Summary
A new mushroom variety, Pluteus aurantiorugosus var. aurantiovelatus, is identified in Italy. It is distinguished by its unique, ornamented stipe featuring reddish-orange partial veil remnants.
Area of Science:
- Mycology
- Botany
- Biodiversity research
Background:
- The genus Pluteus comprises numerous species, often requiring detailed morphological and molecular analysis for accurate identification.
- Variations within species can present diagnostic challenges, necessitating robust taxonomic methods.
Purpose of the Study:
- To formally describe a new variety of Pluteus aurantiorugosus from Italy.
- To differentiate this new taxon using both morphological characteristics and molecular data.
- To contribute to the understanding of veil presence in the genus Pluteus.
Main Methods:
- Morphological examination of fungal specimens.
- Molecular analysis using Internal Transcribed Spacer ribosomal DNA (ITS rDNA) sequences.
- Comparative taxonomy within the Pluteus genus.
Main Results:
- Description of Pluteus aurantiorugosus var. aurantiovelatus var. nov.
- Identification of key diagnostic features, including an ornamented stipe with reddish-orange partial veil remnants.
- Phylogenetic placement supported by ITS rDNA data.
Conclusions:
- Pluteus aurantiorugosus var. aurantiovelatus is a distinct taxonomic entity.
- The presence and characteristics of the partial veil are important for Pluteus taxonomy.
- This finding expands the known diversity of the Pluteus genus in Italy.

In a multicellular organism, cells must communicate to work together in a coordinated manner. One way that cells communicate is through direct contact with other cells. The points of contact that connect adjacent cells are called intercellular junctions.
Intercellular junctions are a feature of fungal, plant, and animal cells. However, different types of junctions are found in different kinds of cells. Intercellular junctions found in animal cells include tight junctions, gap junctions, and...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
