New Host Records

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.

Thirty-four Lycoperdon specimens from Korea were examined with the internal transcribed spacer (ITS) region of ribosomal DNA sequence data. The result of the ITS sequences phylogenetic analysis indicated that the Korean specimens represented nine different species. To confirm the taxonomic position of these species, we conducted an intensive morphological investigation, and additional phylogenetic investigation of the protein coding regions RNA polymerase subunit II (RPB2) and translation elongation factor 1-alpha (TEF1). We discovered two new species (L. albiperidium and L. subperlatum) and one (L. ericaeum) newly discovered in Korea. Lycoperdon albiperidium is closely related to L. ericaeum based on ITS, RPB2 and TEF1 sequence data, but these species were distinguishable by morphological characteristics, especially the shape of the basidiocarps, the diameter of the eucapillitial threads and the size of the basidospores. Lycoperdon subperlatum is quite similar to the European and American L. perlatum based on morphological characteristics. However, L. subperlatum is clearly distinct from European and American L. perlatum based on ITS, RPB2 and TEF1 sequence data, and somewhat differs from them in macro- and microscopic characteristics. Based on morphological characteristics, L. ericaeum is related to L. subumbrinum and L. lividum but it is distinguishable by the presence of fragile, eucapillitial threads, the diameters of the threads and ITS sequences. Here, we describe four Lycoperdon species collected in Korea.

The Botryosphaeriales is a cosmopolitan fungal order and genera belonging to it are common opportunistic pathogens which mostly infect woody plants. They cause fruit rot, dieback, trunk rot, canker and similar diseases killing trees of natural forests, plantations and fruit trees. Relatively recently, some new families (including family Aplosporellaceae) had been established within this order delineating from family Botryosphaeriaceae. In the present study, two strains (MMI00067 and MMI00068) were isolated from soil attached to the base of a macrofungal stipe collected from the forest of Anuppur (Amarkantak), Madhya Pradesh, India. Strains were identified by DNA sequence data of four loci viz., internal transcribed spacer (ITS) of rDNA, large subunit rDNA (LSU), translation elongation factor (tef) and partial β-tubulin (βtub). Based on the phylogenetic analysis, a new fungal genus Alanomyces is proposed and is positioned within Aplosporellaceae along with Aplosporella. It is characterized by fast growing, dark greenish-black colony, long neck-like multilocular-papillate, black pycnidia with separate ostiole and small <10 µm in length, cylindrical, hyaline, guttulate spermatia. The genus Alanomyces is phylogenetically distinct from its close relative Aplosporella and proposed herein as a new monotypic genus with A. indica as type species.

The grass Ammophila breviligulata (American beachgrass) is known to host an endophyte of the genus Epichloë. Based on morphological characteristics it was originally identified as Acremonium typhinum var. ammophilae and is currently designated as Epichloë typhina var. ammophilae. However, the Epichloë species has not previously been identified based on DNA sequence data. Based on phylogenetic placement of beta-tubulin and translation elongation factor 1-alpha DNA sequences the endophyte is identified as a member of E. amarillans rather than E. typhina.

Agaricus is a saprophytic mushroom genus widely distributed throughout the world. In this study, a survey of the Agaricus species carried out around Chiang Mai University in northern Thailand from 2018 to 2019 yielded 12 collections. Morphological characteristics and phylogenic analyses based on the internal transcribed spacers (ITS) and a fragment of the large subunit (LSU) of the nuclear ribosomal DNA (rDNA), and a fragment of the translation elongation factor 1-alpha (tef1) genes were investigated. The results revealed that these collections belong to six species including Agaricus erectosquamosus, Agaricus pallidobrunneus, Agaricus subrufescens, and three new species. Agaricus thailandensis sp. nov. was found to belong to Agaricus sect. Minores, which is placed in Agaricus subg. Minores. Aagricus pseudoerectosquamosus sp. nov. was placed in Agaricus sect. Brunneopicti within Agaricus subg. Pseudochitonia. Furthermore, Agaricus lannaensis remains an incertae sedis in Agaricus subg. Pseudochitonia. Additionally, this study was proposed that A. pallidobrunneus was discovered in Thailand for the first time. Full descriptions, color photographs, illustrations, and phylogenetic trees are provided.

Neofusicoccum species are endophytes, saprobes and opportunistic pathogens of many economic and ornamental plants. There are few reports of Neofusicoccum species are available to be associated with orchids worldwide. In this study, five endophytic Neofusicoccum strains were isolated from Dendrobium orchid leaves and stems in southwestern China and northern Thailand. Morphological characteristics and phylogenetic analysis of the combined partial nuclear rDNA internal transcribed spacer (ITS), partial RNA polymerase Ⅱ second largest subunit (RPB2), part of the translation elongation factor 1 alpha (EF-1α) and beta-tubulin (TUB2) dataset revealed that these isolates belong to two species Neofusicoccum occulatum and N. parvum. This is the first record of Neofusicoccum occulatum associated with Dendrobium chrysanthum while N. parvum associated with D. harveyanum and D. moschatum.

Persian lime (Citrus latifolia Tan.) is an important and widely cultivated fruit crop in several regions of Mexico. In recent years, severe symptoms of gummosis, stem cankers, and dieback were detected in the Persian lime-producing region in the states of Veracruz and Puebla, Mexico. The aims of this study were to identify the species of Lasiodiplodia associated with these symptoms, determine the distribution of these species, and test their pathogenicity and virulence on Persian lime plants. In 2015, symptomatic samples were collected from 12 commercial Persian lime orchards, and 60 Lasiodiplodia isolates were obtained. Fungal identification of 32 representative isolates was performed using a phylogenetic analysis based on DNA sequence data of the internal transcribed spacer region and part of the translation elongation factor 1-α and β-tubulin genes. Sequence analyses were carried out using the Maximum Likelihood and Bayesian Inference methods. Six Lasiodiplodia species were identified as Lasiodiplodia pseudotheobromae, Lasiodiplodia theobromae, Lasiodiplodia brasiliense, Lasiodiplodia subglobosa, Lasiodiplodia citricola, and Lasiodiplodia iraniensis. All Lasiodiplodia species of this study are reported for the first time in association with Persian lime in Mexico and worldwide. L. pseudotheobromae (46.9% of isolates) was the most frequently isolated species followed by L. theobromae (28.1%) and L. brasiliense (12.5%). Pathogenicity on Persian lime young plants using a mycelial plug inoculation method showed that all identified Lasiodiplodia species were able to cause necrotic lesions and gummosis, but L. subglobosa, L. iraniensis, and L. pseudotheobromae were the most virulent.

Botryosphaeriales is an important order of diverse fungal pathogens, saprobes, and endophytes distributed worldwide. Recent studies of Botryosphaeriales in China have discovered a broad range of species, some of which have not been formerly described. In this study, 60 saprobic isolates were obtained from decaying woody hosts in southwestern China. The isolates were compared with other species using morphological characteristics, and available DNA sequence data was used to infer phylogenetic analyses based on the internal transcribed spacer (ITS), large subunit rRNA gene (LSU), and translation elongation factor 1-α (tef) loci. Three novel species were illustrated and described as Botryobambusa guizhouensis, Sardiniella elliptica, and Sphaeropsis guizhouensis, which belong to rarely identified genera within Botryosphaeriaceae. Botryobambusa guizhouensis is the second species identified from the respective monotypic genus. The previously known species were identified as Aplosporella hesperidica, Barriopsis tectonae, Botryosphaeria dothidea, Diplodia mutila, Di. neojuniperi, Di. pseudoseriata, Di. sapinea, Di. seriata, Dothiorella sarmentorum, Do. yunnana, Lasiodiplodia pseudotheobromae, Neofusicoccum parvum, Sardiniella celtidis, Sa. guizhouensis, and Sphaeropsis citrigena. The results of this study indicate that numerous species of Botryosphaeriales are yet to be revealed in southwestern China.

Three New Species

The taxonomy of Oculimacula, Rhynchosporium and Spermospora is re-evaluated, along with that of phylogenetically related genera. Isolates are identified using comparisons of DNA sequences of the internal transcribed spacer ribosomal RNA locus (ITS), partial translation elongation factor 1-alpha (tef1), actin (act), DNA-directed RNA polymerase II largest (rpb1) and second largest subunit (rpb2) genes, and the nuclear ribosomal large subunit (LSU), combined with their morphological characteristics. Oculimacula is restricted to two species, O. acuformis and O. yallundae, with O. aestiva placed in Cyphellophora, and O. anguioides accommodated in a new genus, Helgardiomyces. Rhynchosporium s. str. is restricted to species with 1-septate conidia and hooked apical beaks, while Rhynchobrunnera is introduced for species with 1–3-septate, straight conidia, lacking any apical beak. Rhynchosporium graminicola is proposed to replace the name R. commune applied to the barley scald pathogen based on nomenclatural priority. Spermospora is shown to be paraphyletic, representing Spermospora (type: S. subulata), with three new species, S. arrhenatheri, S. loliiphila and S. zeae, and Neospermospora gen. nov. (type: N. avenae). Ypsilina (type: Y. graminea), is shown to be monophyletic, but appears to be of minor importance on cereals. Finally, Vanderaaea gen. nov. (type: V. ammophilae), is introduced as a new coelomycetous fungus occurring on dead leaves of Ammophila arenaria.

Citrus Trees

Citrus trees with cankers and dieback symptoms were observed in Bushehr (Bushehr province, Iran). Isolations were made from diseased cankers and branches. Recovered fungal isolates were identified using cultural and morphological characteristics, as well as comparisons of DNA sequence data of the nuclear ribosomal DNA-internal transcribed spacer region, translation elongation factor 1α, β-tubulin, and actin gene regions. Dothiorella viticola, Lasiodiplodia theobromae, Neoscytalidium hyalinum, Phaeoacremonium (P.) parasiticum, P. italicum, P. iranianum, P. rubrigenum, P. minimum, P. croatiense, P. fraxinopensylvanicum, Phaeoacremonium sp., Cadophora luteo-olivacea, Biscogniauxia (B.) mediterranea, Colletotrichum gloeosporioides, C. boninense, Peyronellaea (Pa.) pinodella, Stilbocrea (S.) walteri, and several isolates of Phoma, Pestalotiopsis, and Fusarium species were obtained from diseased trees. The pathogenicity tests were conducted by artificial inoculation of excised shoots of healthy acid lime trees (Citrus aurantifolia) under controlled conditions. Lasiodiplodia theobromae was the most virulent and caused the longest lesions within 40 days of inoculation. According to literature reviews, this is the first report of L. theobromae and N. hyalinum on citrus in Iran. Additionally, we report several Phaeoacremonium species, S. walteri, Pa. pinodella and C. luteo-olivacea on citrus trees for the first time in the world.
