“…As part of our studies on Xylohypha bantiana (Saccardo) McGinnis, Padhye, Borelli et Ajello (9-11), we obtained four clinically significant isolates of a dematiaceous hyphomycete that resembled X. bantiana. In fact, one of the isolates had been previously confused with X. bantiana (8). These isolates differed from X. bantiana in that they formed short, unbranched to sparsely branched chains of acropetally arranged blastoconidia that arose laterally or terminally from poorly differentiated conidiophores.…”

Xylohypha emmonsii Padhye, McGinnis et Ajello is described as a new dematiaceous opportunistic pathogen of humans and lower animals. This hyphomycete differs from X. bantiana (Saccardo) McGinnis, Padhye, Borelli et Ajello by its inability to grow at 40°C and by the development of short chains of asymmetrically bent to ellipsoid blastoconidia. In brain tissue of mice, experimentally infected with X. emmonsii, the host response to the invading fungus was similar to that observed in mice infected with X. bantiana. In tissues X. bantiana occurred predominantly as long, septate hyphae, in contrast to X. emmonsii, which was more polymorphic.

“…chlamydosporum has the same partial sequence as C. trichoides and proved identical in DNA/DNA reassociation experiments (Table 2L The variety was originally described on the basis of the presence of thick-walled chlamydospores [35]. Similar chlamydospores are known in other strains of C trichoides [32,36], Cludophialophora arxii [38] and in CIadosporium carrionii [31]. The occurrence of chlamydospores appears to be of physiological rather than of taxonomic interest.…”

“…conidial size and pigmentation and branching patterns of conidial chains, are all found to be highly dependent on cultural conditions. Xylohypha emmonsii is known from subcutaneous rather than systemic phaeohyphomycosis and it is found in tissue with irregular yeast-like cells rather than cylindrical hyphae [17,27,38]. The histopathological difference may be explained by a higher degree of innate cellular immunity in subcutaneous tissue.…”

Phylogenetic relationships of human-pathogenicCladosporium(Xylohypha) species inferred from partial LS rRNA sequences

and ¶Unit6 de Biologie Cellulaire Marine, URA 6 71-CNRS Paris 6, Station Zoologique 06230, Villefranche sur Mer, FranceThe controversy about the appropriate taxonomic placement of agents of subcutaneous and systemic mycoses in either Cladosporium or Xylohypha, both genera characterized by conidia being produced in dry, acropetal chains, was addressed with partial sequencing of LS ribosomal RNA. Observation of catenate anamorphs in species of Capronia (Ascomycotina, Herpotrichiellaceae), a genus which also has anamorphs in Exophiala, suggested the possibility of a close interrelationship of all humanassociated taxa. To test this hypothesis, partial sequences of 43 strains of Cladosporium/Xylohypha were analysed. Human-pathogenic and saprophytic Cladosporium species were found to be phylogenetically distinct from each other and, on the basis of known teleomorph relationships, were considered to be anamorphs of Herpotrichiellaceae and Mycosphaerellaceae, respectively. They should therefore be classified in different anamorph-genera; Cladosporium being restricted to plantassociated species. A relatively large proportion of the Herpotrichiellaceae is presumed to be animal-associated. The black yeast genus Exophiala was also confirmed to be of herpotrichiellaceous relationship. The genus Xylohypha is unrelated.

“…When we requested the loan of the nomenclatural type for C. trichoides var. chlamydosporum, we learned that one had not been prepared (6). Thus, this name is invalid as it is not in compliance with Articles 9.5 and 37.1.…”
