Remarks (internal):The morphology is usually adequate for identification, but dried specimens of H. erinaceus may sometimes be difficult to separate from a compact form of H. alpestre, especially since the spore size is the same. In the Nordic material no such problems were encountered, because H. alpestre is not found there (see under H. coralloides); the species is easily distinguished from H. coralloides.

Description:Hericium erinaceus
Hydnum erinaceus Bull., Herb. France pl. 34, 1780: Fries, Syst. Mycol. 1: 407, 1821. - Hericium erinaceus (Bull.: Fr.) Pers., Mycol. Europ. 2: 153, 1825. - For synonyms, see Maas Geesteranus (1959). The specific name was used by Bulliard as a noun, which is therefore not inflected to agree with the gender of Hydnum. Many later authors have used in-correctly the adjectival form erinaceum (cf. Coker & Beers 1951).
Fruit body annual, globose, compact or sometimes lobed, up to 20 cm in diam. Whole fruit body white, yellow or with a fleshy tint, when dry ochraceous or red-brown. Upper surface with short, irregular, sterile spines. Hymenophoral spines on underside 2-3 (-5) cm long, regularly crowded. Stipe short and lateral, or nonexistent. Smell and taste fruity.
Section: Context homogeneous, soft when fresh and tough when dry, yellowish white, with cavitites. Context changing into trama without separating zone. Trama yellowish white, homogeneous.
Hyphal system monomitic. Generative hyphae 3-15 µm in diam, thick-walled, inflated, with amyloid walls and clamp connections, interwoven in the con-text and subparallel in the trama. Gloeoplerous hyphae 3-10 µm in diam, filled with oily matter, often bent like gloeocystidia into the hymenium. Basidia 30-40 x 5-7 µm, four-spored. Spores hyaline, minutely verrucose, 5-6 x 4-5 µm, fairly thick-walled, IKI blue, CB-.
