Antrodia uzbekistanica sp. nov. is described and illustrated from juniper trees in Uzbekistan based on morphological characters and molecular evidence. It is characterized by producing annual, resupinate basidiome with large pores (1–2 per mm), a dimitic hyphal structure with clamp connections on generative hyphae, hyaline, thin-walled and cylindric basidiospores (6.5–8 × 2.7–3 µm), the presence of thick-walled and cyanophilous chlamydospores, and by causing a typical brown rot of Juniperus seravschanica in arid and semi-arid regions of Uzbekistan. The new species resembles Antrodia sinuosa macroscopically, but this species differs by having smaller basidiospores (4–6 × 1–2 µm), lacking of chlamydospores, and growing on wood of Pinaceae species. In nuclear large subunit rDNA (nLSU) and internal transcribed spacer (ITS) based phylogenies, the new species formed a distinct lineage in the Antrodia clade, and it is closely related to A. juniperina, which differs by having perennial, effused-reflexed basidiome with nodulose or round edged pilei, daedaleoid to labyrinthine pores, and larger and narrowly ellipsoid basidiospores (6.5–9 × 2.5–3.5 µm).

A New Species

Abstract M. fructigena is one of several apothecial ascomycetes causing brown rot and blossom blight of stone fruit and pome fruit trees worldwide. It has a more restricted distribution than the other species, occurring in Europe and Asia, but not in North America. Reports of its occurrence in South America are likely to be errors in identification. Recent identification of a new species in Japan suggests that it may not be present there, as previously thought, and reports from other parts of eastern Asia may have to be re-examined. It is a quarantine pest for Canada, the USA, Australia and New Zealand. One unusual introduction to the USA was resolved by eradication (Batra, 1979; Ogawa and English, 1991). Introduction could occur through the importation of infected fruit as well as of tree material for propagation and breeding, from which it could spread readily by means of conidia carried by the wind or insects.

A New Species

Gall midges have been reported from cones of western red cedar, Thuja plicata Donn., but none have been described. Keen (1958) reported the occurrence in Washington and Oregon of a cone midge which was credited with destroying 90 per cent of the seed. In 1940 Prebble and Graham reported a midge in cones of western red cedar at Cowichan Lake, B.C. These reports almost certainly refer to the midge described here. The only other species taken from red cedar cones was Lestodiplosis taxiconis Foote, but it occurred in verysmall numbers; previously it has been reported only from cones of Douglas fir, Pseudotsuga menziesii (Mirb.) Franco (Foote, 1956).

A New Species

A new species of Diaporthe, for which the name D. lokoyae Funk is proposed, is described on the host Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and in culture. This Diaporthe is shown to be the ascigerous state of Phomopsis lokoyae Hahn. An outbreak of dieback in Douglas fir associated with this Diaporthe is described and discussed; a single occurrence on western hemlock (Tsuga heterophylla (Raf.) Sarg.) is reported.

A New Species

Brown rot caused by Monilinia spp. is one of the most important diseases of stone fruits. To date, three species of Monilinia have been found to occur on Prunus species worldwide: Monilinia fructicola (G. Winter) Honey, Monilinia fructigena (Aderhold & Ruhland) Honey, and Monilinia laxa (Aderhold & Ruhland) Honey (Zhu et al. 2005; Hu et al. 2011a). While M. fructicola is widespread in the Americas, and parts of Europe and Asia (CABI, 2010), M. laxa and M. fructigena are the primary species causing brown rot of peach in Europe (Bryde et al. 1977). In China, a new species Monilia yunnanensis was identified in 2011 (Hu et al. 2011b; Zhao et al. 2013; Yin et al. 2015; Yin et al. 2017). However, the species causing brown rot of nectarine (Prunus persica var. nectarina) in Tibet have not been undertaken. In the summer of 2017-2018, brown rot disease of nectarine was observed in Nyingchi, Tibet, and approximately 30% of nectarines were affected annually. Therefore, the brown rot disease of nectarine is one of the main factors that restrict the yield and quality of nectarine fruit production, and causes severe economic losses in Tibet. Thirty-six nectarine fruit with typical brown rot symptoms were collected from Tibet during the summer of 2017-2018. In order to isolate the causal agent, small pieces of pericarp were disinfected with 75% ethanol for 1 min, and then for 1 min in 1% NaOCl, rinsed in sterile distilled water for three times, dried on sterile paper and placed on potato dextrose agar (PDA). Thirty-six single-spore isolates were obtained and all morphologically similar, and three representative isolates 2-1, 2-16 and 2-31 which were from different period and years in 2017-2018 were characterized phylogenetically and morphologically to identify them to species level. Pathogenicity of each representative isolate was confirmed by inoculating five surface-disinfected mature nectarines with mycelial plugs in the wound of the fruit. Nectarine fruit inoculated with sterile PDA plugs served as the negative control. The inoculated nectarines developed brown lesions after 6 days incubation at 22°C, and the pathogen was successfully re-isolated. There were no symptoms on the control nectarine fruit. The isolates 2-1, 2-16 and 2-31 produced gray-green colonies with even margins and concentric rings of sporogenous mycelium after 3 days incubation, and abundant black-colored stromata on the media after 16 days of incubation at 22°C, resembling those described for M. yunnanensis (Hu et al. 2011b). Conidia were one-celled, hyaline, ellipsoid to lemon shape (9.24 to 15.58 μm), and borne in branched monilioid chains. The average daily growth of mycelium on PDA at 22°C was 11.56 mm. Therefore, the isolates 2-1, 2-16 and 2-31 were preliminarily identified as M. yunnanensis based on the morphological investigations (Hu et al. 2011b). Morphological identification was confirmed by phylogenetic analysis based on sequences of glyceraldehyde-3-phosphate dehydrogenase (G3PDH) and β-tubulin (TUB2) genes of 2-1, 2-16 and 2-31 which were amplified using primers Mon-G3pdhF/Mon-G3pdhR and Mon-TubF1/Mon-TubR1 (Hu et al. 2011b). In both G3PDH and TUB2 phylogenetic trees, the isolates 2-1, 2-16 and 2-31 formed monophyletic clades within a derived clade with the M. yunnanensis isolates. Additionally, the three isolates were more closely related to M. yunnanensis (HQ908782.1 and HQ908783.1) than to other Monilinia species. Based on morphological and molecular identification, the isolates 2-1, 2-16 and 2-31 were identified as M. yunnanensis. Previously, M. yunnanensis has been reported as a new species causing brown rot of peach in China (Hu et al, 2011b). To our knowledge, this is the first report of M. yunnanensis causing nectarine fruit brown rot in Tibet. These findings suggest that M. yunnanensis is spreading on its principal host plants and causing substantial economic losses in the Tibet fruit production.

A New Species

A new species of Leucogyrophana (Boletales: Coniophoraceae) is described. Leucogyrophana lichenicola is compared with Leucogyrophana romellii Ginns, from which it differs in being lichenicolous, producing brightly colored sclerotia, and in certain cultural characters. The new species produces both basidiomata and orange sclerotia within and on the undersides of lichen mats of the genera Cladonia and Stereocaulon. It has been recorded from Ontario, Quebec, and the Northwest Territories in Canada and from Finland, Norway, and Sweden. The geographic and host ranges for L. romellii are extended. The cultures of L. lichenicola and L. romellii showed no activity for laccase, tyrosinase, peroxidase, or ligninase, but cellulase activity was present.Key words: lichenicolous fungi, brown-rot fungi, Basidiomycota, Boletales.
