“…Additionally, the genera Pythiogeton and Lagena seem to be phylogenetically situated within, or closely related to Pythium emend Uzuhashi, Tojo and Kakishima (Fig. 21, Huang et al 2013a), so even this revised version of Pythium is paraphyletic. For these reasons investigators have generally been slow to adopt the proposed genera.…”

Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi. Molecular (DNA sequence) data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies, although hampered in part by non-standard laboratory practices and analytical methods. To facilitate current and future research, this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, Basidiomycota, Mucormycotina (Fungi), and Oomycota, using recent molecular data, up-to-date names, and the latest taxonomic insights. Lineagespecific laboratory protocols together with advice on their application, as well as general observations, are also provided. We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge. Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort. Bipolaris, Botryosphaeriaceae,

“…With recent sequence analyses of CoxI (cytochrome c oxidase subunit 1) and ITS (internal transcribed spacer) regions of Pythiogeton spp., the genus was revealed to be closely related to Pythium and has consequently remained within the Pythiaceae (De Cock et al, 2010;Huang et al, 2013;Robideau et al, 2011). The genus was distinguished from Pythium by the presence of narrow hyphae, production of zoospores outside asymmetrical sporangia and strictly plerotic oospores with extreme thick oospore walls when present (Huang et al, 2013;Voglmayr et al, 1999). The genus was believed to be recalcitrant for research because of its unculturable and unstorable features (Jee et al, 2000).…”

“…The genus was believed to be recalcitrant for research because of its unculturable and unstorable features (Jee et al, 2000). However, Ann et al (2006) and Huang et al (2013) recently reasoned that as long as suitable media and working approaches were implemented, pure cultures can be obtained. In fact, Py.…”

“…ramosum-like isolates recovered from cypress and English ivy were able to grow normally on oomycete selective medium (PARPH), V8 juice (V8), corn meal agar (CMA), potato dextrose agar (PDA) and carrot agar (CA) media (Silva-Rojas et al, 2004). Huang et al (2013) also found that the genus is in fact very common, but it is usually not recovered during isolation. Hence, once typical narrow glassy and refractive hyphae are recognized, Pythiogeton could be isolated before Pythium or other species overgrow the cultures.…”

“…Approximately 100 years after being described as a new genus, only 15 different species have been ascribed to Pythiogeton including six new species from Taiwan (Huang et al, 2013). Most Pythiogeton spp.…”
