clavate, at length subrectangiilar, multiseptate, constricted,

Its first appearance is that of orbicular white downy patches, eonsistinar 

 of suberect slightly branched threads. These soon vanish, leaving a dark- 

 olive green stratum, consisting at first of short clavate filaments, mth on«? 

 or two septa. Their apices gradually become much incrassated, and the 

 number of articulations increases. The septa are mostly horizontal, with a 

 few vertical ones ; a few occasionally are inclined. In this state the colour 

 is yellowish when viewed by transmitted light. _ The spores gradually as- 

 sume a browner tint, become more and more distinct from the peduncle, and 

 at length fall off. acquiring a rectangular outline, resembling very much little 

 corded bales, from which circumstance the name is taken. They vary 

 greatly in size, and in the number of cells. A few of the peduncles are seen 

 amongst the spores, their articulations being frequently swollen above. —

Spots pulverulent, velvety, black ; flocci flexuous, articulated,

On decorticated osier twigs of an old hamper. Sept. Ape- 

 thorpe. 



Spots elongated, black ; flocci minute, waved, brown below, pellucid 

 above, often with the rudiment of a branch at the apex_; spores obovate, 

 with about three principal dissepiments, which are divided vertically or 

 obliquely, furnished ^vith a very short pellucid peduncle. This peduncle at 

 length vanishes, and they lose their obovate form and become oblong. —

Flocci obsolete, sporidia clavate, antenn^eform, 5-11 septate, 

 rather longer than the peduncle. — Eng. Fl.Y.p. 339. 



On decaying cabbage leaves. King's Cliffe. 



Intermixed with Claclos^oHum herbarwrn,, of which it is probably a condi-

Macrosporlum." 



Flocci erect, septate, of two forms, distinctly united in small 

 fascicles ; spores large, pedicellate, oblong-clavate, tawny, with 

 the endochrome divided transversely, and here and there longi- 

 tudinally, into numerous cells; pedicels hyaline. — Ann. des So.
