304 FUNGUS-FLORA. 



Tribe o. Botrytideae. Sacc. 

 HAPLAEIA. Link. (fig. 16, p. 313.) 



Mycelium creeping ; fertile branches erect, septate, once 

 or several times bifurcating ; conidia globose or elliptical, 

 one-celled, almost colourless, sessile and springing laterally 

 from the branches. 



Haplaria, Link., Obs., i. p. 9 ; Sacc, Sjll., iv. p. 85. 



I am not acquainted with the species constituting the 

 present genus, and am not certain as to the origin of the 

 conidia which in figures are represented as scattered in an 

 irregular manner over the branches. 



Haplaria grisea. Link. (fig. 16, p. 313.) 

 Forming minute greyish tufts ; hyphae very slender, 

 rather rigid, simple or forked, becoming thin at the tip, 

 sparingly septate ; conidia subglobose, very minute, at first 

 clustered near to or below the tip, then becoming dispersed 

 over every part, subhyaline. 



Haplaria grisea, Link, Obs., i. p. 9, f. 12 ; Sacc, Syll., iv. 

 n. 414. 



On damp grass leaves. 



HYPHODEEMA. Fries, (fig. 33, p. 313.) 



Mycelium very thin, septate, creeping and forming an 

 effused stratum that is covered with erect, very slender, 

 closely packed branches, each bearing a one-celled conidiuni 

 at the apex. 



Hyplioderma, Fries, Sum. Yeg. Scand., p. 447 ; Sacc, Syll., 

 iv. p. 89. 



Forming crust-like patches resembling a Corticium. 



Hyphoderma roseum. Fr. (fig. 33, p. 313.) 

 Tufts compressed, at first rounded then effused, minutely 

 villose, margin minutely radiato-byssoid ; fertile braucbes 

 very slender, erect, parallel, crowded, with a globose, rose- 

 coloured conidium at the apex, 7-8 fx diameter.
