Fruiting body of sulfur yellow hypocrea:

At first, it manifests itself in the form of matte fragments on the fruiting body of the glandular exsidia, Exidia glandulosa; over time, the fragments grow, harden, acquiring a characteristic sulfur yellow color, and merge into a single conglomerate. Sizes can vary significantly depending on growing conditions; in the final stage of development, the size of sulfur-yellow hypocrea can be up to ten or more centimeters. The surface is hilly, wavy, abundantly covered with dark dots – the mouths of perithecia. That is, in other words, directly the fruiting bodies of the fungus, in which, accordingly, spores are formed.

The flesh of the body of hypocrea is sulfur-yellow:

Dense, nostrilous, yellow or yellowish.

Sory powder:

Lanu paʻepaʻe.

Faʻasalalau:

Hypocrea sulfur yellow Trichoderma sulphureum occurs somewhere from the middle or end of June to the middle or end of September (that is, throughout the warm and more or less wet season), spurring glandular exsidia in places of its traditional growth – on the damp remains of deciduous trees. It can grow without visible signs of the host fungus.

Ituaiga tutusa:

The genus Hypocrea contains several more more or less similar species, among which Hypocrea citrina stands out in a special way – the mushroom is rather yellowish, and it does not grow quite in those places. The rest are even less similar.

Mea'ai:

The fungus itself feeds on mushrooms, there is no place for a person here.
