🔬 Morphology
Cap
Bulbous honey fungus
The cap of the bulbous honey fungus reaches 3 to 10 centimeters in diameter. When young it is convex-bell-shaped; with age it opens out to flat. The surface is covered with small, thin fibrous scales, especially in the center, and becomes smoother in wet weather. The color is yellowish brown, honey brown or ocher, darker in the center; the margin is paler, often with a reddish tinge. In dry weather the color fades noticeably.
Ringless honey fungus
The cap of ringless honey fungus is 3 to 8 centimeters across. When young it is convex-bell-shaped; with age it opens up to flat, sometimes with a small bump. The surface is covered with small, flattened scales, especially in the center. The color is honey yellow, ocher-reddish or yellowish brown, darker in the center. The honey color and scaliness make it resemble honey fungus, but the margin is often paler.
Hymenophore
Bulbous honey fungus
The hymenophore is gilled. The gills are whitish or cream, developing yellowish-reddish spots with age, attached to the stem or running slightly down it. The spore print is white. Pale gills that turn brownish with age, together with the weak cobwebby ring, help you recognize this species.
Ringless honey fungus
The hymenophore is gilled. The gills are whitish or cream, developing pinkish-brown spots with age; they are attached to the stem or run slightly down it. The spore print is white. Pale gills that turn brown with age, together with the absence of a ring on the stem, help you recognize this species.
Stem
Bulbous honey fungus
The stem is the most distinctive feature of the species: cylindrical, with a noticeably thickened, bulbous base, 5 to 12 centimeters tall. It is yellowish brown at the top and paler toward the bottom. The ring is weak, cobwebby-membranous, yellowish, and often disappears quickly, leaving only a fibrous band. It is precisely the swollen stem base that gave the mushroom its folk name, «thick-legged». There is no volva.
Ringless honey fungus
The stem is cylindrical, tapering toward the base, 5 to 12 centimeters tall, fibrous and tough. Its defining feature is the complete absence of the ring that honey fungus has; the stem is smooth along its entire length. It is yellowish at the top and reddish brown lower down, and several stems often grow fused together in a cluster at the base. There is no volva.
Flesh
Bulbous honey fungus
The flesh is whitish, rather thin in the cap and fibrous in the stem. It barely changes color when cut. Raw flesh tastes acrid, so the mushroom must always be thoroughly boiled before eating, after which the taste becomes mild. The quality of the flesh is somewhat lower than in honey fungus, so young caps are chosen for the table.
Ringless honey fungus
The flesh is white or cream, fairly thin in the cap and fibrous and tough in the stem. It barely changes color when cut. The taste is mild and pleasant, with no bitterness, but because the raw mushroom tends to cause digestive upset, it must always be boiled thoroughly before eating. Young caps are chosen for the table.
Smell
Bulbous honey fungus
The smell is faint, pleasant, somewhat sweetish, sometimes with a cheesy hint. The scent is not a defining feature, so for identification rely on the bulbous, swollen stem base, the weak cobwebby ring, the honey-colored scaly cap and its growth on the wood of broadleaf trees.
Ringless honey fungus
The smell is faint, pleasant and mushroomy, with no sharp notes. Aroma is not a defining feature, so for identification rely on the honey-colored scaly cap, the absence of a ring on the stem, growth in dense clusters on the roots of broadleaf trees and the late-summer-to-autumn season.
