“…The two species, T. flavus and T. stipitatus, belonging to the section Talaromyces have been reported from India. T. flavus, which produces vermiculine, an antiprotozoal antibiotic (Jones et al, 1984) has been isolated from air, soil, textile, animal dung, seeds, roots, and leaves of plants in Delhi, Kerala, Orissa, Tamil Nadu, Uttar Pradesh, Uttarakhand, and West Bengal states of India (Basu, 1951;Benjamin, 1955;Chattopadhyay and Gupta, 1959;Gupta et al, 1966;Mukerjee, 1966;Saxena et al, 1969). Similarly, T. stipitatus, which produces a signature stipitatic acid along with the deadly mycotoxins, duclauxin, talaromycins, and botryodiploidin (Frisvad et al, 1990), has been isolated using soil, leaf, and litter from Gujarat, Karnataka, Kerala, Madhya Pradesh, Uttar Pradesh, Uttarakhand, and West Bengal (Rai and Tewari, 1961, Rai et al, 1969, Sarbhoy, 1965.…”

In this study, Talaromyces qii belonging to the section Talaromyces is reported as a new record from India based on the morphology and phylogenetic analyses of four gene datasets viz. ITS, BenA, CaM, and rpb2. This is the second report of this rare Talaromyces species from across the world. Phylogenetically, the Indian strain T. qii (NFCCI 5151) formed a sister lineage to the type species T. qii (AS3 15414) due to the sequencing error in the type. The quality assessment of the four gene sequences derived from all type strains of section Talaromyces in this study evaded the proposal of a redundant novelty in this section, aligning the Indian strain NFCCI 5151 along with T. qii (AS3 15414). Morphology of type strain T. qii (AS3 15414) and T. qii (NFCCI 5151) are mostly identical, viz. elongated, biverticillate-symmetrical conidiophores, acerose phialides, and ellipsoidal or sub-globose conidia with echinulate ornamentation. However, the Indian strain has longer conidiophores and a larger conidia size than type strain T. qii and T. thailandensis. This study resolved the phylogeny of a new record of Talaromyces qii in the section Talaromyces from India through the most modern taxonomic approaches.
