Abstract
Myceliophthora guttulata sp. nov. is described and illustrated based on strains isolated from soil in China. This species is thermophilic with optimal growth temperature of 40–45 °C, and minimum growth temperature of 25 °C. Morphologically, this species is characterized by smooth, guttulate, pyriform to obovoid blastoconidia born directly on the side of hyphae, on long or short pedicels or in groups of 1–4 on ampulliform swellings. Phylogenetic analysis based on multi-locus alignment of internal transcribed spacer (ITS), elongation factor 1-alpha (EF1-α) and RNA polymerase II subunit (RPB2) regions showed that M. guttulata clustered within the genus Myceliophthora, and is closely related to four thermophilic species, i.e. M. fergusii, M. thermophila, M. heterothallic, and M. hinnulea.
