It may be noted that the type specimen of Polyporits 

 eurocephaliLS in Herb. Peradeniya is parasitized by a Hypo- 

 myces, and its tubes are filled with globose spores, 5-7 m in 

 diameter, covered with close-set spines 15 fi long. 



49. — Polystictus sanguineus (Linn.) Mey. 



The spores of tliis well known species are white , oval, 3 X 2 M. 

 There is a white variety of it , which grows with the red specimens.

Adnate, determinate, waxy when fresh, coriaceous and 

 rather brittle when dry, thin ; at first wliite, then pale 

 ochraceous ; substance white, about 0*25 mm. thick ; margin 

 sometimes recurved and then displaying a tomentose, obscu^ply 

 zoned, white lower surface ; circular, up to 2 cms. diameter, or 

 irregular and confluent up to 11 cm. long, and 5 cm. broad ; 

 hymenium plane at first, then covered with scattered, erect, 

 laterally compressed, triangular teeth, more or less radially 

 and concentrically arranged, which subsequently coalesce into 

 radiating or concentric, anastomosing ridges, usually toothed, 

 laterally compressed, up to 1 mm. high. The ridges are 

 distant and form a network with meshes up to 2 cms. broad, 

 with numeroas isolated teeth between. The whole hymenium, 

 i.e., the ridges and the plane surfaces between them, bristles 

 with minute cystidia ; these are up to 120 /< long and 20 m 

 diameter at the base, projecting 50 to 80 m above the sm'face, 

 conical, tapering gradually to the usually blunt apex, hyaline, 

 rough, with a central hollow. Basidia clavate, 70 ^ high, 

 12/1 diameter at the apex, 6 fi diameter at the base. Spores 

 from fresh specimens are white in mass, greenish-hyaline when 

 magnified, oblong-oval, 8-12 X 4-5 m, contents granular, 

 not guttulate.
