Ophiostoma spp. associated with pine- and spruce-infesting bark beetles in Finland and Russia Naturalis
Linnakoski, R.; Beer, Z.W. de; Ahtiainen, J.; Sidorov, E.; Niemelä, P.; Pappinen, A.; Wingfield, M.J..
Baobabs (Adansonia spp.) are iconic trees, known for their immense size, strange forms, sources of food and as the subjects of myths and mysteries. It is thus surprising that little is known regarding the fungi that infect these trees. During a survey to determine which wound infecting fungi occur on baobabs, synnematous structures were observed and Graphium-like isolates were obtained. Culture characteristics and micro-morphology, together with DNA sequence comparisons for the SSU rRNA, rRNA-ITS and TEF-1α gene regions were used to characterise these fungi. These data revealed three novel Graphium spp. and these are described as G. adansoniae, G. madagascariense and G. fabiforme.

Ophiostomatoid fungi associated with the spruce bark beetle Ips typographus, including 11 new species from China Naturalis
Chang, R.; Duong, T.A.; Taerum, S.J.; Wingfield, M.J.; Zhou, X.; Yin, M.; Beer, Z.W. de.
Ips typographus (Coleoptera, Scolytinae) is a spruce-infesting bark beetle that occurs throughout Europe and Asia. The beetle can cause considerable damage, especially when colonized trees are stressed and beetle populations increase. Although some studies have shown that populations of I. typographus in Europe, China and Japan are genetically distinct, these populations are biologically similar, including a strong association with ophiostomatoid fungi. To date, only two Leptographium spp. have been reported from the beetle in China, while 40 species have been reported from Europe and 13 from Japan. The aims of this study were to identify the ophiostomatoid fungal associates of I. typographus in north-eastern China, and to determine whether the fungal...

Redefining Microascus, Scopulariopsis and allied genera Naturalis
Sandoval-Denis, M.; Gené, J.; Sutton, D.A.; Cano-Lira , J.F.; Hoog, G.S. de; Decock, C.A.; Wiederhold, N.P.; Guarro, J..
The genera Microascus and Scopulariopsis comprise species commonly isolated from soil, decaying plant material and indoor environments. A few species are also recognised as opportunistic pathogens of insects and animals, including humans. In the past, the taxonomy of these fungi has been based on morphology only. With the aim to clarify the taxonomy and phylogeny of these fungi, we studied a large set of clinical and environmental isolates, including the available ex-type strains of numerous species, by means of morphological, physiological and molecular analyses. Species delineation was assessed under the Genealogical Phylogenetic Species Recognition (GCPSR) criterion using DNA sequence data of four loci (ITS region, and fragments of rDNA LSU, translation...
