Abstract

 
Specimens of tooth fungi were collected from pine tree cones (Pinus sp.) in the Northern forests of Iran and transported to the laboratory for identification. The macroscopic characteristics of the samples were examined visually and microscopically using an Olympus BH2 microscope (Olympus, Japan).
The macroscopic features of the specimens were as follows: Fruit body hydnate-stipitate, pileus semicircular or kidney shape, broadly convex or flat, 1-3 cm across, covered with fine brown hairs. Hairs flexible when young, becoming tough and turning dark brown with age, growing singly or gregariously.
The underside of the pileus is covered with a crowded array of tiny tooth or needle-shaped spore-bearing structures or hymenium, up to 3 mm long, 0.5 mm diameter, initially whitish to cream, turning brown with age.
Stipe eccentric or lateral (attached to one edge of the pileus), 1.5 to 2 mm in diameter and up to 5 cm in length, tough, and covered with short fine hairs of the same color as the pileus.
Basidiospores broadly ellipsoid or globose, 4.5–5.5 × 4–5 µm, hyaline, smooth, or becoming finely spiny when mature, turning blue in Melzer’s reagent (amyloid). Spore print white.
The basidia four-spored with basal clamp connection, 15–24 × 3–4 μm. The hyphal system dimitic, comprising both generative and skeletal hyphae.
Specimens were identified as Auriscalpium vulgare Gray (Russulales, Auriscalpiaceae,) based on Koski-Kotiranta & Niemelä (1987) and Larsson & Larsson (2003). This is the first report of a species from the genus Auriscalpium Gray in Iran.
