DescriptionOssicaulis lachnopus (Fr.) Contu 182827.jpg |
Ossicaulis lachnopus (Fr.) Contu Image location: Zona da Estrada das Águas Livres, Amadora, Portugal I found two species of the genus Ossicaulis very similar to my specimens: O. lachnopus and O. lignatilis. Photos and microscopy of O. lachnopus can be found in Ref.1. The values for the spores dimensions presented there are: 2.8-3.6 × 2.0-2.6 µm. According to the author this species can be confused with O. lignatilis, the latter having more decurrent gills and bigger spores (see Ref.2). Photos and microscopic data of O. lignatilis can be seen in Ref.3, where for the spores the following dimensions are referred: 4-5.5 × 3-4 µm. Precise values for the dimensions of the spores are beyond the possibilities of my scope, but I get result for average length less then 4.0 µm. In the photo of spores attached the biggest one has 4.3 µm in lenght. In addition, from the photos it is possible to see that the gills are not decurrent. So I believe that this is O. lachnopus. Based on microscopic features
