Abstract

During an inventory of ascomycetes in the semi-arid region of Brazil, an undescribed specimen of Bertiella was found. It is described and illustrated as B. gelatinosa sp. nov., based on morphological data. The new fungus is distinguished by the size of the ascospores, which are surrounded by a gelatinous sheath. A synoptic table and a key to all known species of Bertiella are presented.

Abstract

The taxonomy of the family Cucurbitariaceae and its allies, especially Fenestellaceae has received little attention despite its broad relevance. To further clarify phylogenetic relationships between the two families, new collections were made and samples examined morphologically. Morphometric observations reveal two new Fenestella species that are different from other known species and are introduced as Fenestella ostryae sp. nov. and F. mackenziei sp. nov. The asexual morph of F. ostryae is also established from single spore cultures and described. Phylogeny inferred from a combined dataset of ITS, LSU and SSU rDNA sequence also reveals a close association of the new taxa to F. fenestrata, but they are distinct. Sequence analyses also support our previous assumption that Fenestellaceae should be synonymized with Cucurbitariaceae. Pyrenochaeta quercina, Pyrenochaeta unguis-hominis and an additional new cucurbitaria-like isolate constitute a strongly supported monophyletic lineage within Cucurbitariaceae. To better resolve intergeneric level relationships and improve taxonomic issues within Cucurbitariaceae, a new genus, Neocucurbitaria gen. nov. is introduced with Neocucurbitaria acerina as a new species.

Abstract

A new species of Magnicamarosporium, M. diospyricola was found on dead or dying twigs of a dicotyledonous plant in southern Thailand. The new species is distinct from other species in Sulcatisporaceae, as it has dematiaceous dictyosporous conidia. It differs from Magnicamarosporium iriomotense in its smaller conidiomata and conidia. Bayesian inference and maximum likelihood analysis of combined LSU, SSU, ITS, and TEF1-α sequence data indicate that M. diospyricola is a well-resolved species, sister to M. iriomotense, in the family Sulcatisporaceae. The morphology and phylogenetic placement of the new species are discussed in this paper.
