SPOROTRICHINM 



1117 



Trichothecium roseum Persoon, 1801. 



Synonyms.^ — -Tnchoderma roseum Persoon, 1801; Sporocephalum 

 roseum Persoon, 1801 ;Puccinia rosea Corda, 1837. 



This species vegetates on decaying vegetable matter; the colour 

 is at first white, then pinkish. Each fertile hypha terminates in a 

 pear-shaped conidium, 10 to 20 /j, in length and 8 to 12 in breadth. 



This fungus has been found in cases of otomycosis by Stendener, 

 who did not succeed in cultivating it. Some authorities believe 

 it to be identical to Glenospora graphii. 



SUBORDER 2. SPOROTRICHINEiE VuiLLEMiN, 1910. 



Definition. — -Conidiosporales in which reproduction takes place 

 by means of true conidia, but in which true conidiophores are absent. 



Type Genus. — Sporotrichum Link, 1809, which has a very large 

 number of species scattered over the world, of which 100 are de- 

 scribed in Saccardo's ' Sylloge Fungorum,' vol. iv. 



Genus Sporotrichum Link, 1809, emendavit Saccardo, 1882. 



Synonyms.' — Miainomyces Corda; Chromelsporium Corda. 



Definition. — -Sporotrichales with the characters of the suborder. 



Type Species.— Possibly Sporotrichum obducens Link, 1809. 



Human Species. — There has been considerable discussion as to 

 whether the human species belonged to this or another genus — ■ 

 e.g., Odspora, Botrytis, Trichosporum, Rhinocladium, or Torula — 

 but Smith, de Beurmann, and Gougerot's belief that Sporotrichum 

 is the correct genus has been supported by Matruchot, Vuillemin, 

 and Pinoy, and may be considered as settled as far as our present 

 knowledge goes. 



The first species ever associated in any way with man was :• — 



Sporotrichum inquinatum (Link, 1809), which was found growing 

 on dry human faeces. This was probably a saprophyte. The first 

 ever found in diseased men was Sporotrichum bronchiale Montague, 

 1844. It was discovered by Gubler in the bronchi of sick persons. 



Species Parasitic in Man. — -It is customary at the present time to 

 give the following species as parasitic in man, and it may be noted 

 that they do not correspond to any known species living sapro- 

 phytically or parasitically on plants :—
