798 MEDICAL MYCOLOGY 



ACREMONIELLA 



Acremoniella Saccardo, Miehelia 1: 270, 1878. 



The type species is Acremonium airum Corda. 



Hyphae repent, simple or branched, hyaline or colored ; conidiophores 

 simple, short, bearing solitary terminal eonidia which are spherical or ovoid, 

 brown, unicellular. 



This genus is predominantly saprophytic, but it has been isolated twice 

 from lesions, once from a small tumor and once from the lungs. It occasion- 

 ally is found as a contaminant. 



Acremoniella Berti Pollacci, Atti 1st. Bot. R. Univ. Pa via 18: 126, 127, 

 PI. 30, 1921. (Case histoiy and cultural characters by Berti, Policlinico Sez 

 Chirurg. 29: 484-489, Figs. 6-9, 1922.) 



Isolated from a small tumor. Granuloma produced in a guinea pig. 



Not obtained pure ; sterile hyphae repent, branched, septate, hyaline, 

 sparse, 3-4/* in diameter; conidiophores hyaline, erect or curved, not cuspidate, 

 15-25|U. long ; eonidia spherical, unicellular, 6-7/t in diameter, brown. Growing 

 with Penicillium Burci Pollacci. 



Grows on Sabouraud glucose ; figures very poor. 



Acremoniella Perinii Pollacci, Rev. Biol. 5: 358-367, 3 figs., 1923. 



Found in sputum from a patient with pulmonary lesion. Pathogenic to 

 guinea pig. 



Tufts at first white then fuscous, diffuse ; sterile hyphae repent, intricate, 

 septate, hyaline or pale ; conidiophores erect, simple, short, 3.5-4/i, in diameter, 

 16-24/x long, septate or continuous, pale, apex obtuse or often inflated. Conidia 

 spherical, granulose, hyaline at first, becoming avellaneous, echinulate, unicellu- 

 lar, acrogenous, 7.8-9.7/i, in diameter. 



Colony grayish at first, then brown. Growth on potato, silky white, with 

 small islands of green, then the surface becomes brown. No growth at 20° C, 

 good at 37° C. At 45° C, a pellucid colony, white, rapidly turning brown. No 

 growth at 55° C. On milk, after 4-5 days, coagulation followed by peptoniza- 

 tion, mycelium brownish with violaceous tint. 



Acremoniella (Acremoniopsis) olivaespora Ciferri & Ashford, Mycologia 

 22: 62-68, 2 figs., 1930. 



A saprophyte isolated from human skin. 



SPOROTRICHUM 



Sporothrichum Link, Mag. Ges. Naturf. Freunde Berlin 3: 12, 13, 1809. 

 The type species is Sporothrichum hadium Link. 



In the original description of the genus eleven species are described as new, and S. 

 virescens and S. abietinum transferred here from Persoon's genus Dematium. Most of the 

 species were bright colored and were found on decaying wood. Since S. hadium is the only 

 one figured and the first to be described, it may be taken as the type of the genus.
