The Aspergillus viridinutans complex includes morphologically similar, soil-inhabiting species. Although its species boundaries have not been fully defined, many isolates from the complex have been isolated as opportunistic human and animal pathogens. In the present study, these species were dominant in spoil sites subjected to various types of reclamation management after coal mining. These species were characterised using two different PCR-fingerprinting methods, sequence data from the β-tubulin (benA) and calmodulin (caM) genes, macro- and micromorphology (optical and scanning electron microscopy), maximum growth temperatures and mating experiments. In addition, RNA polymerase II gene (RPB2), actin (act1) and ITS sequences were deposited for the ex-type isolates of newly described species. The mating experiment results, phylogenetic analyses and ascospore morphology suggested the presence of five species in the A. viridinutans complex. Aspergillus aureolus (syn. Neosartorya aureola) was the only homothallic species. Three species, A. felis, A. udagawae (syn. N. udagawae) and A. wyomingensis sp. nov., were heterothallic and their morphologically distinguishable teleomorph was induced by systematic mating experiments. Aspergillus viridinutans s. str. seems to be a very rare species and was represented only by the ex-type isolate in which the MAT1-1 locus was amplified. Aspegillus viridinutans and A. aureolus were typified in accordance with the rules of the new botanical code. Other species outside the A. viridinutans complex isolated from the reclamation sites were A. fumigatiaffinis and A. lentulus as well as two new sister species, A. brevistipitatus sp. nov. and A. conversis sp. nov. which were closely related each to other and to N. papuensis. Both new species are phylogenetically distant from all anamorphic species and resemble A. brevipes, A. duricaulis and A. unilateralis in micromorphology and are distinguishable from each other by the slower growth of A. conversis on all tested media. Interestingly, no isolate from the reclamation sites represented A. fumigatus s. str. which is usually reported as the dominant species from the section Fumigati in soil.

Three new species ofEupenicillium are described from soils from the western United States. They areE. idahoense sp. nov.,E. tularense sp. nov., andE. lasseni sp. nov. The conidial stages are new species ofPenicillium.

A new variety ofAspergillus fischeri, var.thermomutatus, is described. The new variety differs from previously known varieties ofA. fischeri in having many vesicles set at an angle to the conidiophore when cultures are incubated at 22° C. The vesicles are upright when cultures are incubated at 37° C. The ascigerous state is like that ofA. fischeri var.fischeri.

A centrifugation technique employing sucrose density gradient columns has been developed for separating fungus spores from soil mineral particles. Four pyrenomycetes plus a number of sterile isolates have been obtained by the use of this technique. The technique may be applicable to other types of fungi producing large, readily identifiable spores.
