Causing Leaf Spot Disease in Key Tropical Fruit Crops in Thailand.

Fruit crops have a pivotal role in Thailand's economy. Continuous evaluation of 13 potential and emerging diseases in fruit crops is important. Necrotic and discolored leaf spots were observed in (avocado) and (mango).

Identification and Pathogenicity of Species Associated with Leaf Spot Disease in Northern Thailand.

Species of that are reported as plant pathogens and cause leaf spot or leaf blight have been reported on many commercial crops worldwide. In 2019, during a survey of fungi causing leaf spots on plants in Chiang Mai and Mae Hong Son provinces, northern Thailand, 16 isolates from 14 host species across nine plant families were collected. A new species sp.

Morpho-molecular characterisation of , with and sp. nov. and comb. nov.

Three arecophila-like fungal samples were collected on dead culms of gramineous plants in China. Morphological studies of our new collections and the herbarium specimen of (generic type) were conducted and the morphological affinity of our new collections with was confirmed. Maximum likelihood and Bayesian analyses using combined ITS, LSU, 2 and β-tubulin data from our collections revealed the phylogeny of .

Fungal Pathogens in Grasslands.

Grasslands are major primary producers and function as major components of important watersheds. Although a concise definition of grasslands cannot be given using a physiognomic or structural approach, grasslands can be described as vegetation communities experiencing periodical droughts and with canopies dominated by grasses and grass-like plants. Grasslands have a cosmopolitan distribution except for the Antarctic region.

Patellariopsidaceae Fam. Nov. With Sexual-Asexual Connection and a New Host Record for (Vibrisseaceae, Ascomycota).

Helotiales is a polyphyletic order of Ascomycetes. The paucity of relevant molecular data and unclear connections of sexual and asexual morphs present challenges in resolving taxa within this order. In the present study, Patellariopsidaceae fam.
