** Distinctly stij/ntate. 



Helotium luteolum. Currey, Linn. Trans, xxiv., 

 p. 153, t. 25, figs. 11, 12, and 18. 



Caespitose, stipitate, concave, soon plane or slightly- 

 convex, rather fleshy, margin and stem very minutely 

 downy, 1-2 mm. diameter; hypothecium and excipulum 

 formed of hyaline, stout, septate, interwoven hyphae passing 

 into a pseudoparenchymatous cortex, and running out at 

 the margin into slender, short, parallel hyphae, the tips of 

 which are often rough with particles of oxalate of lime; 

 stem 3-5 mm. long, slender, equal, sometimes branched; 

 every part of fungus pale primrose-yellow, or sometimes 

 straw-colour ; asci narrowly cylindric-clavate, apex narrowed, 

 pedicel slender, often crooked, 8-spored; spoi'es irregularly 

 2-seriate, hyaline, continuous, smooth, straight or slightly 

 curved, 10-12 x 2 '5-3 /a, narrowly cylindric-fusiform ; para- 

 physes broadly lanceolate, apex more or less acute, 2-3- 

 septate, hyaline 5-6 /«, wide at the broadest part. 



Lachnella luteola, Phil., Brit. Disc, p. 247. 



Dasyscyplia luteola, Sacc, Syll. viii., no. 1830. 



On dead wood and branches in damp places, among 

 moss, &c. 



Distinguished by the caespitose habit, uniform pale yellow 

 colour, and more especially by the remarkable paraphyses. 

 Very beautiful specimens of this species were found growing 

 on branches buried among moss near Worcester, by Mr. 

 Carleton Eea, in September 1894. The species is obviously 

 a good Helotium, as originally proposed by Currey, in spite 

 of the one deviation presented by the peculiar paraphyses. 

 The minute marginal down is not to be compared with the 

 pilose exterior of species of Basyscypha. 



Type specimen examined.

Gregarious, stipitate, closed at first, then expanding until 

 almost or quite plane, discoid, rather fleshy, glabrous, dark 

 yellow, 1-2 mm. across; stem li-2'J mm. high, slender, 

 almost equal, pale, basal portion coated with delicate down,
