It is also known by other names, such as the sharp-coned waxy cap or the yellow-stemmed waxcap. Its scientific name is derived from the Greek words hygro meaning "moisture," cybe meaning "head," and acuto meaning "sharp," and conica meaning "cone-shaped." While this mushroom may not have many synonyms in common usage, it is still a fascinating species that is worth studying for mushroom enthusiasts and researchers alike. Its bright yellow color and delicate appearance make it a striking addition to any forest or grassy area where it may be found.
