DACTYLELLA. 343 



solitary, terminal, perfectly hyaline, clavulate, 6-8-septate 

 (jonidium, measuring CO-70 x 14r-15 /n. 



Dactylella minuta, Grove, Journ. Bot. 1884, p. 199, t. 246, 

 f. 6 ; Sacc, Syll., iv. n. 937. 



On dead wood. 



This species closely resembles Dactylium candidum, Nees 

 (Bonord. Hdbk., p. 82, f. 189), but differs in the form of the 

 spores, if Bonordtn's figure be correct, and in their constant 

 position as a continuation of the stem. It is certainly not 

 congeneric with Dactylaria purpurella, Sacc. (Fung. Ital., 

 £ 8). (Grove.) 



Var. fusiformis. Distinguished from type by the gre- 

 garious or caespitose hyphae, and the elongato-fusoid 

 conidia, 60-75 x 7-9. 



Dactylella rhombospora. Grove. 



Very much scattered and exceedingly delicate, closely 

 resembling Dactylella minuta, but differing in the form of 

 the conidia, which are broadly fusoid, almost rhomboid, and 

 obtuse at both ends. 



Dactylella rJiombospora, Grove, Journ. Bot., t. 257, f. 4 ; 

 Sacc, Syll., iv. n. 938.

Dactylella ellipsospora. Grove. 



Pure white, in effused lufts ; fertile hyphae slender, erect, 

 not or very sparingly septate, white, 100-200 x 4 /i ; 

 conidia elliptical, rather acute at both ends, colourless, 

 guttulate, then a slender septum is formed near to each end, 

 central cell with one large vacuole, 40-50 x 16-18 /a. 



Dactylella ellipsospora. Grove, Sacc, Syll., iv. n. 939. 



Menispora ellipsospora, Preuss, F. Hoyersw., n. 69. 



On rotten wood, &c. 



Dactylella implexa. Sacc. (fig. 25, p. 274.) 



Forming an exceedingly thin greyish- white film; fertile 

 hyphae simple or very sparingly branched above, erect, 

 septate; conidia subojliudrical, base apiculate, 3-septate,
