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 cinnabarlna B. & C. Spores 

 oblong, curved, hyaline, 16-18x4-6 mk. A'. Name salix, willow. Fr. 

 Hym. Eur. p. 647. B. &> Br. n. 1581. 5. 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 eveii^ 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. er 1 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 

 a., fj.op(f>r), form. Without regular form. Fr. Hym. Eur. p. 648. B. & Br. 

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



II. HIMANTI^E. 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 

 giganteus. Of very large size. Fr. Hym. Eur. p. 648. Berk. Out. p. 272. 

 C. Hbk. 11. 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. /. 273. 

 C. Hbk. n. 923. S. Mycol. Scot. n. 876. Bonord. f. 259.
