“…( Spegazzini 1899) but unfortunately there are no molecular data, and as far as we know, no modern collections, for this species. The author of the species later placed V. argentina in synonymy with Volvariella parvula ( Spegazzini 1926), which is accepted by most modern authors ( Boekhout, 1990, Shaffer, 1957, Shaffer, 1962and Singer, 1986 as a synonym of Volvariella pusilla. After studying the type collection of V. argentina, Shaffer (1962) found no morphological differences between this species and modern collections of V. pusilla.…”

“…According to the revision of the type (Shaffer 1957) there is no gelatinous matrix in the pileipellis. This species is only known from the type collection (U.S.A., FL, Clay Co., Green Cove Springs, March 3, 1926, Murrill FLAS9975).…”

“…According to Shaffer (1957) there is no gelatinous matrix in the pileipellis. The type specimen at NY (U.S.A., AL, Lee Co., Auburn, March 10, 1898) has been destroyed by insects, and only a portion of the pileus is conserved at CUP-A (Shaffer 1957).…”

Phylogeny of the Pluteaceae (Agaricales, Basidiomycota): taxonomy and character evolution

et al. 2011

The phylogeny of the genera traditionally classified in the family Pluteaceae (Agaricales, Basidiomycota) was investigated using molecular data from nuclear ribosomal genes (nSSU, ITS, nLSU) and consequences for taxonomy and character evolution were evaluated. The genus Volvariella is polyphyletic, as most of its representatives fall outside the Pluteoid clade and shows affinities to some hygrophoroid genera (Camarophyllus, Cantharocybe). Volvariella gloiocephala and allies are placed in a different clade, which represents the sister group of Pluteus, and a new generic name, Volvopluteus, is proposed to accommodate these taxa. Characters such as basidiospore size and pileipellis structure can be used to separate Pluteus, Volvariella and Volvopluteus. The genus Pluteus is monophyletic and includes species with partial veil traditionally classified in the genus Chamaeota. The evolution of morphological features used in the infrageneric taxonomy of the genus, such as metuloid cystidia and pileipellis structure, was analyzed. Agreement between the molecular phylogeny and morphological subdivision of Pluteus is, generally speaking, good, though some rearrangements are necessary: (i) species with non-metuloid pleurocystidia and pileipellis as a cutis are placed either in sect. Celluloderma, together with the species characterized by a hymenidermal pipeipellis, or in sect. Pluteus, with the metuloid bearing species; (ii) subdivision of sect. Celluloderma according to the presence/absence of cystidioid elements in the pileipellis is not supported by molecular data.

The phylogeny of several species-complexes of the genera Pluteus and Volvopluteus (Agaricales, Basidiomycota) was investigated using molecular data (ITS) and the consequences for taxonomy, nomenclature and morphological species recognition in these groups were evaluated. Conflicts between morphological and molecular delimitation were detected in sect. Pluteus, especially for taxa in the cervinus-petasatus clade with clamp-connections or white basidiocarps. Some species of sect. Celluloderma are apparently widely distributed in Europe, North America and Asia, either with (P. aurantiorugosus, P. chrysophlebius, P. fenzlii, P. phlebophorus) or without (P. romellii) molecular differentiation in collections from different continents. A lectotype and a supporting epitype are designated for Pluteus cervinus, the type species of the genus. The name Pluteus chrysophlebius is accepted as the correct name for the species in sect. Celluloderma, also known under the names P. admirabilis and P. chrysophaeus. A lectotype is designated for the latter. Pluteus saupei and Pluteus heteromarginatus, from the USA, P. castri, from Russia and Japan, and Volvopluteus asiaticus, from Japan, are described as new. A complete description and a new name, Pluteus losulus, are given for the African P. cervinus var. ealaensis. The American Volvopluteus michiganensis is described in detail. Taxonomic comments and a morphology-based key to all known species of Volvopluteus are provided.

SummaryThe "egg", "elongated" and "mature" stages of Voluariella esculenta (Mass) SINGER sporocarps were analysed for their chemical composition. The "egg" stage was found to contain the richest amount of nutrients and the "elongated" stage the poorest. The "egg" stage was richer in protein, amino acids, lipid, crude fibres, glycogen, sugars, potassium, magnesium, calcium, and phosphorus than the "elongated" and "mature" sporocarp stages. At any sporocarp stage, the pileus contained greater amounts of moisture, sugars, ash, lipid, protein, amino acid, phosphorus, iron, copper and zinc than the stipe while the stipe contained more dry matter, crude fibre, calcium and magnesium.
