Annellophores in Torula jeanselmei

In a preliminary report of fungi isolated from pulp samples collected in New York State (12), 40 cultures of an imperfect fungus were assigned to Margarinomyces heteromorpha (Nannf.) Mangenot. My isolates are identical to Mangenot's culture isolated from wood in France (8). This species, under the original name Trichosporium heteromorphum Nannf., was reported abundant in wood pulp in several paper mills in Sweden (10). However, a study of slides of the paratype of T. heteromorphum, made after the publication of the preliminary report, revealed that T. heteromorphum Nannf., with numerous sclerotial bodies and M. heteromorpha (Nannf.) Mangenot, lacking these structures, represent two distinct species. Furthermore, phialides bearing collarettes were found in the slides of the paratype of T. heteromor? phum which was consequently redescribed and transferred to Phialophora by Wang (13). While studying M. heteromorpha sensu Mangenot, I found it to be identical to Phialophora jeanselmei (Langeron) Emmons. The latter fungus, transferred from Torula by Emmons, is the etiologic agent of a rare human disease known as mycetoma (5, 7). In my preliminary report of the fungi in pulp samples (12), the name M. heteromorpha was used because the collarettes typical of the genus Phialophora were not observed in any cultures studied. Apparently, the earlier, valid name for the fungus reported by Mangenot and myself as M. hetero? morpha is P. jeanselmei. In his paper on the black yeasts, W. B. Cooke (4) has already considered M. heteromorpha (Nannf.) Mangenot sensu Mangenot as synonym of P. jeanselmei. This paper adds hitherto unrecorded details of the sporogenous cells of P. jeanselmei and offers a reason for using the original name Torula jeanselmei Langeron.
