Unveiling Species Diversity of Plectosphaerellaceae (Sordariomycetes) Fungi Involved in Rhizome and Root Rots of Ginger in Shandong Province, China

mycolabadmin

Researchers in China identified four fungal species that cause serious diseases in ginger plants, destroying the underground rhizomes and roots. Two of these species are newly discovered and named after the ginger host and the region where they were found. These fungi are major threats to ginger farming in China’s largest ginger-producing region, causing crop losses ranging from 20-100%.

Four new species of Marasmius subgenus Globulares (Marasmiaceae, Agaricales) from subtropical regions of China

mycolabadmin

Scientists discovered four previously unknown species of small mushrooms called Marasmius in subtropical forests of China. These tiny fungi were identified through detailed examination of their physical characteristics and DNA analysis. The new species have distinctive features like different colored caps, spore sizes, and microscopic structures. This discovery adds to our understanding of fungal biodiversity in Chinese subtropical regions.

Two new species of Neohelicomyces (Tubeufiaceae, Tubeufiales) from Hainan Province, China

mycolabadmin

Researchers discovered two new species of fungi called Neohelicomyces terrestris and Neohelicomyces tropicus in tropical rainforests in China’s Hainan Province. These microscopic fungi were found living on decaying wood and are identified using DNA analysis combined with microscopic examination. The findings expand our knowledge of fungal diversity in tropical environments and these fungi have potential to produce compounds with medical applications.

Damp Buildings: Associated Fungi and How to Find Them

mycolabadmin

This review identifies which fungi commonly grow in damp buildings and explains how to find them. It shows that certain fungi like Penicillium chrysogenum and Aspergillus versicolor grow on different building materials when moisture is present. The guide provides information on proper sampling techniques and identification methods that building inspectors and health professionals need to effectively address moldy building problems.

MycoNews 2023: Editorial, news, reports, awards, personalia, and book news

mycolabadmin

This report highlights major developments in mycology during 2023, featuring updates from international fungal research conferences held around the world. It covers new awards recognizing fungal research including innovative uses of fungi for environmental cleanup and sustainable energy storage. The report also discusses emerging therapeutic uses of psilocybin-containing mushrooms for treating depression and anxiety, and emphasizes the importance of international gatherings for mycologists to share discoveries and collaborate.

Holarctic Species in the Pluteus podospileus Clade: Description of Six New Species and Reassessment of Old Names

mycolabadmin

Scientists have discovered and formally identified six new species of mushrooms in the Pluteus podospileus group that was previously thought to be a single variable species across the Northern Hemisphere. Using DNA analysis combined with traditional microscopic examination, researchers found that what was once considered one widespread species is actually multiple distinct species with different geographic distributions in Europe, Asia, and North America. The study also resurrected an old, forgotten species name and clarified the relationships between various populations of these small brown mushrooms that grow on decaying wood in forests.

New Species of Ascomycetes from Two Hypersaline Endorheic Lagoon Complexes in Zaragoza Province (Aragon Community, Spain)

mycolabadmin

Scientists discovered three new species of fungi living in extremely salty lagoons in Spain. These fungi were identified using both traditional microscopy and DNA analysis. The research also reorganized how some existing fungi are classified scientifically. This study helps us better understand the hidden microbial life in salt lakes around the world.

Isolation and identification of endophytic fungi from Alhagi sparsifolia Shap. and their antibacterial activity

mycolabadmin

Researchers discovered ten types of fungi living inside the medicinal plant Alhagi sparsifolia that were never found before. Two of these fungi produced substances that killed harmful bacteria better than standard antibiotics, especially against E. coli. The researchers identified 26 different compounds in these fungi that are responsible for their antibacterial effects. This research opens new possibilities for developing natural antibacterial medicines from fungal sources.

From seagrass roots to saline soils: discovery of two new genera in Lulworthiales (Sordariomycetes) from osmotically stressed habitats

mycolabadmin

Scientists discovered two previously unknown types of fungi living in extreme salty environments: one in the roots of a seagrass species from Mauritius and another in salt-affected soils in Czechia. Through DNA analysis and microscopic examination, these fungi were formally named as new genera and species belonging to a group of fungi specialized in living in salty conditions. The findings suggest these fungi are more widespread and adaptable than previously thought, challenging the idea that they live only in ocean environments.

Current taxonomic status of the cultivable and uncultivable Paracoccidioides species

mycolabadmin

Paracoccidioides are fungi that cause serious infections in humans and dolphins. Scientists have recently reorganized and renamed these fungi into five different species—three that can be grown in labs and two that cannot. Some previously named species turned out to be invalid due to naming rule violations. This article explains the correct names and classifications that doctors and researchers should use.
