fl Growing on wood and branches. 



Lachnea erinacea. Sacc, Syll., viii. n. 741. 



Gregarious, sessile, closed at first but soon becoming plane, 

 rather fleshy, 3-6 mm. across ; disc whitish, externally 

 pilose, hairs bright brown, the marginal ones very long 

 and stout, thick- walled, tapering to an acute point, septate, 

 300-500 X 14-18 jx ; often branched at the base; cortex 

 parenchymatous, cells large ; asci cylindrical, apex slightly 

 truncate, 8-spored ; spores obliquely 1 -seriate, broadly 

 elliptical, ends obtuse, hyaline, smooth, usually 1-guttulate, 

 contents often coarsely granular, 17-20 X 10 /x; paraphyses 

 rather slender, septate, clavate. 



Peziza erinacea, Schweinitz, Cooke, Mycogr., fig. 140. 



On rotten wood. 



Distinguished among the white species by the densely 

 crowded, very long, stout marginal hairs. 



Specimen from Schweinitz, now in Kew Herbarium, 

 examined. 



Lachnea livida. Phil., Brit. Disc, p. 221 (spores 

 incorrectly described as " asperate"); Sacc, Syll., viii. n. 759. 



Gregarious, sessile, base narrowed, at first closed and 

 subglobose, then becoming nearly plane, up to h cm. 

 across ; disc grey or dull lead-colour, externally, and the 

 margin everywhere densely covered with stout, very thick- 

 walled, septate brown hairs, slightly largest at the margin, 

 and then 200-250 x 20-25 yu, the tip in some cases is 

 gradually narrowed to a point, in others quite obtuse ; 

 excipulum composed of radially parallel, septate hyaline 

 hyphae, these become wider and pseudoparenchymatous at the 

 cortex ; asci cylindrical, 8-spored ; spores obliquely uniseriate, 

 hyaline, smooth, contents often granular, broadly elliptical, 

 ends obtuse, 18-20 X 10-11 ; paraphyses septate, clavate.
