Clavulinopsis helvola

Morphological Features:

Fruiting body formed by a simple, unbranched structure in the shape of an erect thread, or flattened club-shaped in adult specimens. No visual differentiation is apparent between the sterile basal zone and the fertile portion. Its color ranges from yellow to pale orange or egg-yolk yellow; we have observed that specimens more exposed to sunlight are more orange than those hidden among the grass, which are distinctly yellow. The apex is concolorous and rounded.

Hymenium embedded within the pileipellis of the fruiting body, occupying the upper two-thirds thereof; only the base is sterile.

Stipe absent as such.

Flesh firmer than that of related species, even fibrous; the fruiting body is solid throughout. It lacks a noticeable odor and has a sweet, mild taste.

Habitat:

This fungus appears throughout autumn, fruiting in grasslands and herbaceous areas. It is a rare species, difficult to locate, which furthermore camouflages very well among the grass.

Observations:

This is a species that requires appropriate microscopic analysis for accurate classification. Its spores, bearing thick warts, allow for definitive identification. It closely resembles Clavulinopsis laeticolor, which has spores lacking warts and a lateral apiculus. It also resembles Clavulinopsis luteoalba, which has smooth, elliptical spores. A variety of this species exists, var. geoglossoides, which is less slender and longitudinally grooved.
