    Erwin Gruber commented on an older version of File:Equisetum hyemale in spring.jpg:

    In some part of the image It looks as if there was some parasitic Stamnaria americana Massee & Morgan, restricted to growing solely on Equisetum hyemale, or Stamnaria laetissima (Cesati) ined.! (me, curator), inhabiting Eq. subgen. Hippochaete, which of i identified the subsp. tenuispora ined.! (me, curator) from locations in NW-Russia and S Finland. The ineditioned taxa are pending for the attended publication, noted associations are tentative since i may not see the spots clearly enough. Addendum: I am sure to have seen any parasitic Stamnaria sp. in small spots, but may not identify the species and add it being associated with its host, since there are no entries for those species yet, i will change this within short!

    Erwin Gruber commented on "Image of an unknown taxon":

    The imaged individual may! in fact be Polystichum aculeatum, but as well some other Polystichum sp., this may not be proved by the small image!

    Erwin Gruber commented on an older version of File:Pinus cembra.jpg:

    I would like the author of this pinecone-image taken on 15.08.2004 to tell where he picked it in Austria, please tell us the source if reading this. The origin was added by author at the source: Swiss Pine (Pinus cembra) cone and foliage, originally harvested south of Hochmölbing, Totes Gebirge, Austria.
