Page number:58 
Remarks (internal):A. vulgare is easily identified by its growth on cones and unmistakable appearance. The colour of the fruit body and the hairiness of the cap vary with the age. Old pilei tend to be dark cigar brown and almost glabrous, while young ones are light chestnut brown and covered with bristles. The size variation is very small. According to the literature, the diameter of the pileus is 0.5-2 cm (Nikolaeva 1961, Maas Geesteranus 1971, Phillips 1981, Jülich 1984, Ryman & HolmÃ¥sen 1984), which fits well with our measurements. However, according to Phillips (1981) and Jülich (1984), the length of the stipe is up to 140 mm, which is over twice as long as in the Fennoscandian material.

Description:Auriscalpium vulgare
Hydnum auriscalpium L., Species Pl. 2: 1178, 1753: Fries, Syst. Mycol. 1: 406, 1821. - Auriscalpium vulgare S.F. Gray, Nat. An. British Pl. 1: 650, 1821. - For typification and synonyms, see Maas Geesteranus (1959).
Fruit body annual, stipitate or occasionally several fruit bodies arising from a common base, fibrous when fresh, hard when dry. Pileus 0.5-2 cm across, round or kidney-shaped, piano-convex, covered with bristles, glabrescent with age, dark chestnut brown. Margin entire, when old inrolled and often wavy. Spines up to 3 mm long, cylindrical down to the base, acute, light brown when young, later covered with a white spore mass and then ashy grey. Stipe 14-55 mm long, 1-2 mm in diam, laterally attached to the pileus, cylindrical or slightly flattened, with a bulbous base, hirsute, fibrillose, dark chestnut brown. No specific taste or smell.
Section: Context up to 0.5 mm thick, duplex with thin, darker hairy layer and thick, rather soft, fibril-lose, ochraceous, lower context. Cortical layer thin, black-brown, compact. Stipe layered, with thin dark cortex, covered by hairs, encircling the inner ochraceous context proper.
Hyphal system dimitic. Generative hyphae thin-walled, 1.7-4 µm wide in diam, hyaline, with clamp connections. Skeletal hyphae 1.5-4.8 µm in diam, thick-walled. Bristles made up of 2.5-4 µm wide, rarely clamped, secondarily septate, branchless, parallel, agglutinated generative hyphae, which are hyaline at the tip, turning brown towards the base. Cortex with 2-4 µm wide, brown, thick-walled, parallel, agglutinated, frequently clamped, branchless generative hyphae. Context proper with interwoven generative and skeletal hyphae. Cortex and context proper of the stipe similar to cortex of the pileus; change from context to trama continuous. Trama with subparallel generative and skeletal hyphae. Gloeoplerous hyphae 3-5 m in diam, with oily contents, protruding into the hymenium as club-like or sharp-pointed gloeocystidia. Basidia 15-24 x 3-4 µm, with basal clamp, four-spored. Sterigmata 3 µm long, swollen at the base. Spores ellipsoid, hyaline, minutely verrucose, 4-7 x 4-5 µm, IKI blue, CB-.
