Phylloporia species are, however, morphologically and ecologically diverse, which makes morphology-based species identification challenging. In this study, we re-examined species of Phylloporia reported from Benin (West Africa). Read More

Four mycelial strains of Entoloma clypeatum species complex form ectomycorrhiza-like roots with Pyrus betulifolia seedlings in vitro, and one develops fruiting bodies 2 months after inoculation.

Mycorrhiza 2021 Jan 26;31(1):31-42. Epub 2020 Oct 26.

Fungus/Mushroom Resource and Research Center, Faculty of Agriculture, Tottori University, 4-101 Koyama, Tottori, 680-8553, Japan.

Entoloma clypeatum species complex (ECSC) forms ectomycorrhiza-like roots (EMLR) with host plant species of Rosaceae or Ulmaceae. The EMLR colonized with ECSC are characterized by a thick fungal mantle, absence of a Hartig net structure, and collapse of the apical meristem caused by hyphal invasion. Some researchers have suggested parasitism of ECSC because of this unique mode of colonization; however, the nature of the interaction between ECSC and host plants has not been investigated in co-culture because of the difficulty of culturing this group of fungi.

Patterns of allele distribution in a hybrid population of the Cryptococcus neoformans species complex.

Mycoses 2020 Mar 9;63(3):275-283. Epub 2019 Dec 9.

Department of Biology, McMaster University, Hamilton, ON, Canada.

Background: The sister yeast species Cryptococcus neoformans (serotype A) and Cryptococcus deneoformans (serotype D) are causative agents of deadly cryptococcosis and fungal meningoencephalitis. These haploid yeasts can hybridise in nature, giving rise to AD hybrids that are predominantly diploid or aneuploid. Despite their increasing prevalence in clinical settings, much remains unknown about the allelic distribution patterns in AD hybrid strains. Read More

The basidiospores of most Agaricomycetes are ballistospores. They are propelled off from their basidia at maturity when Buller's drop develops at high humidity at the hilar spore appendix and fuses with a liquid film formed on the adaxial side of the spore. Spores are catapulted into the free air space between hymenia and fall then out of the mushroom's cap by gravity. Read More

Bermudagrass (Cynodon dactylon) is an important warm-season perennial turf and forage grass that is typically grown in warm, tropical and subtropical climates. Smutted inflorescences of bermudagrass were observed and collected in Benton County, Washington, United States, in October of 2012 in an unmanaged, naturalized area located near the banks of the Columbia River and adjacent to large expanses of managed turf containing bermudagrass. The climate in this area is favorable to bermudagrass due to the relatively mild winters and hot, dry summers that usually occur in this region. Read More

Evidence for mitotic recombination within the basidia of a hybrid cross of Cryptococcus neoformans.

PLoS One 2013 14;8(5):e62790. Epub 2013 May 14.

Department of Biology, McMaster University, Hamilton, Ontario, Canada.

In the majority of diploid eukaryotes, each meiotic process generates four haploid gametes with each containing a single recombinant nucleus. In some species and/or some meiotic processes, aneuploid or diploid gametes can also be generated due to chromosomal non-disjunction and/or the co-packaging of two of the four haploid nuclei into the same gamete. Here we show that another process is involved in generating genotypes of sexual progeny from a hybrid cross between two divergent lineages of the human fungal pathogen Cryptococcus neoformans.
