Robin added to the Trychophytse the fungus which Lebert 

 found in the scabs of an atonic ulcer of the leg. He describes 

 it thus : 



III. Species Trichophyton (?) ulcerum = Champignon des 

 ulceres. Tab. II, B, fig. 7. 



The scabs showed here and there dry yellow spots, of about 

 1 2 mm. in circumference, and looked like mould. The 

 fungus consisted of round or slightly elliptical spores, 0*005 

 O'OIO mm. large, with nuclei of 0*002 mm. In some a double 

 enveloping membrane could be recognised. There were also 

 other spores, from 0*010 0*015 mm. long, and full of small 

 globules. The former joined, arid formed threads like strings of 

 pearls, some of which were branched. Every transition from the 

 simple globules to the threads and branches could be made out. 

 I cannot see why this fungus is placed here, but am not inclined 

 to find it another place.

MICROSPOK^:. 



Genus Microsporon (Gruby). 



Filamenta undulata, directionem capillorum secuta ; transpa- 

 rentia, 0*002-3 mm. lata, sine granulationibus, interdum bifur- 

 cata sub angulo 30 40. Filamenta et rami internum stratum, 

 spori externum for mantes. Spori propinquissimi, plerumque rotundi, 

 interdum ovales ; omnes transparentes, sine granulationibus. 

 Filam,enta (= trichomata] totius ordinis sunt ramosa, sine articula- 

 tionibus et granulationibus, sporos tamen parantia.
