MEDICAL MYCOLOGY 



In his original description and figure, Corda shows a long eoremium with 

 tufts of spores on short branches. Saccardo and others have considered that 

 he had a CorethropsU parasitic on an Isaria and that the large eoremium be- 

 longed to the host rather than to the parasite. 



It is very doubtful whether Vuillemin has interpreted Corda 's figures cor- 

 rectly. C. hominis may belong here, C. Puntonii almost certainly does not.

lateral conidiophores terminated by a spore. Sporiferous clusters abundantly 

 branched, producing spherical pulvinate forms. 



Young cultures grown at 20-30° C, adherent, covered with fine or thick 

 arborizations, 2-4 mm. high, in the form of denticulate phialides, 1-2 mm, 

 broad; white when grown in the dark, yellow when gro^vn in the light. Ten- 

 day-old cultures are pulverulent and grayish or greenish because of the spores.

The hyphae having chlamydospores without distinctive characters are 

 branched, tei-minated by aleurospores, truncate at the base with a thick wall, 

 up to 8/A. Sometimes 1 or 2 new aleurospores develop below the terminal one,
