242 FUNGUS-FLOEA. 



.shaped or almost plane, glabrous ; disc bright yellow, ex- 

 ternally pallid, about 1 mm. across ; stem glabrous, J-f mm. 

 across, expanding upwards into the ascophore, consisting 

 of parallel, septate hyphae, which continue outwards and 

 form the cortex of the ascophore ; asci elongated, narrowly 

 clavate, pedicel long, slender, 8-spored ; spores obliquely 

 1 -seriate, or inclined to be 2-seriate up wards, hyaline, smooth, 

 continuous, rather broadly elliptical, ends somewhat pointed, 

 10-12 x 5—6 /x; paraphyses slender, hyaline, cylindrical 

 septate, sometimes branched, about 1*5 /x thick throughout. 



Peziza flava, Klotzsch, MS., in Herb., Kew. 



On decorticated wood. 



Type specimen examined. 



The measurement of the spores — 20 X 4-5 /x — is an un- 

 corrected slip for 10-12 X 4-5 /x, the measurements given by 

 Phillips, along with a figure made when the specimen was 

 examined by him.

 n. 1487, ser. iv., vol. xv., p. 38 (1875); Phil., Brit. Disc, 

 p. 160. 



Scattered, shortly stipitate, at first closed, then becoming 

 almost or quite plane, margin often wavy, pale honey colour, 

 glabrous, 1-lJ mm. across; hypothecium and excijraluni 

 parenchymatous, cortical cells polygonal or subquadrate, 

 almost uniform in size throughout, 7-10 fx diameter; asci 

 narrowly clavate, apex narrowed, pedicel long, slender, 

 8-spored ; spores irregularly 2-seriate, smooth, hyaline, 

 narrowly fusiform, ends rather acute, often very slightly 

 bent or with a suggestion of becoming sigmoid, often multi- 

 •guttulate, 28-32 X 5-6 /x ; paraphyses hyaline, about 1 \ ft 

 thick, scarcely or often not at all thickened at the tips. 



Helotium Fergussoni, Sacc, Svll., viii. n. 948. 



Oh rotten wood. 



Type specimen examined. 



A very fine and distinct species, well marked by the size 

 and shape of the spores. The present species was published 

 in January, 1875, and later in the same year Berkeley and 

 Broome published a second, quite distinct species from 

 Ceylon as Helotium melleum, B. & Br., — Fung. Ceylon, n. 597; 

 Linn. Soc. Journ., vol. xiv. p. 107.
