Taxonomic and phylogenetic analysis of Clinoconidium lauracearum (Cryptobasidiaceae) producing galls on fruits of Cinnamomum tamala (Lauraceae) in India

(Cryptobasidiaceae) is described and illustrated from infected fruits of Cinnamomum tamala (Lauraceae) collected from Rudraprayag district of Uttarakhand State, India. The species shows characteristics of Clinoconidium and Drepanoconis, but differs from other species in these genera by the combination of shapes, sizes, and septation of basidiospores. Molecular data also indicate that the present taxon is distinct from the other known species of Clinoconidium and Drepanoconis. Analyses of combined ITS and LSU rDNA and separate LSU rDNA sequence data reveal a close association of the present taxon to the genus Clinoconidium, but also that it is distinct from the other known species in the genus.

Morphologically, this species has characters similar to allied species in the genus Ochroconis, but differs in conidial dimensions and shape. Phylogenetic analyses using nuclear ribosomal DNA gene ITS and protein coding gene BT2 revealed it clustering as monophyletic clade which was separated from known Ochroconis species. New species was isolated from leaf surface of medicinal plant Helicteris isora L.
Strelitziana sarbhoyi sp. nov. (Strelitzianaceae, Chaetothyriales), from North-Western Himalayas, India, described based on morphology and molecular phylogeny

The identity of the fungus is confirmed based on the asexual-morphs, cultural characteristics and phylogenetic analyses of the internal transcribed spacer (ITS) rDNA and partial nuclear ribosomal 28S large subunit (LSU) sequence data. The placement of S. sarbhoyi in the phylogenetic tree was determined based on DNA sequences from authenticated isolates of Strelitziana. Strelitziana sarbhoyi shows nearly 94% similarity with other known species of Strelitziana. Area description is provided for the proposed taxon along with microscopic images, and a phylogenetic tree. This is probably the first report of Strelitziana from India. Holotype specimen (dried voucher culture) is deposited in the Ajrekar Mycological Herbarium (AMH), and an ex-type culture is deposited in National Fungal Culture ...

Both treated hyphomycetous taxa were collected in the forests of Western Ghats, India.

A wide geographic and taxonomic range of fungal taxa are detailed. In the Ascomycota the new genera Angustospora (Testudinaceae), Camporesia (Xylariaceae), Clematidis, Crassiparies (Pleosporales genera incertae sedis), Farasanispora, Longiostiolum (Pleosporales genera incertae sedis), Multilocularia (Parabambusicolaceae), Neophaeocryptopus (Dothideaceae), Parameliola (Pleosporales genera incertae sedis), and Towyspora (Lentitheciaceae) are introduced. Newly introduced species are Angustospora nilensis, Aniptodera

High-performance liquid chromatography analysis confirmed the presence of carotenoid pigment. Gas chromatography observations showed the presence of major fatty acids: myristic acid (14:0), palmitic acid (16:0), stearic acid (18:0), heptadecanoic acid (17:0), linolenic acid (18:3) and linoleic acid (18:2). Of these, linolenic acid, a polyunsaturated fatty acid, was present in substantial quantity, suggesting that it may have a role in adapting the fungus to low Antarctic temperatures by modulating membrane fluidity. The commercial application of linolenic acid is as a food supplement for humans suffering from eczema, cardiovascular disease and diabetic neuropathy. Another fatty acid, linoleic acid, a precursor of 1-octen-3-ol, is the principal aromatic compound in most fungi and has also been documented in this strain. Screening of the fungal cult...

The new species, distinguished by morphological and in vitro cultural characters, forms dark brown lenticular conidia with hyaline equatorial germ slits together with balloon-shaped, anomalous conidia uncommon in the morphologically similar A. phaeospermum. Additionally, internal transcribed spacer (ITS) rDNA sequence analyses support this species as distinct within Arthrinium. Isolates previously identified as A. phaeospermum from China and Japan are re-determined as A. rasikravindrii.
