1. Cap:

Cap is the top part of your little yellow mushroom. It looks just like an umbrella and gives the same function, i.e., protection.

Cap protects the gills and seeds and cannot be seen without a microscope.

o Size:

From a baby fungus till it gets mature,

Leucocoprinus Birnbaumii can size between 2.5 to 5 centimeters.

o Color:

As it is called a yellow Dapperling, so of course, it appears yellow.

It has bright yellow color as a baby while mature Dapperling becomes pale yellow, but not with a brown center.

The brown-centered yellow Dapperling is Leucocoprinus flavescens.

o Shape:

The shape of the cape is more oval (egg-like) when it is young.

When mature, the shape becomes broadly conical, convex, or more like a bell.

o Texture:

The texture of the cap has fine scales on it.

A margin line appears on the center till maturity.

2. Lamella:

Lamella, also called mushroom gills, is a rib-like papery hymenophore under the cape of mushrooms.

It is not present in all mushrooms but can be seen in the Leucocoprinus Birnbaumii.

Lamella of Leucocoprinus Birnbaumii is free from the stem, has short yet frequent gills, with recurring patterns.

They can have a bright yellow to pale yellow color.

The mushroom stem is mainly used in cuisines because, more often, it is non-toxic.

However, that’s not the case with this flowerpot parasol.

Height x width.

This yellow houseplant mushroom has 3 – 10 cm length while 2–5 mm width or thickness.

From the base, the stem is even thicker, which gives a swollen feel.

However, it doesn’t have spores or gills; it is bald.

You can also see a fragile yellow ring on it that keeps appearing and disappearing.

Trama is also called flesh because of the fleshy portion inside the mushroom fruit body.

Here is what you need to know about the yellow mushroom flesh.
