? 2021 Elsevier B.V.The authors regret having misclassified the endophyte Talaromyces fugus isolated from Epilobium angustifolium, that should be T. fusiformes and not marneffei. Our article needs therefore correction. Our attention to this error was raised by this note sent to the Editor of Fitoterapia by Qian Du Duqian and Franklin Wang-Ngai Chow: We are writing to express our thoughts on the research article entitled “A norbisabolane and an arabitol benzoate from Talaromyces marneffei, an endophytic fungus of E. angustifolium”, published in Fitoterapia 153 (2021), 104,948. The author claimed that they have isolated a strain of Talaromyces marneffei from the plant E. angustifolium, based on the morphology on PDA plate and BLAST analysis of the of the DNA sequences from the ITS1–5.8S-ITS2 ribosomal DNA gene region. The sequence for their isolate had been deposited in the GenBank with the accession no. MK849927. T. marneffei (formerly Penicillium marneffei) is indeed a human pathogenic dimorphic fungus causing talaromycosis (formerly penicilliosis) in both immunocompetent and immunocompromised patients, including cancer, HIV positive, organ transplant, and autoimmune diseases patients. T. marneffei grows as mycelial form with red diffusible pigment below 30 °C and grow as yeast form when it is above 30 °C. Although researchers have spent years to look for the environmental reservoir, the only confirmed reservoir of T. marneffei is bamboo rat (Rhizomys). Although the authors claimed that their isolate from “E. angustifolium” is T. marneffei, the culture plate photo in the graphical abstract did not show characteristics red diffusible pigment. We therefore BLAST the sequence of MK849927 and limit to theagainst the rRNA/ITS database of “Internal transcribed spacer region (ITF) from Fungi type and reference material”“Sequences from type material”. The result returns 99.66% sequences similarity to “Talaromyces fusiformis strain CBS 140637” (accession no. NR_169911.1) instead ofwhile there is only 95.54% sequence similarity to “Talaromyces marneffei CBS 388.87” (accession no. NR_103671.2). We believe that the authors were misled by incorrectly deposited annotated ITS sequences from non-type material sequence database previously. We further investigate if the morphology of their isolate is similar to T. fusiformis by comparing the culture photos of this article to Fig. 12 of the article “New Talaromyces species from indoor environments in China” PMID: 28070136, and found that it is indeed very similar to T. fusiformis. All together with the ITS sequence and the morphology, we believe that their isolate was indeed T. fusiformis but not T. marneffei.
