ECCHYNA. TREMELLA 729 



ECCHYNINEAE. 



Hymenium inclosed within a peridium. 



ECCHYNACEAE. 



Same characters as suborder. 



Ecchyna Fr. 



(eK'xyvw, I pour out.) 



Peridium fibrillose, subglobose, stipitate, or substipitate, thin, fuga- 

 cious. Gleba threads radiating, branched, flexuose at the ends. Basidia 

 cylindrical, straight, or curved, transversely 3-septate ; bearing sessile, 

 or very short pedicellate spores; scattered, or in tufts on the lower 

 portions of the threads. Spores fawn colour, elliptical, or subglobose, 

 smooth, producing sporidiola on germination. Growing on wood. 



2485. E. faginea (B. & Br.) Fr. (= Pilacre faginea B. & Br.; Pilacre 

 Petersii Berk. & Curt. 1 ) B. & Br. Ann. Nat. Hist. no. 380, 1. 11, 

 fig. 5, as Pilacre faginea. Faginea, pertaining to beech. 



P. 3-6 mm. high, 1-3 mm. across, whitish, or fawn colour, forming 

 a globose head, smooth, then pulverulent. St. concolorous, or be- 

 coming block with age. Flesh fawn colour, floccose, loose. Spores fawn 

 colour, elliptical, or subglobose, depressed or umbilicate on the one 

 side, 5-6 x 4-5 /u,; basidia cylindrical, 3-septate. Hyphae concolorous, 

 3-4 /A in diam., with numerous clamp connections. Beech, ash, horn- 

 beam, and holly. Sept. Jan. Not uncommon. 



TREMELLALES. 



Basidia subglobose, longitudinally, or vertically, cruciately divided 

 into 24 parts. Spores producing sporidiola or a mycelium on germina- 

 tion. 



TBEMELLACEAE. 



Same characters as the order. 



Tremella (Dill.) Fr. 

 (Tremo, I tremble.) 



Receptacle gelatinous, or waxy, soft; foliaceous, brain-like, or 

 tubercular. Hymenium spread over the whole surface, very rarely 

 papillate. Basidia amphigenous, superficial, or immersed. Conidia 

 on the same receptacle, preceding, or accompanying the spores. 

 Spores white, rarely yellowish, globose, subglobose, oval, elliptical, 



1 Bayliss- Elliott and Grove hazard the opinion that both these species are 

 only conidial forms of Boeder ia pallida Sacc., but the transversely septate 

 basidia, and frequent clamp connections of the hyphae seem to disprove this 

 conclusion.
