Fossil arbuscular mycorrhizae from the Early Devonian
(Mycological Society of America, 1995-01-05)The 400 million-year-old Rhynie chert has provided a wealth of information not only of early land plants, but also of the fungi that inhabited this paleoecosystem. In this paper we report the first unequivocal evidence ... -

(Akademie Verlag, 2007-01-01)The known fauna of Early Miocene (Burdigalian) drywood termites (Isoptera: Kalotermitidae) in amber from the Dominican Republic is revised. To the previously described Cryptotermes yamini KRISHNA & BACCHUS, four species ... -
A remarkable new leaf-cutter bee from Thailand (Hymenoptera: Megachilidae)
(Akademie Verlag, 2006-01-01)A remarkable new species of leaf-cutter bee, Megachile trichorhytisma ENGEL sp. n., is described and figured from two males collected in northern Thailand. The species is placed in a new subgenus, Aethomegachile ENGEL & ... -
Molecular Variation within and among Species of Harpellales
(Mycological Society of America, 2001-01-01)Intra- and interspecific variation of the nuclear ribosomal internal transcribed spacers (ITS) of 77 Smittium isolates and related genera was studied using RFLP. Due to the sequence and length variation encountered, the ... -
An orthognathine weevil of the genus Mesocordylus in Dominican amber (Coleoptera: Curculionoidea: Dryophthoridae)
(Akademie Verlag, 2009-01-01)A new orthognathine weevil species (Curculionoidea: Dryophthoridae), Mesocordylus longiscapus sp. n., is described and illustrated from Early Miocene Dominican amber. It represents the first amber fossil record of Mesocordylus ... -

Weissistachys Kentuckiensis: A new Name for Weissia Kentuckiense Rothwell and Taylor
(University of Chicago Press, 1971-12-01)The generic name Weissia Roth well and Taylor is determined to be a later homonym of Weissia Hedwig. Weissia Rothwell and Taylor is therefore renamed Weissistachys, and the appropriate name transfer is made for the type ... -
A Systematic and Developmental Analysis of Arthropitys deltoides Sp. Nov.
(University of Chicago Press, 1983-06-01)Arthropitys deltoides sp. nov. is described from Pennsvlvanian sediments of southeastern Kentucky. The axes are characterized by parenchymatous interfascicular rays that broaden conspicuously toward the periphery of the ... -
Cuticular Features and Epidermal Patterns in the Genus Araucaria de Jussieu
(University of Chicago Press, 1978-12-01)The cuticular organization and epidermal features of le aves from the four sections of the genus Araucaria, growing under similar environmental conditions, were studied by scanning electron microscopy. Cuticles from these ... -
Studies of Paleozoic Calamitean Cones: Weissia Kentuckiense Gen. et Sp. Nov.
(University of Chicago Press, 1971-09-01)The recent discovery of a new petrified fructification from the Lewis Creek coal ball locality in eastern Kentucky adds to our knowledge of the structure and diversity of c alamitean cones. The incomplete specimen measures ... -
Telangiopsis Gen. Nov., an Upper Mississippian Pollen Organ from Arkansas
(University of Chicago Press, 1971-03-01)Telangiopsis arkansanum is described from compressed synangiate pollen organs borne terminally on a monopodially branched system of slender axes. The specimens occur in a fine-grained shale unit of the Wedington sandstone ... -
Geotrichites glaesarius, a conidial fungus from Dominican amber
(Mycological Society of America, 1985-01-05)Geotrichites glaesarius, a new fungal anamorph, is described from Dominican amber of late Oligocene or early Miocene age. A well-developed mycelium is present on the surface of an arachnid cadaver; hyphae are not present ... -
Studies of Paleozoic Seed Ferns: Additional Studies of Microspermopteris aphyllum Baxter
(University of Chicago Press, 1986-03-01)The genus Microspermopteris is characterized as a small lyginopterid pteridosperm with a pentarch protostele, irregular cortical ridges, and multicellular trichomes. We describe the frond architecture and variability among ... -

Geotrichites glaesarius, a Conidial Fungus from Tertiary Dominican Amber
(Mycological Society of America, 1985-01-01)Geotrichites glaesarius, a new fungal anamorph, is described from Dominican amber of late Oligocene or early Miocene age. A well-developed mycelium is present on the surface of an arachnid cadaver; hyphae are not present ... -
Morphological and Ultrastructural Studies of Plant Cuticular Membranes. I. Sun and Shade Leaves of Quercus velutina (Fagaceae)
(University of Chicago Press, 1990-12-01)Sun and shade leaves of Quercus velutina Lam. were evaluated with respect to differences in gross anatomy, morphology, and cuticle (cuticular membrane (CM|) ultrastructure and micromorphology. Sun leaves are smaller, with ... -
Studies of Paleozoic Fungi IV: Wall Ultrastructure of Fossil Endogonaceous Chlamydospores
(Mycological Society of America, 1985-01-01)Fossil endogonaceous chlamydospores are described from the aerial axes and roots of several Paleozoic plants preserved in calcilutite nodules and calcareous coal balls. Specimens come from six Paleozoic localities extending ... -
Wood Decay in Silicified Gymnosperms from Antarctica
(University of Chicago Press, 1986-03-01)Gymnospermous secondary xylem degraded by wood-decaying fungi was examined in silicified fossils from Antarctica. AraucarioxyIon-type wood from the Triassic and specimens of Vertebraria from the Permian demonstrate similar ... -
Devonian Fungi: Interactions with the Green Alga Palaeonitella
(Mycological Society of America, 1992-11-01)This paper describes three new taxa of fossil aquatic fungi preserved in 400-million-year-old Lower Devonian Rhynie Chert. All of the fungal morphotypes are attached to cells of the green alga Palaeonitella cranii. ... -
