TBICHOPHYTONEAE 541 



Sabouraudites villosns Ota & Langeron, Ann. Parasitol. Hum. Comp. 1: 

 328, 1923. 



Producing tinea tonsurans mierosporica, lesions irregular and indefinite 

 in outline, pityriasis very marked, some lesions of neck and face, probably 

 also on Bovidae ; Belgium and Rome, Italy. Inoculable to guinea pig, where 

 the hair is invaded in 10-12 days and heals spontaneously in a month. 



Closterospores abundant, 2-8-celled, very thick-walled; arthrospores and 

 hyphae with branching suggestive of stag horns also present. 



Colony 6 cm. in diameter, center plane, powdery, grayish yellow, light 

 brown with 3-10 radial furrows ; next a zone, about 1 cm. wide, of small vel- 

 vety hills, higher next the center, lower tOAvard the margin, which is composed 

 of fine, immersed hyphae. Pleomorphism in 4 weeks. On Sabouraud con- 

 servation agar, the fine silky disc is cut by radial folds, with a large central 

 umbilicus slightly irregular and quite deep. On potato puree, yellowish, be- 

 coming brown, growth very fine, scarcely visible. On puree of carrot, white 

 velvety margin deeply incised surface of irregular elevations and depressions.

Producing tinea tonsurans mierosporica in Buenos Aires, Argentina. Re- 

 ported common in Argentina, probably also in Uruguay and Brazil. It seems 

 quite probable that reports from Budapest, Hungary, ]\Iainz in Germany, Mon- 

 treal in Canada, and from New York belong to 31. felineum. 



Closterospores very abundant, thin-walled, 4-6-celled, often in groups of 

 12-15 on a single pedicel, 40-54 x 12-15^. Nodular organs and racquet myce- 

 lium present; chlamydospores, aleurospores, and arthrospores present in re- 

 peated subcultures. 



Colony with central umbo, surrounded by a powdery brownish zone often 

 more or less marked by concentric circles with a margin of cottony fringe. 

 On potato, grows very fast as irregular colony, pale brown ochraceous, with 

 a short powderj^ velvet. 



From the descriptions furnished by various authors, it seems probable 

 that M. felineum has been confused frequently with this species.
