiting a smooth texture. It appears to be slightly thicker at the base of the mushroom, tapering towards the top.
* **Gills:** The gills are decurrent, meaning they extend down the stem and form a skirt-like structure around it.
* **Spores:** The spore print is not visible in this image, but based on the description, it is likely white or cream-colored.
