    Taxon
    The taxonomy of the Leptogium lichenoides complex is revised here based on a morphological, ecological and molecular phylogenetic study. A phylogenetic analysis of phenotypic characters was compared to a phylogeny based on nrITS and β-tubulin data. Using these phylogenies, we concluded that what was commonly recognized as Leptogium lichenoides s.l. encompasses three distinct species. Leptogium lichenoides var. pulvinatum is now recognized as a separate species L. pulvinatum comb. nov. Leptogium aragonii sp. nov., a non-isidiate species with large thalli, is the second species part of this complex, and L. lichenoides s.str., as redefined here, is the only species of this group with isidia. We also found that Leptogium lichenoides s.l. is polyphyletic. Leptogium pulvinatum and L. lichenoides s.str. are more closely related to L. gelatinosum than to L. aragonii. The taxonomic status of L. quercicola is reduced to a variety of L. pulvinatum. Identification key, descriptions and distribution maps are presented for Leptogium aragonii, L. gelatinosum, L. intermedium, L. lichenoides s.str., L. pulvinatum, and L. pulvinatum var. quercicola.

    This paper reports the South American rust fungi Puccinia modiolae and P. platyspora (Pucciniales/Uredinales) as new alien species of the European rust funga. Puccinia modiolae is presently known from Switzerland and Germany, P. platyspora from Switzerland, Germany, and France. The records of P. platyspora are the first ones from outside South America. The specimens were identified by teliospore characters and sequences of the nuclear ribosomal DNA (internal transcribed spacer 2 and domains D1–D2 of the nuclear ribosomal large subunit) and the mitochondrial CO3 (cytochrome c oxidase III) gene. Puccinia modiolae and P. platyspora have been recorded so far in Europe on members of the genera Alcea, predominantly on Alcea rosea, Althaea, and Malva of the Malvaceae, subfam. Malvoideae. Alcea rosea is host of both species and shared also with the common mallow rust, P. malvacearum, allowing for mixed infections. The plant is commonly grown as an ornamental and may play a major role for the spread of the alien Malvaceae rust fungi. It was observed for the first time that P. platyspora can produce spermogonia and aecidium-type aecia, suggesting phenotypic plasticity regarding the formation of spore states. The observed spermogonia mainly remained closed and did not liberate spermatia. They produced telio- and aeciospores besides spermatia in their cavity and eventually converted entirely into telia or, rarely, into aecidium-like sori. Small clusters of aeciospores and peridial cells were commonly found hidden in the telial plectenchyma, and well-developed aecidium-type aecia provided with a peridium developed rarely in the center of mature telia. Spermogonia belonging to group V type 4 were found in P. malvacearum, which is generally supposed to lack spermogonia. Some spermogonia produced only spermatia in their cavity; others formed spermatia and teliospores, and some eventually converted into telia.

  • Image Analysis at Scale with Generative AI
    Item type: Other Publication
    Zhang, Hongyuan; Garcia Otalora, Monica Andrea (2025)
    At ETH Herbaria, the fungal collection curators are working to digitize the historical specimens. Each specimen is accompanied by a label containing essential information relevant to biodiversity research. However, most of these labels have yet to be digitized or cataloged, as the process of transcribing the printed information into digital format is both tedious and time-consuming (See Figure 1). With powerful genAI models such as ChatGPT and Claude, researchers could easily achieve the desired optical character recognition (OCR) output with text prompts in web browsers. However, one would encounter problems while trying to process a batch of images at once, for example, ”Claude hit the max length of this message...”. The restricted context windows in the web browser not only limit the number of uploaded images to a few but also make the model gradually forget the instructions, leading to wrong outputs. Here, we provide a solution for batch image OCR with our code available on GitHub.
