Adnate

Adnate mushroom gills are broadly attached to the stalk slightly above the bottom of the gill, with most of the gill fused to the stem.

An anther is adnate when fixed by its whole length to the filament.

The ovary is more adnate to the calyx than in any other species of the genus.

Morphologically and chemically X. isidiigera is also similar to X. australasica, but the isidia are typically thinner and more coralloid branched and the thallus more adnate in the latter species.

Morphologically, Hypotrachyna kriegeri closely resembles more adnate morphotypes of H. imbricatula.

It differs from N. eleutherus by possessing a more adnate adipose fin and more prominent saddles and from N. albater by having 8 soft pectoral rays, a submarginal adipose bar, and no prominent basicaudal bar (Douglas 1972).
