“…This result was similar to those of previous studies which reported that a casing layer or casing soil overlaying the substrate was a necessary step in the primordia formation of P. portentosus [9,27,68]. Notably, a casing layer was a crucial step in the formation of a fruiting body and could effectively increase the productivity yield of some saprobic mushrooms, e.g., Agaricus bisporus, Agaricus subufescens, Coprinus comatus, Grifola frondosa and Stropharia rugosoannulata [70][71][72]. In this study, the primordia of P. spongiosus were successfully developed to mature fruiting bodies.…”

A New Report on Edible Tropical Bolete,Phlebopus spongiosusin Thailand and Its Fruiting Body Formation without the Need for a Host Plant

Phlebopus spongiosus is a well-known edible ectomycorrhizal mushroom indigenous to southern Vietnam. The mushroom specimens collected from northern Thailand in this study were identified as P. spongiosus. This identification was based on morphological characteristics and the multi-gene phylogenetic analyses. Pure cultures were isolated and the relevant suitable mycelial growth conditions were investigated. The results indicated that the fungal mycelia grew well on L-modified Melin-Norkans, and Murashige and Skoog agar all of which were adjusted to a pH of 5.0 at 30 C. Sclerotia-like structures were observed on cultures. The ability of this mushroom to produce fruiting bodies in the absence of a host plant was determined by employing a bag cultivation method. Fungal mycelia completely covered the cultivation substrate after 90-95 days following inoculation of mushroom spawn. Under the mushroom house conditions, the highest amount of primordial formation was observed after 10-15 days at a casing with soil:vermiculite (1:1, v/v). The primordia developed into a mature stage within one week. Moreover, identification of the cultivated fruiting bodies was confirmed by both morphological and molecular methods. This is the first record of P. spongiosus found in Thailand and its ability to form fruiting bodies without a host plant.

“…In the present manuscript, the highest yields were obtained in the 2nd (media of 6.54%) and 3rd flushes (media of 4.08%) ( Table 3). Other authors have also verified the low yield in the 1st flush and the long cycle of crop (Zied and Minhoni, 2009;Colauto et al, 2011;Zied et al, 2011b;Pardo-Giménez et al, 2014;Martos et al, 2017).…”

The aim of this study was to analyse the viability of supplementation of Agaricus subrufescens compost with different organic materials, using three commercial strains.Compost was prepared by the traditional method and was used as a control (without supplementation). Six supplements were applied and can be separated into four categories: (i) commercial supplements (recommended to Agaricus bisporus and Pleurotus ostreatus); (ii) supplements based on agro-industrial waste (provided by peanut and acerola juice); (iii) supplements based on noble grains (a mix with bran of soybean, corn, and cotton); and (iv) a blend of supplements (ii) and (iii) (peanut waste, acerola juice waste, and noble grains-a mixture of 33.3% each). The results showed that the practice of supplementation is an important tool to improve the yield in the industrial production of A. subrufescens. Waste materials and noble grains can be selected as quality supplements. The use of appropriated strains is essential for the success of the supplementation practice.

“…Our biological efficiencies (57.84%, rapid induction; and 54.81%, slow induction) were better than other reports that managed the temperatures of primordia initiation differently. Martos et al 43 obtained a biological efficiency of 40.0, 38.0 and 39.6% when the temperature was lowered to 16 °C and then maintained for 4, 6 and 8 days, respectively. Wang et al 19 maintained a constant temperature between 24 and 26 °C with the highest biological efficiency being 41.4% over a cultivation period of 120 days of 6 flushes.…”

new species of medicinal mushrooms have emerged over the past several decades, such as the Sun mushroom, Agaricus subrufescens. Horticultural improvements are required to shift its cultivation from small-scale local production to large-scale international production. the research reported here evaluated the agronomic behavior and the chemical characteristics of the Sun mushroom as a function of i) nutritional supplementation ii) ruffling of the casing layer and iii) the temperature management on the primordia induction and reduction of the crop cycle. Supplementation was beneficial for yield, unit mushroom weigh and decrease in time to first harvest. Supplementation improved biological efficiency with Champfood providing a yield increase of 15% over the non-supplemented compost. Among the supplements only Promycel increased the individual mushroom weight. Ruffling overall improved the yield in the 2 nd and 4 th flush. Already biological efficiency was greater by 21%. The highest yield harvested in any single day in the crop occurred in 3 rd flush with the amount of 2.484 kg of mushrooms per m 2 for the rapid induction method. Still the biological efficiency was not significantly affected by the mushroom induction temperature method. only the fat content of the mushrooms was positively affected by the rapid induction of primordia. Champfood supplement promotes a reduction in the value of earliness and an increase of 1 st flush yield. The ruffling technique provided an increase in biological efficiency due to the great number of mushrooms harvested. Rapid primordia induction allowed the crop cycle to end 3 days earlier than the slow primordia induction, providing a higher production rate. New species of medicinal mushrooms have emerged over the past decades. One such mushroom is the Sun mushroom, reported as Agaricus subrufescens Peck, Agaricus brasiliensis Wasser et al. and Agaricus blazei (Murrill) ss. Heinemann 1-4. This species has been cultivated on a small-farm scale in Brazil for many years. In 2017 Royse et al. 5 reported that world mushroom production is divided among several genera: Lentinula (22%), Pleurotus (19%), Auricularia (18%), Agaricus (15%), Flammulina (11%), Volvariella (5%) and others (10%). In the discussion of Agaricus these authors did not mention the Sun mushroom. In 2018 Sanchez et al. 6 noted that the only country in the Americas that cultivated the Sun mushroom was Brazil. Agaricus subrufescens along with Pleurotus eryngii, Flammulina velutipes and other non-Agaricus represented only 6% of the total production in Brazil. Changes in horticultural technologies are required to shift production from small-scale local producers to large-scale commercial production with international markets. Two main challenges in the cultivation of Sun mushroom are the compost nutrition and its long cultivation cycle 7,8. Production of A. subrufescens generally follows that of Agsricus bisporus. Despite this, the cultivation of the button mushroom has a much shorter cultivation cycle and a much higher yield....
