24 FUNGUS-FLORA, 



A. Spores coloured. 

 FAELOWIA. Sacc. (figs. 5-9, p. 22.) 



Ascophore elongated, dehiscing by a long, narrow slit, lips 

 obtuse, black, rigid ; asci elongated ; spores continuous, 

 coloured ; paraphyses present. 



Farlowia, Sacc., Syll., vol. ii. p. 727. 



Eeadily distinguished from every other genus by the con- 

 tinuous, coloured spores. 



Farlowia repanda. Sacc., Syll., n. 5566. (figs. 5-9, 

 p. 22.) 



Ascophore rather broadly elliptical, straight or rarely 

 slightly curved, ends rather obtuse, up to 1 mm. long, de- 

 hiscing by a narrow slit, lips convex, obtuse, smooth, dull 

 black; asci cylindric-clavate, spores 8, obliquely uniseriate 

 or sometimes more or less biseriate towards the apex of the 

 ascus, elliptical, slightly inequilateral, smooth, pale, then 

 deep brown, with a more or less developed hyaline basal 

 papilla, usually 1-guttulate, 15-17 x 6-8 /z; paraphyses 

 numerous, filiform, 2 fj. thick, sparingly septate, very slightly 

 thickened, and sometimes branched above, tinged with 

 olive. 



Hysterium rcpandum, Bloxam in Duby, Hyst., p. 27, t. 1, 

 f. 6 ; B. & Br., Ann. Nat. Hist., ser. iii., vol. xviii., p. 15, pi. 5, 

 f. 38 (n. 1181); Cke., Hdbk., p. 758. 



On rotten wood, stumps, &c. 



Gregarious, lying at all angles. Superficially indistin- 

 guishable from the many species belonging to other genera, 

 but readily known under the microscope by the continuous 

 brown spores with a minute, colourless, basal apiculus. 



Bloxam's type specimen examined. 



MYTILIDION. Duby. (figs. 39-41, p. 22.) 



Ascophore sessile, mussel-shaped, dehiscing by a narrow, 

 longitudinal slit ; vertical, laterally compressed, thin, car- 

 bonaceous and fragile, black ; ast-i subcylindrical or clavate,
