MUCEDINES. 



Synopsis of British and nearly allied Conti- 

 nental Genera. 



A. Fertile filaments (pedicels) simple or 

 branched, terminating in single spores or 

 a very short row. 



t Spores simple. 



I. BOTRYTIS. Pedicels erect, septate, 

 branched ; branches and branchlets septate ; 

 spores solitary, on the tips of the branchlets. 



II. VERTICILLIUM. Pedicels erect, sep- 

 tate, with whorled branches terminating in 

 a solitary spore, or a short row of spores. 



III. ACREMONIUM. Pedicels creeping, 

 septate, armed with subulate branches bear- 

 ing spores. 



IV. OIDIUM. Pedicels simple, short, 

 erect, clavate, septate, bearing usually one, 

 sometimes two more or less oval spores. 



V. FUSIDIUM. Pedicels? Spores elon- 

 gate, fusiform. 



VI. MENISPORA. Pedicels erect, septate, 

 bearing fusiform or cylindrical spores, at first 

 joined in bundles. 



VII. SCEPTROMYCES. Pedicels erect, 

 geniculate, verticillately branched ; branches 

 short, racemose; sporesin grape-like bunches. 



** Spores septate. 



VIII. BRACHYCLADIUM. Pedicels 

 branched above, septate, moniliform; branches 

 and branchlets forming a sporiferous capitu- 

 lum ; spores transversely septate. 



IX. PAPULASPORA. Pedicels erect, 

 short, articulate, simple or slightly branched, 

 each terminating in an oblong two- or four- 

 partite spore. 



X. TRICHOTHECIUM. Pedicels inter- 

 woven in tufts, the central erect, fertile; 

 spores acrogenous, didymous, free, com- 

 monly loosely heaped together. 



XI. CEPHALOTHECIUM. Pedicels sim- 

 ple, continuous, bearing a terminal head of 

 didymous spores. 



B. Erect filaments (pedicels) terminating 

 in strings of spores. 



* Spores simple. 



XII. PENICILLIUM. Pedicels erect, sep- 

 tate, penicillately branched above ; branches 

 and branchlets septate; strings of spores 

 attached to the tips of the branches. 



XIII. ASPERGILLUS. Pedicels conti- 

 nuous, erect, simple filaments, inflated into 

 a little head at the summit ; strings of spores 

 crowded upon the head. 



XIV. SPOROTRICHUM. Pedicels erect, 

 simple, or slightly branched, septate and 

 articulate, articulations remote, inflated ; 

 spores simple, usually found collected in 

 heaps among the filaments. 



XV. RHODOCEPHALUS. Pedicels erect, 

 continuous, not septate, divided at the sum- 

 mit into simple branchlets forming a capitu- 

 lum; strings of spores attached singly to 

 the tips of the branchlets. 



XVI. GONATORHODUM. Pedicels erect, 

 septate, nodulose, with minute sporomor- 

 phous branchlets crowded in whorls, septate, 

 affixed to the nodules, bearing chains of 

 spores at the apex. 



XVII. MONILIA. Pedicels erect, sep- 

 tate, crowded at the summit with chain- 

 like branches composed of strings of spores 

 soon falling apart. 



** Spores septate. 



XVIII. DACTYLIUM. Pedicels erect, 

 septate, unbranched; strings of spores at- 

 tached in a bunch to the apex ; spores sep- 

 tate. 



XIX. DENDRYPHIUM. Pedicels erect, 

 septate, branched above ; strings of septate 

 spores attached singly or in pairs to the 

 apices of the branches. 



C. Fertile filaments (pedicels), inflated at the 

 tips or at various points in their length, 

 with projecting points or warts on the 

 inflations bearing 



* Simple spores. 



XX. RHINOTRICHUM. Pedicels erect, 

 septate, sometimes sparingly branched, the 

 apices clavate, bearing scattered points sup- 

 porting simple spores. 



XXI. STACHYLIDIUM. Pedicels erect, 

 articulated, whorled-branched above ; branch- 

 lets geniculate and articulate; spores sub- 

 pedicellate, accumulated in little capituli- 

 form heads inserted at the tips of the 

 branches. 



XXII. GONATOBOTRYS. Pedicels erect, 

 septate, nodulose; nodules distant, warty; 

 warts spirally arranged, and bearing con- 

 globated solitary spores. 



XXIII. ACMOSPORIUM. Pedicels erect, 

 septate, branched above; branches and 

 branchlets forming a cyme, thickened at the 

 apex, and furnished with globular capitules 

 covered all over with points ; spores simple, 

 attached on the points of the capitules. 



XXIV. HAPLOTRICHUM. Pedicels erect, 

 septate, terminating above in a continuous,
