Page number:52 
Remarks (internal):Externally, C. cirrhatus can be confused with small specimens of Climacodon septentrionalis, but the former has a soft, spongy texture, while the latter has a tough fibrous context. In the microscope C. cirrhatus is identifiable by its amyloid spores and gloeocystidia, while C. septentrionalis has nonamyloid spores and thick-walled, oil-free cystidia. The genus Creolophus is separated from Hericium by the smooth spores and nonamyloid contextual hyphae. The ontogeny of the growing basidiocarp and the microscopical changes that it undergoes during maturation have been described by Maas Geesteranus (1962).

Description:Creolophus cirrhatus
Hydnum cirrhatum Pers., Syn. Meth. Fung.: 558, 1801: Fries Syst. Mycol. 1: 411, 1821. - Creolophus cirrhatus (Pers.: Fr.) Karst., Medd. Soc. Fauna Flora Fennica 5: 42, 1879. - Typus: not designated, no original collection found in herb. Persoon (L).
Fruit body annual, bracket-like or lumpy and variable in shape, consisting of a single or several (up to 15) partly confluent caps, which are compact, initially white to cream, but develop a reddish tint as they age or dry, soft and spongiose when fresh, hard when dry. Taste and smell mild. Pileus 5-10 cm wide, broad at the base, semicircular, upper surface rough, covered with sterile, stiff, scattered hairs. Margin often inrolled. Spines up to 15 mm long, cylindrical, acute, creamy white when fresh, turning reddish when dry.
Section: Context up to 5 mm thick, homogeneous, tough, ochraceous-white. Trama of the spines homogeneous, though, pale ochraceous. No zonation between context and trama.
Hyphal system monomitic. Generative hyphae 2-13 µm in diam, infrequently septate with clamp connections, branched, thick- or thin-walled, inflated, IKI-. Gloeoplerous hyphae in the trama 3-8 µm in diam, filled with oily matter, protruding to the hymenium as gloeocystidia. Basidia slender, 25 x 4 µm, four-spored, with basal clamp. Spores ellipsoid or subglobose, hyaline, smooth, 3.5-4.5 x 2.6-3.5 µm, IKI blue, CB-.
