Morphological Features:
Pileus whose diameter in the adult stage can exceed 5 cm, but it is uncommon for it to reach 10. In its initial growth stage, it has a globose shape, but soon becomes convex and finally plane-convex; only very old specimens may flatten out. Its surface is yellowish-ochre in the central area, fading toward the margin to more sulphur-yellow tones; it is smooth and glabrous. Margin incurved to straight, fairly regular; young specimens often bear remnants of the veil on it, which tend to disappear rapidly due to rain.
Lamellae adnate and very crowded; pale in color initially, but adopting a greenish hue that prevails for much of their development. Finally, due to sporulation, they turn purplish-brown.
Stipe cylindrical and very elongated; when growing fasciculate, it is typically curved. It is hollow and yellowish, darkening with age, and generally bears remnants of a whitish or yellowish partial veil upon which spores are deposited upon maturity, staining it purplish-brown.
Flesh thin and yellowish, with an elastic consistency, especially in the stipe, which is highly flexible due to this trait. Its odor is complex but quite unpleasant, and its taste is intensely bitter; this bitterness would even persist after prolonged, hypothetical cooking.
Habitat:
It is one of the most frequent and abundant species in our forests, where it grows fasciculate, invariably attached to stumps or roots of various trees, without special preference for any particular type of woodland. Although it fruits most profusely in autumn, it can practically be found throughout the year.
Observations:
This species causes gastrointestinal disturbances, but poisoning from this mushroom is highly unlikely due to its intense bitterness, which persists even if mistakenly cooked. It bears a notable resemblance to Hypholoma capnoides, which also grows fasciculate; however, the latter has white and sweet flesh, and its lamellae are not green but greyish. Hypholoma lateritium has a brick-red color in the center of the pileus.
