274 THELEPHOREI. 



Corticium. Hymenium rather even, naked, persistently red- blood- colour, 

 continuous when dry. 



Very elegant, entirely like a Peziza. It varies becoming smooth. 



On Salix aurata. Kinrara, Morayshire. Aug.-Sept. 



Berkeley considers this the same with Exidia cinnabarina B. & C. Spores 

 oblong, curved, hyaline, 16-18 x 4-6 mk. K. Name salix, willow. Fr. 

 Hym. Eur. p. 647. B. & Br. n. 1581. S. Mycol. Scot. n. 873. 



3. C. amorphum Fr. 4-6 mm. (2-3 lin.) broad, white-tomentose 

 externally, waxy-pliant, somewhat coriaceous, cup-shaped then 



flattened, confluent, marginate. Hymenium even, continuous, 

 pale. 



On silver-fir. Perth. Dunkeld. Keir. Aug.-Oct. 



The substance is white and fleshy, consisting of rather coarse threads, which 

 at the base form a close sclerotioid network. The hymenium consists of 

 colourless threads, and orange-coloured clavate bodies filled with pigment. 



B. & Br. There is considerable doubt whether this is a true Corticium. 

 Fries says the habit is exactly that of Corticium of this section, but the struc- 

 ture of the disc is ambiguous. Berkeley, who compares it in appearance with 

 Peziza calycina, considers it may perhaps be the type of a new genus. Name 

 d, fJiopQij, form. Without regular form. Fr. Hym. Eur. p. 648. B. & Br. 

 n. 1582. S. Mycol. Scot. n. 874. Theleph. Fr. Elench. p. 183. 



II. HIMANTIJE. Resupinate, effused, immarginate, &c. 

 * Mycelium and circumference 'white. 



4. C. giganteum Fr. Hyaline -white, very broadly effused, 

 swelling when moist, waxy, when dry cartilaginous, of the con- 

 sistence of paper, free, milk-white, circumference strigoso-radiate. 

 Hymenium even, continuous. 



At the first agglutinated, but in contracting with dryness it breaks up, and 

 does not become cracked. Smaller and less perfect forms occur. 



On pine, stumps, &c. Common. Oct.-April. 



Spores ellipsoid or sphaeroid-ellipsoid, hyaline, 4-5 x 3 mk. K. Name 

 iganteus. Of very large size. Fr. Hyi~ "-- ' '" " * "- 1 ' - 



C. Hbk. n. 922. S. Mycol. Scot. n. 875. 



5. C. lacteum Fr. Milk-white, effused, membranaceous, laxly 

 fibrillose beneath and at the circumference. Hymenium (when 

 perfect) waxy, deeper in colour, divided by cracks when dry. 



Much smaller and thinner than C. giganteus. 

 On trunks, &c. Frequent. Nov.-Feb. 



Name lac, milk. Milk-white. Fr. Hym. Eur. p. 649. Berk. Out. p. 273.
