A detailed description, illustrations, and discussion concerning morphologically similar and phylogenetically closely related species are provided for each species. From light and scanning electron microscopy observations C. diebuensis is characterized by the nailhead to peltate aeciospores, with separated stilt-like base. C. zhuoni- ensis differs from other known Chrysomyxa species in the annulate aeciospores with distinct longitudinal smooth cap at ends of spores, as well as with a broken, fissured edge. Analysis based on internal transcribed spacer region (ITS) partial gene sequences reveals that the two species cluster as a highly supported group in the phylogenetic trees. Correlations between the morphological and phylogenetic features are discussed. Illustrations and a detailed description are also provided for the aecia of C. succinea in China for the first time. Keywords: aeciospores, molecular phylogeny, spruce needle rust, taxonomy Introduction Picea asperata Mast.is native to western China, widely distributed in Qinghai, Gansu, Shaanxi and western Sichuan. -

The host was identified initially as a leaf-cutting ant (Atta cephalotes, Camponotus sericeiventris Attini, Myrmicinae). However, a critical examination of the original illustration reveals that the host is the golden carpenter ants carpenter ant, Camponotus sericeiventris (Camponotini, Formicinae). Because the holotype is no longer extant and epitype the original diagnosis lacks critical taxonomic information – specifically, on ascus and ascospore morphology – a new Ophiocordyceps type from Minas Gerais State of south-east Brazil is designated herein. A re-description of the fungus is provided and phylogeny a new phylogenetic tree of the O. unilateralis clade is presented. It is predicted that many more species of zombie- ant fungi remain to be delimited within the O. unilateralis complex worldwide, on ants of the tribe Camponotini. Published online: 15 December 2017.

As part of the All Taxa Biotic Inventory currently being conducted in the Great Smoky Mountains National Park, samples of woody debris in freshwater and terrestrial habitats as well as leaves and soil organic matter in terrestrial habitats were collected and studied to detect the presence of hyphomycetes. Sixty hyphomycetes are reported here, and three new species are described and illustrated. Eleven species are new records for the USA, and fifteen species are new records for the park. Key words: anamorph, fresh water, mitosporic, systematics, wood Introduction An All Taxa Biotic Inventory (ATBI) is currently underway in the Great Smoky Mountains National Park (GSMNP), USA. In conjunction with a non- profit organization, Discover Life In America (DLIA), the aim of the ATBI is to inventory all life forms in the park. Goals of the ATBI are to determine: 1) what species exist in the park; 2) where the species occur in the park; and, 3) the roles species play in the park ecosystems (Sharkey, 2001). -

Classificatie Van Planten – Nieuwe Inzichten En Gevolgen Voor De Praktijk
B268_dendro_bin 03-11-2009 10:32 Pagina 4 Classificatie van planten – nieuwe inzichten en gevolgen voor de praktijk Ir. M.H.A. Hoffman Er zijn ongeveer 300.000 verschillende (hogere) plantensoorten, die onderling veel of weinig op elkaar lijken. Vroeger werden alle planten- soorten afzonderlijk benaamd, en was niet duidelijk hoe deze soorten ver- want waren. Tegenwoordig worden soorten conform het systeem van Lin- naeus ingedeeld in geslachten. Soorten die sterk verwant zijn aan elkaar hebben dezelfde geslachtsnaam. Geslachten worden op hun beurt weer ingedeeld in families en die op hun beurt weer in ordes, enzovoort. Op deze manier kent het plantenrijk een hiërarchisch indelingsysteem, met verwantschap als basis. Sterke verwantschap is meestal ook zicht- baar aan de uiterlijke gelijkenis. Soorten die veel op elkaar lijken en verwant zijn zitten in dezelfde groep.Verre verwanten zitten ver uit elkaar in het systeem. Om een plant goed te kunnen benamen, moet dus eerst uitgezocht worden aan welke andere soorten deze verwant is. Tot voor kort werd de gelijkenis van planten zen. Deze nieuwe ontwikkeling is van grote voornamelijk bepaald aan uiterlijke kenmerken invloed op de taxonomie en op het classificatie- van bijvoorbeeld bloem en blad.

HYDRANGEA CARE Hydrangeas Can Be Confusing When It Comes to Requirements and Especially Pruning
HYDRANGEA CARE Hydrangeas can be confusing when it comes to requirements and especially pruning. We’ve broken down the hydrangeas we carry into three basic groups to easily explain the differences. HYDRANGEA ARBORESCENS (SMOOTH HYDRANGEA) Smooth hydrangeas are some of the easiest to grow and lowest maintenance hydrangeas. They are known for their large flower heads, sturdy stems, and great cut flowers. They almost always bloom on new wood which means they should be pruned in late fall. Smooth hydrangeas can be cut back 6-8” from the ground in late fall if desired. Includes: Annabelle & Invincible Spirit II (and others) HYDRANGEA MACROPHYLLA (BIGLEAF HYDRANGEA) Bigleaf or “ever-blooming” hydrangeas are desired for their deep green leaves, numerous blooms, and easy care. Bigleaf hydrangeas bloom on both new and old wood, but most of their summer blooms occur on wood formed the previous summer. To encourage new blooms throughout the summer, remove spent blooms as soon as they’re done flowering. The sooner this is done, the longer the plant will be allowed to recover and set new buds for the next season. This will encourage larger and more numerous blooms. Bigleaf hydrangeas prefer a location where they receive morning sun (about 4 hours) but are shaded from the afternoon sun. If they are planted in an area with total shade, it is not likely that they will bloom. Includes: Endless Summer, Blushing Bride, Seaside Cape Cod, Grateful Red, & Bloomstruck (and others) HYDRANGEA PANICULATA (GRANDIFLORA HYDRANGEA) Grandiflora hydrangeas are some of the most commonly planted hydrangeas in this area. They are tolerant of numerous conditions and are easy to grow. -

Phytopathology Research (2020) 2:35 https://doi.org/10.1186/s42483-020-00076-5 Phytopathology Research REVIEW Open Access Fungal species associated with apple Valsa canker in East Asia Xuli Wang1,2, Cheng-Min Shi3, Mark L. Gleason4 and Lili Huang1* Abstract Since its discovery more than 110 years ago, Valsa canker has emerged as a devastating disease of apple in East Asia. However, our understanding of this disease, particularly the identity of the causative agents, has been in a state of confusion. Here we provide a synopsis for the current understanding of Valsa canker and the taxonomy of its causal agents. We highlight the major changes concerning the identity of pathogens and the conflicting viewpoints in moving to “One Fungus = One Name” system for this group of fungal species. We compiled a list of 21 Cytospora species associated with Malus hosts worldwide and curated 12 of them with rDNA-ITS sequences. The inadequacy of rDNA-ITS in discriminating Cytospora species suggests that additional molecular markers, more intraspecific samples and robust methods are required to achieve reliable species recognition. Keywords: Perennial canker, Cytospora, Species recognition, Nomenclature, Malus Background Valsa canker has emerged as a global threat to apple Apple (Malus domestica Borkh) is one of the most industry (CABI and EPPO 2005; EPPO 2020), and is widely planted and nutritionally important fruit crops in particularly destructive in East Asia (Togashi 1925; Uhm the world (Cornille et al. 2014; Duan et al. 2017).

INNS are increasingly abundant in Great Britain and in Europe generally and their impact is rising. Hence, INNS are the subject of considerable concern in Great Britain, prompting the development of a Non-Native Species Strategy and the formation of the GB Non-Native Species Programme Board and Secretariat.
