New Host Records

A novel taxon, Pseudorobillarda camelliae-sinensis (Pseudorobillardaceae) and new host records of pleosporalean taxa viz. Neopyrenochaeta triseptatispora (Neopyrenochaetaceae), Ramusculicola thailandica (Teichosporaceae) and Vaginatispora palmae (Lophiostomataceae) resulted from our investigation of plant-associated microfungi in Alishan and Fenghuang Mountain ranges in Taiwan. These taxa were isolated from dicotyledonous hosts of Bignoniaceae, Caprifoliaceae, Meliaceae and Moraceae. Maximum likelihood and Bayesian inference analyses were performed using combined SSU, LSU, ITS, tef1-α and rpb2 sequence data to clarify the phylogenetic affinities of taxa. The newly described taxa of the current study are accompanied by comprehensive descriptions, micrographs and comparisons with similar species. In addition, the importance of exploiting fungi from mountain habitats in Taiwan is discussed.

A New Species

Phaeosphaeria ampeli is a new species collected from dead leaves of Ficus ampelas in Fanlu Township area, Dahu forest, Chiayi, Taiwan. Phaeosphaeria musae is a new record from dead leaves of Roystonea regia. Both species are described, illustrated and compared with similar species. Phaeosphaeria ampeli is distinguished from other Phaeosphaeria species based on distinct size differences of the ascomata, asci, ascospores and analyses of DNA sequence data. Maximum parsimony, maximum likelihood and Bayesian inference analyses of combined ITS, LSU, SSU and tef1-α sequence data are used to clarify the phylogenetic affinities of the species.

The genus Lamproconium comprises species that are endophytes, saprobes and pathogens on a wide variety of plants. This genus is currently placed in Diaporthales genera incertae sedis. Fresh specimens of Lamproconium were collected in Russia and studied to provide morphological and phylogenetic data. Phylogenetic analyses of single spore isolates generated from maximum likelihood, maximum parsimony and Bayesian inference analyses using combined ITS and LSU sequence data, place L. desmazieri in the order Diaporthales. Melanconis desmazieri is synonymized under Lamproconium desmazieri, and Lamproconiaceae is introduced as a new family to accommodate L. desmazieri and Hercospora tiliae, based on morphology and phylogenetic analyses.

The Chinese species of Pediobius Walker, 1846 are treated in this paper, resulting in 34 species, of which 5 are newly described: P. bisulcatus Cao & Zhu sp. n., P. elongatus Cao & Zhu sp. n., P.petiolapilus Cao & Zhu sp. n., P. prominentis Cao & Zhu, sp. n., and P. tortricida Cao & Zhu, sp. n. Nine species are also newly recorded from China: P. anomalus (Gahan, 1920), P. bethylicidus Kerrich, 1973, P. bruchicida (Rondani, 1872), P. cassidae Erdös, 1958, P. claviger (Thomson, 1878), P. erionotae Kerrich, 1973, P. phragmitis Bouček, 1965, P. saulius (Walker, 1839), and P. tetratomus (Thomson, 1878). Four new synonyms are proposed: P. illiberidis Liao, 1987 under P. pyrgo (Walker, 1839) syn. n., P. planiceps Sheng & Kamijo, 1992 under P. inexpectatus Kerrich, 1973 syn. n., P. sinensis Sheng & Wang, 1994 under P. facialis (Giraud, 1863) syn. n., and P. songshaominus Liao, 1987 under P. yunanensis Liao, 1987 syn. n. The species-group concept is used to compare similar species, of which eight are recognized in China including two newly recognized groups: the cassidae-group and the crassicornis-group. One species complex, the P. eubius complex, is also recognized. An updated checklist of the Chinese species of Pediobius is provided, with species-group placement. New host records for Pediobius species from China are summarized in a table and valid species possibly present in China but not included in this study in another table. A key to all known females and males of Chinese Pediobius is also provided.

The genus Apiospora is known as a cosmopolitan genus, found across various substrates. In this study, four Apiospora taxa were obtained from the decaying stems of bamboo and maize in northern Thailand. Apiospora collections were compared with known species based on the morphological characteristics and the DNA sequence data of internal transcribed spacer (ITS), the partial large subunit nuclear rDNA (LSU), the translation elongation factor 1-alpha gene (TEF1-α) and beta-tubulins (TUB2). Apiospora chiangraiense sp. nov. and two new host records (Ap. intestini and Ap. rasikravindra) are introduced here based on the morphological characteristics and multi-locus analyses. Additionally, thirteen species previously identified as Arthrinium are introduced as new combinations in Apiospora, viz., Ap. acutiapica, Ap. bambusicola, Ap. biserialis, Ap. cordylines, Ap. cyclobalanopsidis, Ap. euphorbiae, Ap. gelatinosa, Ap. locuta-pollinis, Ap. minutispora, Ap. pseudorasikravindrae, Ap. septate, Ap. setariae and Ap. sorghi.

A new wood-inhabiting species, Neofavolus yunnanensis, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by an annual growth, laterally stipitate basidiomata with reniform to semicircular pileus, dimitic hyphal system with clamped generative hyphae, IKI–, CB–, and cylindrical, hyaline, thin-walled, smooth, IKI–, CB– basidiospores. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses showed that N. yunnanensis was nested into the genus Neofavolus and then was as a sister with N. mikawae and then grouped with N. alveolaris and N. cremeoalbidus.
