738 SEBACINA. EICHLERIELLA

2519. S. (Heteroch.) crystallina Bourd. in Trans. Brit. Myc. Soc. vn, 

 text fig. 2, p. 52. Kpvcrrd\\ivo<;, crystalline. 



R. *5 2 cm., hyaline, indeterminate, interruptedly effused, ceraceo- 

 gelatinous, transparent, then collapsed and depressed, very thin, 

 rough with hyaline setae under a lens', margin similar, or less con- 

 tinuous and reticulate. Spores hyaline, subglobose, or obovate, more 

 or less apiculate at the base, (4)-4-5-6 x (3)-4-5ju, often 1-guttulate, 

 germinating laterally or at the apiculus and then truly elongate, or 

 conical; basidia obovate, or subglobose, 8-12 x 6-9 /A, longitudinally 

 septate, with 2-4 subulate sterigmata, 5-6/A and finally up to 15/u, 

 long. Cystidia scattered, or fasciculate, cylindrical, obtuse, 60-180 x 

 7 12/x, projecting 10-45/u, above the hymenium, thin walled. Very 

 rotten pine and jumper wood. Not uncommon, (v.v.) 



Subgenus Bourdotia Bres. 



(L'abbe H. Bourdot, the eminent French mycologist.) 

 Receptacle waxy or pulverulent, entirely resupinate, with the habit 

 of a Corticium, possessing tubular, thin walled gloeocystidia, filled 

 with a coloured juice, and rising perpendicularly in the hyphae.

 Wakef. sec. Bres.) 



Rev. W. L. W. Eyre, a former President of the British Myco- 



logical Society. 



R. 2-6 cm., hyaline grey, becoming whitish grey when dry, broadly 

 and irregularly effused, closely adnate. Hymenium concolorous, 

 smooth, or here and there tuberculate. Flesh very thin, 40-45 p 

 thick. Spores white, globose, 4-6 p.; basidia at first obovate, con- 

 tinuous, at length longitudinally, cruciately divided into 4 parts, 

 10-13 x 7-8 /it, with 4 curved sterigmata, 7-9 x 1-5/z (at the base). 

 Gloeocystidia very numerous, arising from the base, not or scarcely 

 projecting, cylindrical, or subfusiform, 25-35 x 5-7 /A, filled with a 

 granular, yellow olivaceous juice. Vegetative hyphae either thin and 

 hyaline, or red brown, thicker walled, 3-6ju, in diam., frequently 

 septate, sometimes almost moniliform. The coloured hyphae often 

 stain the wood a bright orange-red. Decorticated beech log. May 

 Oct. Rare. 



Eichleriella Bres. 

 (Bogumil Eichler.) 



Receptacle coriaceous, waxy, or membranaceous, subgelatinous, 

 cup-shaped, or plano-concave, rarely pendulous; margin free. Hy- 

 menium smooth, rugulose, or Radulum-like. Basidia globose-ovoid,
