“…Similar to C. aegerita PHF strains in artificial culture [17], V. volvacea is capable of a homothallic life cycle by homomultikaryotization of fruiting-competent homokaryons growing from mononucleate meiotic homokaryotic basidiospores [36]. As in C. aegerita where PHF basidiomes exhibit four-spored basidia [17], basidia from basidiomes formed by V. volvacea hetero-or homokaryons are reported to be mostly four-spored (some are one-, two-, three-, and five-spored), showing typical meiotic stages and chiefly (>85%) mononucleate spores [37][38][39][40][41][42]. In contrast, monokaryotic fruiting s.str.…”

Cyclocybe parasitica is a wood-destroying parasitic edible mushroom growing on diverse broad-leafed trees in New Zealand and other Pacific areas. Recent molecular systematics of European Cyclocybe aegerita, a newly delimited Asian phylum and of related species, corroborated the distinction of the chiefly saprobic cultivated edible mushroom C. aegerita from C. parasitica. Here, we show that C. parasitica exhibits a morpho-physiological trait characteristic to its European cousin, i.e., monokaryotic fruiting sensu stricto (basidiome formation without mating). Monokaryotic fruiting structures formed by C. parasitica ICMP 11668-derived monokaryons were categorized into four phenotypes. One of them displays ulcer-like structures previously reported from bracket fungi. Histology of dikaryotic and monokaryotic C. parasitica fruiting structures revealed anatomical commonalities and differences between them, and towards monokaryotic fruiting structures of C. aegerita. Mating experiments with C. parasitica strains representative of each fruiting phenotype identified compatible sibling monokaryons. Given reports on hypothetically monokaryotic basidiome field populations of ‘C. aegerita sensu lato’, it seems worthwhile to prospectively investigate whether monokaryotic fruiting s.str. occurs in nature. Sampling from such populations including karyotyping, comparative -omics, and competition assays may help to answer this question and provide evidence whether this trait may confer competitive advantages to a species capable of it.

“…The biological efficiency of strain v9 was 26.3%, which was higher than strain v26 (22.3%) ( Figure 1C). Three development stage periods were measured (egg stage, elongation stage and mature stage) [18]. In the egg stage, the stipe was hidden and ovoid; in the elongation stage, the stipe was stretched out of the universal veil and the pileus was not opened; in the mature stage, the pileus was fully expanded.…”

“…The microorganisms used in the current study were maintained on potato dextrose agar (PDA, Merck, Germany) at 30 • C. The mycelial growth rate was determined in a Petri dish with a diameter of 9 cm. A 0.5 cm 2 mycelial agar plug was transferred into the center of a fresh PDA plate and the colonies' radii were measured every 24 h. Straw mushroom strains were cultivated on mixed substrates including 50% rice straw and 50% waste cotton (each with 65% water content) at 30 • C. Various developmental stages of V. volvacea were differentiated using the methods described previously by Chang and Yau [18]. At least 10 replicates for each stage were analyzed.…”

The edible straw mushroom, Volvariella volvacea, is one of the most important cultivated mushrooms in tropical and sub-tropical regions. Strain improvement for V. volvacea is difficult because of the unknown mechanisms involved in its growth regulation and substrate utilization. A comparative physiological and transcriptomic study was conducted between two commercially available straw mushroom strains (v9 and v26) to explore their fast-growth regulation mechanism(s). The physiological study showed that V. volvacea v9 had a shorter growth cycle and higher biological efficiency (4% higher) than that in v26. At least 14,556 unigenes were obtained from the four cDNA libraries (two replicates per strain). Among them, the expression of 1597 unigenes was up-regulated while 1352 were down-regulated. Four heat-shock proteins were highly expressed in v9, showing that v9 has the better ability to handle stresses and/or environmental changes. Moreover, up to 14 putative transporter genes were expressed at a higher level in v9 than those in v26, implying that v9 has a better ability to transport nutrients or export xenobiotics efficiently. Our report allows to identify the candidate genes involved in the fast growth requirement of V. volvacea, which represents a valuable resource for strain improvement in this commercially important edible mushroom.

Paddy straw mushroom (Volvariella volvacea), commonly known as the straw mushroom, or the Chinese mushroom, belongs to the family Pluteaceae (Kotl. & Pouz) of the Basidiomycetes (Singer, 1961). The present research was undertaken to explore the diversity, distribution, morphological, and microscopic characteristics of V. volvacea native isolates from Chhattisgarh.A total of eight isolates were collected in a survey conducted across Chhattisgarh from six districts viz. Rajnandgaon, Raipur, Dhamtari, and Bemetara, Kabirdham, Durg and all the relevant information on habitat, temperature, relative humidity, location (GPS data), habit, and related substrates in native environments; were recorded delligently. Volvariella isolates collected were characterized morphologically and found possessing pink spores, free lamellae, and a stipe bearing no annulus but was encased at the base by a volva. The gills of all the isolates were freely arranged; consistency was fleshy; colour was moderate brown; and texture was smooth. The stipes of all the isolates were cylindrical, centrally attached to the pileus; the consistency was fleshy; the colour was yellowish white; and the bases were swollen. Pileus characters of all isolates show a light brown outer colour, a moderate brown middle colour, and regular margins. The volva characters of all isolates show a sheathed arrangement and brownish colour. Spore print colours were observed as pink and moderate brown, gill colour varied from light pink to brown for all isolates. Microscopic characterization was done and was found that spore size of all collected isolates ranges between six to nine micrometre and the basidium bears sterigmata.
