Description:Coltricia perennis (Fr.) Murr. Figures 5, 10, 16 Ryvarden (1976) 127; Gilbertson and Ryvarden (1986) 209; Yokoyama (1989) 467. Polystictus perennis L. ex Fr.; Thind and Chatrath, Res. Bull. Panjab Univ. n. 129 (157) 473.
1 give the following notes on this common temperate species for comparison with its tropical allies. The appearance of the hyphae is figured by Gilbertson and Ryvarden. It is interesting to note that the construction of the villous superficial layer on the pileus and stem is that of the dissepiments without their strict geotropic allignment. Thind and Chatrath describe the species as common on bare soil in the Mussoorie Hills but, as they give the spores as brown in the mass 5-7 x 4-5 µm, and do not mention the narrow interweaving hyphae, it seems that their fungus may have been C. cinnamomea.
Pores 100-150 µm wide on delimitation, becoming 150-350(-400) wide through attenuation of the dissepiments 70-130 µm wide. Spores 6-11 x 4-6.5 µm, ellipsoid with smooth, slightly thickened and pale yellow brownish walls, 1 large gutta 34.5 µm wide, slightly dextrinoid. Basidia 15-23 x 7-10 µm ; sterigmata (2-)4, 33.5um long. Cystidia and setae none. Hyphae monomitic coltricioid with nests of narrow coralloid hyphae, without clamps; main hyphae 5-9 µm wide, -10 µm in places, 3-5 µm in the dissepiments, with yellowish brown walls slightly thickened -0.5 µm, frequently branched commonly with Y-branching, longitudinal, septate at intervals of 50-460 µm, not secondarily septate; narrow hyphae 1.5-4 µm wide, septate with thin or sligthly thickened walls, much branched, often much lobulate with abortive processes, often of limited growth, sometimes elongate between the skeletals but usually densely interwoven as clusters or skeins in the stem and centre of the pileus but never sufficient to felt the tissue, derived from the narrower main hyphae; dissepiments similarly coltricioid but without dense skeins of narrow hyphae. Hymenium developed from the narrow hyphae by rather distant subterminal branching from hyphae descending the surface of the dissepiment (as in Aurificaria indica). Surface of stem subvillous with the free ends, 3-6(-8) µm wide, of hyphae diverted obliquely upwards, 0.5-1 mm long, but more spreading near the base of the stem, with pale yellow brown walls 0.5-1.5 µm thick, shortening 100-150 µm long at the stem-apex, distantly septate, mostly unbranched, straight or flexuous, the base of the villous layer becoming invaded by narrow hyphae from the base of the stem upwards. Surface of pileus subvillous as the stem, with a pile of main hyphal ends 350-500 µm long in the centre of the pileus and shortening to 100 µm near the margin, continually excrescent, on origin near the margin of the pileus 5-8 µm wide and much branched with obtuse ends, the walls thickening -2 µm and yellow brown, septate, the branching typically at a wide angle and pseudodichotomous, the branches spreading and even recurved or crozier-like, thus matting the villous pile but not invaded by narrow hyphae, in older parts of the surface the hyphal ends mostly unbranched, tapering and colourless giving the greyish appearance of old pilei, occasionally with slight agglutination at the base of the villous layer in a tenuous crust 30-50 µm thick. Dissepiments composed of descending, sparingly branched, septate hyphae 3-5 µm wide with yellow brown walls 0.51 m thick, with the narrow hyphae 1.5-3 µm wide, not forming tangled skeins, the main hyphae derived in the pore-field as laterals of the main hyphae of the flesh and not from the narrow hyphae; eventually the descending main hyphae with less branching and causing the attenuation of the dissepiments to widen the pores.
