“…Field collection and detailed morphological analysis are necessary in order to understand the development and ecology of these apparently highly diverse tropical microfungi . DNA sequences are not available for most of the representatives of the family, with exception of a few species of Asterina (Hofmann et al, 2010). Molecular analysis of Asterinaceae remains a challenging task due to the reduced hymenia and mostly melanized fungal structures, as well as the presence of other organisms on the same host plant.…”

“…Air-dried material was observed with a Nikon SMZ645 stereomicroscope and a Nikon Eclipse 80i microscope with drawing tube. Microscopic slides, drawings and materials used for scanning microscopy (SEM) were prepared according to Hofmann et al (2010). Type material was loaned from the US National Fungus Collections, Beltsville, Maryland (BPI) and the Plant Protection Research Institute, Pretoria (PREM).…”

New records of species of Asterinaceae with intercalary appressoria infecting plants in Central America and Panama are described and illustrated in detail. New records are Asterolibertia licaniicola on the new host Licania arborea (Chrysobalanaceae), Asterolibertia nodulosa on the new hosts Oxandra venezuelana and Xylopia sp. (Annonaceae), and Cirsosia splendida on the new hosts Chrysobalanus icaco and Hirtella triandra (Chrysobalanaceae). The teleomorph C. splendida is linked for the first time to the asexual morph Homalopeltis chrysobalani based on morphological observation. For the presented fungi an identification key is provided and infection strategies are discussed. Nomenclatural novelties are introduced, Leprieuria radiata becomes a synonym of H. chrysobalani and Asterina nodulifera is recombined into Asterolibertia nodulifera.

“…The 28S (LSU) and 18S (SSU) gene data were combined in the analysis. Sequences were downloaded from GenBank using data from the publications of Schoch et al (2009), Hofmann et al (2010, Wu et al (2011a), Hyde et al (2013) and aligned using MUSCLE (Edgar 2004) and CLUSTALX (v. 1.83) (Thompson et al 1997) and then manually refined and adjusted using BioEdit (Hall 1999). MrModeltest v. 2.2 (Nylander 2004) was used to estimate the best-fitting model for the combined LSU and SSU genes.…”

A new species, Microthyrium propagulensis, collected in Yunnan Province, southwestern China is introduced. The species is typical of Microthyriaceae (Microthyriales) in having superficial thyriothecia with a poorly developed basal layer and a prominent darker central ostiole, bitunicate asci and 1-septate ascospores. It is similar to the generic type, M. microscopicum, but differs in having relatively small ascospores, with two apical cilia, which lie downloads from the ascospore apex at a 45° angle. Phylogenetic analysis based on combined LSU and SSU gene sequence data clearly place this species in Microthyrium, but distinguishes it from Microthyrium microscopicum. This second sequence from a Microthyrium species indicates that the putative sequence of the type of this genus is CBS has been correctly named and supports the distinctiveness of Microthyriales and Microthyriaceae.

“…There have been worldwide concerted efforts by generations of mycologists and plant pathologists to document plant disease-associated fungi (Roger, 1951(Roger, -1954Holliday, 1980;Kohler et al, 1996), although the disease causal agents are probably better known in temperate than tropical regions (Hofmann et al, 2010). Surveys of plant pathogens have resulted in the publication of numerous checklists (Peregrine & Kassim, 1982;Dingley et al, 1981;McKenzie & Jackson, 1986;Hyde & Alcorn, 1993) and more recently many of these have been incorporated into databases such as: USDA, http://nt.ars-grin.gov/ fungaldatabases/fungushost/fungushost.cfm; Database of Plant Disease Names in Japan, www.gene.affrc.go.jp/ databases-micro_pl_diseases_en.php; New Zealand Fungi, http://nzfungi.landcareresearch.co.nz; Fungos relatados em plantas no Brasil -http://pragawall.cenargen.embrapa.…”

OUTLINEPlant pathogenic fungi have long been documented through concerted efforts of mycologists and plant pathologists; these records have served as the basis for regional and countrywide checklists which have since been put into databases listing hosts and associated fungi. They are used by governments and scientists to formulate trade quarantine policies and determine research funding, such as in plant breeding programs and disease control. With the ability to use molecular characters to study the systematics of fungi it is clear that morphologically defined species are often large complexes comprised of genetically and biologically distinct species. Use of molecular techniques to examine species complexes has revealed cryptic species in many important plant pathogenic genera, e.g. Botryosphaeria, Colletotrichum, Fusarium, and Mycosphaerella. It has occurred to such an extent that existing checklists and databases need updating. It is important that the data from these studies, including changes in taxonomy and nomenclature, be incorporated into the databases of plant pathogenic fungi to support accurate plant quarantine decisions. In addition, epitypifying fungi by re-collecting material from type habitats and isolating the organism into pure culture will provide essential materials for systematics studies to further clarify the taxonomy and phylogeny of plant pathogenic fungi. Overall, we conclude that disease lists are likely to be highly outdated and advocate the need for countrywide re-inventory of plant pathogens. As a result of these studies, tools can be developed that use morphological or molecular characters, or both, to promote accurate identification of plant pathogenic fungi.
