Histological study of the discomycetes fungus cheilymina theleboloides

Abstract EN

A study carry out to study Habit and Habitat of Cheilymenia theleboloides (Discomycetes, Pezizales, Pyronemataceae) during January and February months.

Also, Histological study of apothecia structure by demonstrated in macro photographs and microphot ographs.

The results showed that the characters of macro and microstructure of the fungus confirmed that its Cheilymenia theleboloides.

Apothecia of this fungus were sessile scattered, gregarious on waste soil, medium to large size from 1-11 mm in diameter, first possessing concave discs and yellow to orange but become saucer to disc-shaped darkening to brown with age.

They are clothed with short comparatively few hairs.

The histological observation of apothecial sections consists three parts, the hymenium, the subhymenium and the excipullum.

The hymenium lines surfaces of the saucer or discoid shaped apothecial structures, coloration orangish-brown or yellow-to-orange.

It is made up of asci and paraphyses are arising from subhymenium.

The fleshy part of the ascocarp that supports by excipullum.

The excipullum consist of two parts : the ectal and medullary excipulum .

Apothecia begun to appear during January and February and continuous to 29 March.

The result showed that diameters of apothecia during January larger from February.

Most diameters of apothecia during February under 5 mm were 95 %, however diameters of apothecia during January under 5 mm were only 63 % and another diameters of apothecia more than 5 mm.

We found some variation for C.

theleboloides with several previous study, such as diameters and the shape of apothecia and apex of hairs in addition of the size of apothecium, asci, spores and the color and length of hairs.
