1. Botrytis. Pedicels erect, septate, branched ; branches 

 and branchlets septate ; spores solitary, on tips of branch- 

 lets, which are racemose, umbellate, cymose, etc. 



2. Peronosj)ora. Like 1, but pedicels without septa. 



3. Verticillium. Pedicels erect, septate, with whorled 

 branches terminating in a solitary spore or a short row of 

 spores. 



4. Acremomum. Pedicels short, subulate, branches from 

 a horizontal filament, bearing single smooth spores. 



5. Zygodesmus. Like 4, but with echinulate spores. 



6. Oidium. Pedicels simple, short, erect, clavate, sep- 

 tate, with one, sometimes two, oval spores. 



7. Fasidium. Spores elongate, fusiform. 



8. Menispora. Pedicels erect, septate, with fusiform 

 or cylindric spores, at first joined in bundles. 



9. Sceptromyces. Pedicels erect, geniculate, verticil- 

 lately branched ; branches short, racemose ; spores in 

 grapelike bunches. 



* * Spores septate. 



10. Brachydadium. Pedicels branched above, septate, 

 moniliform ; branches and branchlets forming a sporifer- 

 ous capitulum ; spores transversely septate. 



11. Trichothecium. Pedicels in tufts, the central erect, 

 fertile ; spores acrogeuous, didymous, free, commonly 

 loosely heaped. 



12. Cephalothecium. Pedicels simple, continuous, with 

 terminal head of didymous spores. 



B. Erect filaments (pedicels) terminating in strings of 

 spores. 



* Spores simple. 



13. Penicillium. Pedicels erect, septate, penicillately 

 branched above ; branches and branchlets septate ; strings 

 of spores at tips of branches. 



14. Sporotrichum. Pedicels simple or slightly branched, 

 septate and articulate, articulations remote, inflated ; 

 spores simple, usually in heaps among the filaments.
