Two novel species of Aspergillus that are clearly distinct from all known in section Usti were revealed during a study microfungal communities Spanish caves. The identified this and additional associated with places substrates related to human activities Novel described using data four loci (ITS, benA , caM rpb2 ), morphology basic chemical physiological analyses. Members the thesauricus sp. nov. isolated various substrates, including decaying organic matter, cave air sediment Cueva del Tesoro Cave (the Treasure cave); is represented by twelve isolates most closely recently germanicus . baeticus Gruta de las Maravillas Grotto Marvels); two isolates. An isolate was found Demänovská Peace (Slovakia), suggesting potentially wide distribution micro-organism. ustus pseudoustus Both unable grow at 37 °C, weakly positive, light greenish yellow Ehrlich reaction observed A Unique morphological features alone sufficient distinguish both taxa.
