A reassessment of two freshwater ascomycetes, Ceriospora caudae-suis and Submersisphaeria aquatica

Ceriospora caudae-suis and Submersisphaeria aquatica, two freshwater pyrenomycetes reported infrequently since their original description, occur commonly on submerged woody debris in the USA. Based on analyses of 28S rDNA sequence data and morphology, both species belong in the Annulatascaceae. Ceriospora caudae-suis is transferred to Pseudoproboscispora, a genus in the Annulatascaceae with similar overall morphology and ecology. Submersisphaeria aquatica is redescribed and illustrated based on additional collections.

The teleomorph of Cristulariella moricola

The teleomorph of Cristulariella moricola, a leaf spotting fungus, is described as a new genus and species, Grovesinia pyramidalis. It was produced in vitro after a cold treatment of 4-6 months at 4 C and subsequent incubation at 15 C and a 14-h photoperiod. Mycelial inoculations using a culture of ascospore origin produced typical bulls-eye or zonate lesions and pyramidal conidia on kidney bean confirming the teleomorphic-anamorphic connection.

Boerlagiomyces websteri, a new ascomycete from fresh water

An unusual loculoascomycete with super? ficial, setose ascomata, two-spored, fissitunicate asci and large, dictyosporous ascospores surrounded by a gelatinous sheath is described in the genus Boerlagio- myces (Tubeufiaceae, Pleosporales). This species is known only from rivers in lower latitudes in North America and may be a warm water species.

Illinois Fungi 10. Development, Morphology, and Taxonomy of Cristulariella Pyramidalis

Cristulariella pyramidalis Waterman & Marshall (1947) was first described as associated with a leaf spot on boxelder (Acer negundo L.), sugar maple (A. saccharum Marsh.), and sycamore maple (A. pseudoplatanus L.). Originally this fungus was thought to be pathogenic only on species of Acer, since no other host genera were reported until 15 yr later. To date, it is apparent that C. pyramidalis infects a wide variety of woody and herbaceous plants distributed in the central and eastern United States (Neely and Evers, 1976; Trolinger, 1975; Trolinger et al., 1978) and Japan (Yokoyama and Tubaki, 1974). Some of its hosts include economically important agricultural crops such as peanut (Arachis hypogaea L.) (Smith, 1972), Fordhook lima bean (Phaseolus lunatus L. var. Fordhook) (Baniecki and Young, 1974), pecan (Carya illinoiensis (Wangenh.) C. Koch) (Latham and Amling, 1968), and black walnut (Juglans nigra L.) (Neely et al., 1976). Cristulariella pyramidalis is similar morphologically and physiologically to Bowens (1930) description of the type species C. depraedens (Cke.) Hoehn. Waterman and Marshall (1947) emended the description of Cristulariella to include C. pyramidalis, a new species with pyramidal heads. Von Arx (1974) placed the genus Cristulariella in synonomy with the genus Myrioconium. He implied that Cristulariella depraedens is a spermatial state of species of either Sclerotinia Fuckel, Ciboria Whetzel, or Rustroemia Karst. We concur with Redhead

Revision of Torula Species. Pseudoaegerita Corticalis, Taeniolina Deightonii and Xylohypha Bowdichiae

The type materials of Torula corticalis and T. bowdichiae are not congeneric with Torula as redefined. A new genus Pseudaegerita is erected to accommodate T. corticalis. The new combination Xylohyp...

A NEW SPECIES OF BYSSOTHECIUM (LOCULOASCOMYCETES) FROM WOOD IN FRESH WATER

The morphology and development of Byssothecium flumineum, a new loculoascomycete in the Dacampiaceae from submerged wood, was studied. This species is characterized by medium-sized, ovoid to obpyriform ascomata with a relatively wide peridium. Hamathecium consists of gel-coated cellular pseudoparaphyses interspersed among abundant basal and slightly lateral asci. Ascospores are 3-septate, brown with slightly lighter end cells and verruculose. Byssothecium flumineum occurs frequently on woody debris in midwester streams and decomposes wood by soft rot activity.

Aquadiscula appendiculata, a new genus and species of discomycetes from leaves submerged in a freshwater swamp

Aquadiscula appendiculata was isolated from leaves of Acer rubrum L. submerged in an Illinois freshwater swamp. This species is characterized by 1to 2-celled, hyaline ascospores with a mucilaginous appendage at one end. Apothecia develop in water and are composed of relatively undifferentiated tissues.
