Descrizione della specie

Cappello

Elastico, irregolarmente imbutiforme, 3-10 cm di diametro, margine involuto, lobato; cuticola fulvo-rossastra od ocra-rossastra.

Tenace, rossastra.

• Odore: di anice.
• Sapore: tenue, mite.

Spore

Globose, amiloidi, bianche in massa.

Note

Come tutti i Lentinus ha le lamelle seghettate, caratteristica peculiare che lo distingue da altri funghi molto somiglianti.

Basidia (Basidia)

Lat. Basidia. A specialized structure of sexual reproduction in fungi, inherent only in Basidiomycetes. Basidia are terminal (end) elements of hyphae of various shapes and sizes, on which spores develop exogenously (outside).

Basidia are diverse in structure and method of attachment to hyphae.

According to the position relative to the axis of the hypha, to which they are attached, three types of basidia are distinguished:

Apical basidia are formed from the terminal cell of the hypha and are located parallel to its axis.

Pleurobasidia are formed from lateral processes and are located perpendicular to the axis of the hypha, which continues to grow and can form new processes with basidia.

Subasidia are formed from a lateral process, turned perpendicular to the axis of the hypha, which, after the formation of one basidium, stops its growth.

Based on morphology:

Holobasidia - unicellular basidia, not divided by septa (see Fig. A, D.).

Phragmobasidia are divided by transverse or vertical septa, usually into four cells (see Fig. B, C).

By type of development:

Heterobasidia consists of two parts - hypobasidia and epibasidia developing from it, with or without partitions (see Fig. C, B) (see Fig. D).

Homobasidia is not divided into hypo- and epibasidia and in all cases is considered holobasidia (Fig. A).

Basidia is the place of karyogamy, meiosis and the formation of basidiospores. Homobasidia, as a rule, is not functionally divided, and meiosis follows karyogamy in it. However, basidia can be divided into probasidia - the site of karyogamy and metabasidia - the site of meiosis. Probasidium is often a dormant spore, for example in rust fungi. In such cases, probazidia grows with metabasidia, in which meiosis occurs and on which basidiospores are formed (see Fig. E).

See Karyogamy, Meiosis, Gifa.

Amyloid (Amyloid structure)

The structure is called amyloid if from Melzer's reagent (solution of 0.5 g of crystalline iodine + 1.5 g of potassium iodide + 20 ml of chloral hydrate + 20 ml of distilled water) turns blue, violet, sometimes almost black.

See Dextrinoid structure.
