[Differentiation of Amanita hemibapha (Berk. & Broome) Sacc. subsp. hemibapha and Amanita hemibapha var. ochracea Zhu L. Yang by Fourier transform infrared spectroscopy].

In order to demonstrate the ability of Fourier transform infrared (FTIR) spectroscopy for the differentiation of macro-fungi at variety level, FTIR spectroscopy was used to obtain vibrational spectra of Amanita hemibapha (Berk. & Broome) Sacc. subsp.

[Fourier transform infrared spectroscopic study of Coprinus comatus].

In the paper, Fourier transform infrared (FTIR) spectroscopy was used to study the fruiting body of wild growing and cultivated Coprinus comatus and the cap of the mushroom before and after deliquescing into inky liquid. The results show that the infrared spectra of Coprinus comatus are mainly composed of the absorption bands of protein and polysaccharide. Remarkable differences are observed in the absorption bands of polysaccharide between the spectra of the wild growing and cultivated mushrooms, by which the wild growing and cultivated Coprinus comatus can be discriminated.

[Fourier transform infrared spectroscopic study of truffles].

Truffles, which belong to ascomycetes, are rare wild growing edible mushrooms; their fruit body contains high nutritive value composition, and their polysaccharide constituents have potential medical applications. In the present paper, Fourier transform infrared (FTIR) spectroscopy was used for obtaining vibrational spectra of mushrooms of truffles growing in mountains of Yunnan province, southwest China. The results show that the mushrooms exhibit characteristic spectra.

[Fourier transform infrared spectroscopic study of different parts of wild growing edible mushrooms].

In this paper, vibrational spectra of different parts of fruiting bodies of wild growing mushrooms were recorded with Fourier transform infrared spectrometer. It was different for the spectra of cap skin, gill, cap meat and stem of the same mushroom. The great differences were found between cap skin and other parts of the same mushrooms of Russula virescens and Russula rubra, whereas the spectra of mushroom Termitomyces albuminosus show greated differences between gill and other parts.

[Identification of edible mushrooms by Fourier transform infrared spectroscopy].

In this paper, Fourier transform infrared spectroscopy (FTIR) was used to identify edible mushrooms belonging to Auriculariales, Aphyllophorales, and Agaricales of Basidiomycotina. Vibrational spectra of fruiting bodies of ten species belonging to nine different genera of mushrooms (one is cultivated, and the others are wild growing) were recorded. The spectra were divided into five regions, i.
