    Notes: Abstract A method of image enhancement and real-time input of 3-D, microscopic phase objects into a coherent optical pattern recognition system is described. The method consists of directing a low-power laser beam into a microscope objective to produce a real, magnified, coherent image of the specimen under test. The image plane is followed by two successive Fourier transform (FT) planes. In the first FT plane, low and high frequency spatial filters, one of which is photographically produced, are used as pre-processing filters to enhance the image quality. The enhanced signal is imaged from the first FT plane to the second FT plane which contains a matched spatial filter used for specimen identification. The system does not require an expensive incoherent-to-coherent light transducer and in addition, is capable of utilizing both phase and amplitude information from 3-D objects. Examples of results are given.

    Two new classes of Ascomycota: Xylobotryomycetes and Candelariomycetes (2019)

    Description: Phylogenetic analyses of a combined DNA data matrix containing nuclear small and large subunits (nSSU, nLSU) and mitochondrial small subunit (mtSSU) ribosomal RNA and the largest and second largest subunits of the RNA polymerase II (rpb1, rpb2) of representative Pezizomycotina revealed that the enigmatic genera Xylobotryum and Cirrosporium form an isolated, highly supported phylogenetic lineage within Leotiomyceta. Acknowledging their morphological and phylogenetic distinctness, we describe the new class Xylobotryomycetes, containing the new order Xylobotryales with the two new families Xylobotryaceae and Cirrosporiaceae. The two currently accepted species of Xylobotryum, X. andinum and X. portentosum, are described and illustrated by light and scanning electron microscopy. The generic type species X. andinum is epitypified with a recent collection for which a culture and sequence data are available. Acknowledging the phylogenetic distinctness of Candelariomycetidae from Lecanoromycetes revealed in previous and the current phylogenetic analyses, the new class Candelariomycetes is proposed.

    Phylogenetic and taxonomic revision of Lopadostoma (2014)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 32 no. 1, pp. 52-82
    Details
    Publication Date: 2024-01-12
    Description: The genus Lopadostoma (Xylariaceae, Xylariales) is revised. Most species formerly assigned to Lopadostoma do not belong to the genus. Twelve species are herein recognised, of which two are only known from morphology.\nTen species, of which six (L. americanum, L. fagi, L. insulare, L. lechatii, L. meridionale and L. quercicola) are newly described, are characterised by both morphology and DNA phylogeny using LSU, ITS and rpb2 sequences.\nMorphologically, ecologically and phylogenetically Lopadostoma is a well-defined genus comprising exclusively species with pustular pseudostroma development in bark of angiospermous trees. Phaeosperma ailanthi, Phaeosperma dryophilum and Sphaeria linosperma are combined in Lopadostoma. Lopadostoma gastrinum is neotypified and L. turgidum is lecto- and epitypified. Species with asci and ascospores similar to those of Lopadostoma but having perithecia immersed in wood, particularly those of Lopadostoma subg. Anthostomopsis have been determined to be unrelated to the genus. DNA data confirm that Anthostoma is unrelated to Lopadostoma. Its type and currently only confirmed species Anthostoma decipiens belongs to Diatrypaceae. DNA data also show that L. pouzarii and Barrmaelia macrospora are unrelated to Lopadostoma. A commentary is provided for names in Lopadostoma and those names in Anthostoma that may be putative species of Lopadostoma based on their protologues. Anthostoma insidiosum is an older name for Anthostomella (Diatrype) adusta.
