This is the third paper in the series, Mycosphere notes, wherein we provide notes on various fungal taxa. In this set of notes, we deal with species found on the grape genus, Vitis, one of the most important economically important crops, grown worldwide. We provide notes on 67 taxa, including two new species, Alternaria italica and Alfaria vitis, an asexual morph for Alfaria cyperi-esculenti and 41 new host records or distribution records. The taxonomic placement of most taxa discussed in this study is based on a modern taxonomic framework based on analysis of multi-gene sequence data.

Keywords: 2 new species – Alfaria vitis – Alternaria italica – Grapevine – Molecular phylogeny – New host records – Saprotrophs

2. Notes for genera update – Ascomycota: 6616-6821

Taxonomic knowledge of the Ascomycota, is rapidly changing because of use of molecular data, thus continuous updates of existing taxonomic data with new data is essential. In the current paper, we compile existing data of several genera missing from the recently published “Notes for genera-Ascomycota”. This includes 206 entries.

3. Cantharellus subg. Pseudocantharellus (Hydnaceae, Cantharellales) revisited: one epityfication, one new synonym and one new species

Authors: Buyck B, Hofstetter V

Cantharellus rhodophyllus is epitypified with a recent collection from the African rain forest and full barcode ITS sequences are provided. After a detailed comparison of the original descriptions and these new collections, C. subincarnatus – introduced as a new name for the invalid C. incarnatus – is considered a later synonym. Phylogenetic analysis using tef-1 sequence data place C. rhodophyllus in Cantharellus subg. Pseudocantharellus and demonstrate that C. subincarnatus subsp. rubrosalmoneus from Madagascar is an independent species that is more closely related to C. miniatescens.

Keywords: 1 new species – Barcoding – Cantharellus rhodophyllus – Cantharellus subincarnatus – Cantharellus rubrosalmoneus – ITS – tef-1

The yeasts were observed attached to the mouthparts, wings, and forelegs of migratory butterflies in Taiwan. Fifty-eight dominant yeast strains yeasts were isolated from 56 Euploea butterflies and identified by rDNA ITS and D1/D2 sequencing. The yeasts which associated with Euploea butterflies included ascomycetous yeasts, such as Aureobasidium sp., Candida chanthaburiensis, C. corydalis, Metschnikowia koreensis, Metschnikowia sp., and Debaryomyces hansenii; and basidiomycetous yeasts, such as Cryptococcus rajasthanensis, Dirkmeia churashimaensis, Filobasidium globisporum, Hannaella pagnoccae, Papiliotrema flavescens, Pseudozyma hubeiensis, P. tsukubaensis, Pseudozyma sp., Rhodotorula mucilaginosa, R. subericola, and Rhodosporidiobolus poonsookiae. The most common yeast, Candida corydalis, associated with 4 migratory Euploea species and seemed transmitted through nectar. When the butterflies feed on nectar, bask in the sun on the leaf, sip at the moisture on leaves, in puddles or wet sand and soil, they come into contact with yeasts. This is the first report about the yeast microbiome of migratory butterflies.

5. Orbiliaceae from Thailand

Authors: Ekanayaka AH, Hyde KD, Jones EBG, Zhao Q

Recieved: 06 December 2017, Accepted: 22 January 2018, Published: 27 February 2018

The family Orbiliaceae is characterized by small, yellowish, sessile to sub-stipitate apothecia, inoperculate asci and asymmetrical globose to fusoid ascospores. Morphological and phylogenetic studies were carried out on new collections of Orbiliaceae from Thailand and revealed Hyalorbilia erythrostigma, Hyalorbilia inflatula, Orbilia stipitata sp. nov., Orbilia leucostigma and Orbilia caudata. Our new species is confirmed to be divergent from other Orbiliaceae species based on morphological examination and molecular phylogenetic analyses of ITS and LSU sequence data. Descriptions and figures are provided for the taxa which are also compared with allied taxa.
