Coffee (Coffea arabica) plant tissues were surface-sterilized and fungal endophytes isolated using standard techniques, followed by DNA extraction and sequencing of the internal transcribed spacer region (ITS). A total of 843 fungal isolates were recovered and sequenced (Colombia, 267; Hawai’i, 393; Mexico, 109; Puerto Rico, 74) yielding 257 unique ITS genotypes (Colombia, 113; Hawai’i, 126; Me...

Fresh material, type studies and molecular phylogeny were used to clarify phylogenetic relationships of the nine genera Acrocordiella, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria. At first sight, some of these genera do not seem to have much in common, but all were found to belong to the Xylariales, based on their generic type...

Xylariomycetidae (Ascomycota) is a highly diversified group with variable stromatic characters. Our research focused on inconspicuous xylarialean taxa from China, Italy, Russia, Thailand and the United Kingdom. Detailed morphological descriptions, illustrations combined ITS-LSU-rpb2-tub2-tef1 phylogenies revealed 39 our collections belonging to Amphisphaeriales Xylariales. A new family (Appendi...

Threats to our natural areas come from several sources; this problem is all too familiar in northeast Ohio. One of the goals of the Geauga County Park District is to protect high quality natural areas from rapidly encroaching development. One measure of an ecosystem's importance, as well as overall health, is in the biodiversity present. Furthermore, once the species diversity is assessed, this...

The volatiles emitted by agar plate cultures of the xylarialean fungus Hypoxylon invadens were investigated by use of a closed loop stripping apparatus in combination with GC–MS. Several aromatic compounds were found that could only be identified by comparison to all possible constitutional isomers with different ring substitution patterns. For the set of identified compounds a plausible biosyn...
