Sarcosoma orientale Pat. (Bull. Soc. Myc. France, Vol. 

 XXV., p. 3) from Annam, is closely allied to, if not identical 

 with, the present species. It has the same habit. It differs 

 in having its disc orange-yellow, and its spores 42-50 X 

 16-18 f^. In other points it agrees with S. Thwaitesii.

Peziza rhytidia Berk, in Massee, Journ. Linn. Soc, XXXI., 

 p. 502. 



This species has been re-examined by Massee {loc. cit.) who 

 considers that it is identical with Peziza rhytidia Berk. His 

 description of Peziza rhytidia does not quite fit the Ceylon 

 species, but it is difficult to decide in what degree this is due 

 to the fact that it was drawn up from dried specimens. Peziza 

 reticulata appears to differ from P. rhytidia in being sub- 

 gelatinous, in the colour of the disc, in its stouter paraphyses, 

 and in its larger spores. 



Gregarious ; ascophore up to 7 cms. diameter, 1 cm. thick, 

 almost sessile, or prolonged into a conical stalk up to 8 cms. 

 high ; entirely subgelatinous ; disc cup shaped, becoming 

 plane or undulating, circular ; margin even, remaining 

 incurved for some time ; externally black, lacunose, slightly 

 Velvety, strigose or naked at the base ; internally blackish, 

 strongly gelatinous ; disc at first black, then chocolate. It 

 contracts when dry into a thin horny plate, and is then reti- 

 culated underneath, but there are no "raised anastomosing 

 ribs " on the fresh specimens. Asci 400-440 X 15-18 i", 

 uniformly cylindrical with a slightly curved pedicel, apex 

 rounded and not blue with iodine, eight-spored, spores 

 uniseriate or obliquely uniseriate. Spores hyahne, smooth, 

 oblong-oval, curved, ends obtuse, 25-34 x 13-18 yu, two or 

 three guttulate. Paraphyses stout, up to 4 y" diameter, 

 septate, sUghtly inflated at the tips, branched. On dead 

 wood, sometimes on Rhododendron leaves ; Hakgala. 



P. rhytidia is said to have very slender paraphyses, spores 

 25 X 10-11 fi, a black disc, and raised anastomosing ribs on 

 the exterior ; it is not said to be subgelatinous.
