Baudoinia, a new genus to accommodate Torula compniacensis

Abstract

Baudoinia gen. nov. is described to accommodate Torula compniacensis. Reported originally from the walls of buildings near brandy maturation warehouses in Cognac, France, species of Baudoinia are cosmopolitan colonists of exposed surfaces subjected to large diurnal temperature shifts, episodic high relative humidity and wetting, and ambient airborne ethanol. Morphologically B. compniacensis resembles some anamorphic Mycosphaerellaceae in possessing dark brown, nonseptate or uniseptate conidia with coarsely roughened walls that are borne acropetally in unbranched chains and released by schizolytic dehiscence. Analysis of partial nuclear rDNA SSU sequences positions B. compniacensis in the order Capnodiales and reveals that it is most closely related to the microcolonial genus Friedmanniomyces. Heat resistance is induced by brief sublethal temperature exposure.

“…Some relevant GB sequences included in preliminary analyses are not listed in Table 2. Our SSU data for K. cryptophialidica DAOM 216555 and DAOM 216553 matched published data for the same strains (EF137364, EF137363; Scott et al 2007). Our SSU data for C. perforans CBS 885.95 matched data for the same strain (EF137365; Scott et al 2007).…”

Our SSU data for C. perforans CBS 885.95 matched data for the same strain (EF137365; Scott et al 2007). There are two other GB sequences for this strain, differing in the base call at one position (Y11714) or by single base deletions at multiple positions in the alignment (FJ358305).…”

“…However, based on analyses of the small subunit (SSU) operon of the nuclear rRNA gene (rDNA), Hambleton et al (2002) showed that K. cryptophialidica was phylogenetically close to Coniosporium apollinis Sterflinger and Coniosporium perforans Sterflinger, which were previously found to form a strongly supported sister clade to the Chaetothyriomycetidae (Sterflinger et al 1997. More recent analyses of molecular data support the close relationship of K. cryptophialidica to C. perforans and the Chaetothyriomycetidae (Scott et al 2007;Gueidan et al 2008), while C. apollinis is now recognized to be allied with the Dothideomycetes (Ruibal et al 2009). …”

Polyextremotolerant black fungi: oligotrophism, adaptive potential, and a link to lichen symbioses

“…At least some oligotrophic fungi can use complex phenolic hydrocarbons from the environment as the sole source of carbon and energy. Such fungi are commonly found in unusual habitats, such as biofilters or distilleries (Prenafeta-Boldu et al, 2006; Scott et al, 2007). Several of these species are closely related to human pathogens, therefore it has even been argued that there is a physiological connection between aromatic hydrocarbon assimilation and capability of mammalian infection (Prenafeta-Boldu et al, 2006).…”

Systematics and Evolution

“…The RIF (discussed earlier) contain numerous underdescribed lineages in Capnodiales (Ruibal et al 2009). The rediscovery and analysis of a previously described species, Torula compniacensis (now Baudoinia compniacensis) (Scott et al 2007), has also yielded unexpected additions to this group.
