“…In Graphium scolytodis indeterminate synnemata with mononematous conidiophores bearing conidia of the shape and size similar to those known from determinate synnemata of G. penicillioides aggregate (Okada et al 2000, Cruywagen et al 2010 are present. This is congruent with the situation in G. penicillioides, where degenerate synnemata or mononematous conidiophores are also present, with conidiophores and conidia basically identical in shape to those found in synnemata, but much more variable in conidial dimensions (Okada et al 2000).…”

“…SSU rDNA sequence (AM267260) has the highest similarity (1638/1652 bp, 99.2%) with G. penicillioides AB038423. A detailed characterisation, including phylogeny and comparison with related species, was presented by Kolařík & Hulcr (2009) and Cruywagen et al (2010). The latter study provides a comparison of Graphium species with known DNA data and places G. scolytodis into the genus Graphium, close to G. penicillioides and G. basitruncatum.…”

Geosmithia cnesini sp. nov. is a dominant symbiont of the ambrosia beetle Cnesinus lecontei collected from Croton draco in Costa Rica. This fungus is characterised by whitish colonies and penicillate conidiophores with extraordinary large catenate conidia. Graphium scolytodis sp. nov. is described here from the galleries of ambrosia beetle Scolytodes unipunctatus collected from the trunk of a fallen Cecropia angustifolia tree in Costa Rica. This species does not seem to be a nutritional mutualist but rather a stable associate of unknown function. It produces mononematic conidiophores only and is related to Graphium penicillioides.

“…Ceriani-Nakamurakare et al (2016), through a culture-dependent approach and direct observation, recorded G. basitruncatum in the new segments of the gallery and on male exoskeleton. Additionally, species of Graphium have been reported as insect-vectored (Cruywagen et al 2010), associated with Scolytodes unipunctatus (Hulcr et al 2007;Kolařík et al 2015) and Platypus cylindrus` mycangia (Bellahirech et al 2014), supporting the hypothesis that this fungal genus could be relevant in the interactions.…”

Highlights• There were no significant effects of host plant and location on fungal richness.• Two fungal species, belonging to Fusarium and Candida genera, were present in all the studied associations.• Results suggest that host plant identity would not be crucial to determine the composition of fungal communities associated to Megaplatypus mutatus. AbstractMegaplatypus mutatus is a major forest pest in Argentina and an emerging pest in Europe. In this study the multitrophic interactions between M. mutatus and associated fungi were assessed with a metagenomics approach (454-pyrosequencing). A total of 270 collection points from insect galleries from three locations in Argentina were pooled for pyrosequencing analyses. Two hosts, Populus deltoides and Casuarina cunninghamiana, were independently evaluated to characterize the fungal communities associated to M. mutatus; compare the culture-independent approach with previous culturing studies, in terms of data recovery related to the fungal community composition, and test the specificity of the fungal communities amongst locations and hosts. A Generalized Linear Mixed Model was performed to compare the fungal richness in each dataset, which showed no significant differences between taxa richness amongst locations. Principal Coordinates Analyses showed a separation between fungal communities within the same host, suggesting that host identity would not be crucial to determine the specificity in fungal communities. Candida insectalens and one Fusarium species, present in all hosts and locations, achieved 37.6% of the total relative frequency per taxa. These results complement the data from culturing methods previously reported, thus improving the accuracy and understanding of the fungal assemblages associated to M. mutatus.

“…The two species G. pseudormiticum and G. laricis described by Jacobs et al (2003) differed only by a single ITS nucleotide, which was similar to the G. laricis intra-species variation. Recently Cruywagen et al (2010) distinguished the two species with TEF1 sequences.…”

Abstract:The genus Scedosporium and its relatives comprising microascalean anamorphs with slimy conidia were studied. Graphium and Parascedosporium also belong to this complex, while teleomorphs are found in Pseudallescheria, Petriella, Petriellopsis, and Lophotrichus. Species complexes were clearly resolved by rDNA ITS sequencing. Significantly different ecological trends were observed between resolved species aggregates. The Pseudallescheria and Scedosporium prolificans clades were the only lineages with a marked opportunistic potential to mammals, while Petriella species were associated primarily with soil enriched by, e.g. dung. A consistent association with bark beetles was observed in the Graphium clade. The ex-type strain of Rhinocladium lesnei, CBS 108.10 was incorrectly implicated by Vuillemin (1910) in a case of human mycetoma; its sequence was identical to that of the ex-type strain of Parascedosporium tectonae, CBS 127.84.
