308 FUXGUS-FLOBA. 



2x3 mm. broad ; externally and the margin clothed with 

 thin-walled, septate, obtuse, straight or slightly wavy, 

 reddish-brown hairs, 100-200 X 5-7 fx; disc dingy olive, 

 externally purple-brown, hypothecium and excipulum paren- 

 chymatous, cortical cells irregularly hexagonal, 8-12 \x 

 across; asci clavate, apex slightly narrowed, 8-spored ; 

 spores irregularly 2-seriate, smooth, hyaline, elliptical, ends 

 rather pointed, for a long time continuous and 2-guttulate, 

 then becoming 3-septate 10-12 x 3 /x ; paraphyses slender, 

 hyaline, as long as the asci, bearing at the tip a hyaline, 

 fusiform, smooth, 3-5-septate conidium 30-50 X 5—6 /x.

On the ground, 



When the conidia are mature they fall away; many were 

 found germinating in the specimen examined. Some of the 

 spores had a brownish tinge, but whether this is normal or 

 due to age or poisoning for preservation, cannot be determined 

 until fresh specimens are examined. 



Type specimen, in Herb. Kew, examined. 



LACHNEA, Fries, (figs. 5-9, and 20, 21, p. 290.) 



Ascophore sessile, margin at first incurved and depresso- 

 globose, finally becoming quite plane, rather fleshy ; disc- 

 bright coloured, whitish, or grey ; externally hairy, hairs best 

 developed at the margin, where they are straight, thick- 

 walled, septate, pointed, coloured, and spreading like a 

 fringe when the plant is expanded ; cortex parenchymatous ; 

 asci cylindrical, 8-spored ; spores obliquely 1 -seriate, hyaline 

 continuous, elliptical, smooth or ornamented with warts or

Growing on the ground, rarely on wood. Distinguished 

 among genera having rigid, pointed, septate marginal hairs, 

 by the continuous spores and clavate paraphyses.
