BERKELEY S TYPES OF FUNGI. 523 
Lachnellula hysterigena, Sace. Syll. viii. n. 1613. 
-Exsicc. Rav. Fung. Carol. Exs. n. 46. 
Parasitic on the dise of Blitrydium nigro-cinnabarinum and 
on a species of Myriangium; also on the branches on which the 
host grows. 
Chislehurst, England (Currey); Italy (Cesati); Mt. Macedon, 
Victoria (Mrs. Martin, n. 460); Central Province, Ceylon 
(Thwaites, n. 1067) ; S. Carolina (Ravenel, nn. 551, 1778, 2346, 
3292). 
There is ample material of the three supposed species given as 
synonymous above, which do not differ in the slightest detail. 
The figure of a section of the ascophore given in my ‘ Fungus- 
Flora,' vol. iv. p. 222, is not quite correct, the hypothecium and 
excipulum being too distinctly parenchymatous. The species is 
well characterized by the small globose spores and by the slender 
hyaline spine-like hairs, curved at the tip and springing from 
the marginal cortical ‘cells. I consider the fungus as belonging 
to the genus Mollisiella rather than to Lachnellula, and in future 
it will be known as Mollisiella ilicincola.
