Title: Morphological and Physiological Characterization of Three Groups in Coprinus comatus Species
Authors: L. Thomas and J. Labarere

Abstract:

The edible mushroom, Coprinus comatus, is a broad ill-defined species. Indeed, most taxonomists have described different subgroups within tins species, which they characterize from fruit body size, presence of a ring, deliquescence rate, gill colour and basidiospare measurements. The spedes C. comatus, C. sterquiTinus and C. ovatus were first gathered in the subgroup Comatl (Cooke M.C. 1871). Then, Ricken (1915) added the species C. clavatus to the classification proposed by COOKE, while C. sterquüinus was ruted out species or suteçecies related to C. comatus (Lendner A. 1920). Now taxonomists usually consider four subgroups: standard C. comatus, C. ovatus, C. clavatus and C. sphaerocephalus. Breeding Coprinus comatus, a cultivated mushroom, first required the previous morphological and physiological characterizafcion of the wild isolâtes and their assignment to the subspecies described. This is the oeason why our study aimed at characterizing 14 geographical isolates according the following criteria; aspect of the dikaryotic mycelia grown on culture media, morphology and physiotogy of fruit bodies, measurements of basidiospores (statistical analyse and viahility of basidiospones.
