Some morphological characteristics were studied. Strain A. 27 of A. bitorquis produced white dikaryotic colonies. Clamp connection and chlamydospores were absent in hyaline mycelia. White besidiocarps of A. 27 consisted of short thick stipes with single ring and without volva. Pileus was convex and later became shallowly depressed in the middle. The width of the pileus varied from 4.0 to 9.0 cm, the stipes also varied from 4.1 to 9.0 cm in size and from 0.6 to 2.3 cm in length. Basidia were formed in hymenial layer on lamellae, each one produced 4 basidiospores on top of an individual short sterigma. The development of basidiocarps was Angiocarpic-agaricus type.
