Tricholoma davisiae Peck Bull.

 トガリシメジ(仮称）

 This species has been shown as Tricholoma sp.2 on my web.  Lately Mr. Bill Neill, New England, USA write me that this will be T. davisiae which is an American species with acute umbonate pileus and greenish fruit body. T. davisiae also has cylindrical cheilocystidia, colorless, consisted from several cells. The spore size of T. davisiae is 6.7-7.6 x 4.3-5.2 micro meter. Although, this species has dark color cheilocystidia(below right) against colorless one of T. davisiae, and has a little larger spores(below left),  many characters are almost identical and I concluded this as T. daviciae or very close species of it.

8-9.5 x 5-7 micro meter
