“…The LIV has been implicated in causing mycelial degeneration and substantial yield reductions in A. biporus [ 35 ]. The MVX can destroy the primordium, leading to premature opening, discoloration, and malformed fruiting bodies of A. biporus [ 21 , 36 ]. In L. edodes , LePV1 has been associated with manifestations of both mycelial degradation and abnormal fruiting body formation [ 37 ].…”

Mycoviruses are usually transmitted horizontally via hyphal anastomosis and vertically through sporulation in natural settings. Oyster mushroom spherical virus (OMSV) is a mycovirus that infects Pleurotus ostreatus, with horizontal transmission via hyphal anastomosis. However, whether OMSV can be vertically transmitted is unclear. This study aimed to investigate the transmission characteristics of OMSV to progeny via basidiospores and horizontally to a new host. A total of 37 single-basidiospore offspring were obtained from OMSV-infected P. ostreatus and Pleurotus pulmonarius for Western blot detection of OMSV. The OMSV-carrying rate among monokaryotic isolates was 19% in P. ostreatus and 44% in P. pulmonarius. Then, OMSV-free and OMSV-infected monokaryotic isolates were selected for hybridization with harvested dikaryotic progeny strains. Western blot analyses of the offspring revealed that the OMSV transmission efficiency was 50% in P. ostreatus and 75% in P. pulmonarius, indicating vertical transmission via sexual basidiospores. Furthermore, we observed the horizontal transfer of OMSV from P. pulmonarius to Pleurotus floridanus. OMSV infection in P. floridanus resulted in significant inhibition of mycelial growth and yield loss. This study was novel in reporting the vertical transmission of OMSV through basidiospores, and its infection and pathogenicity in a new host P. floridanus.

Ever since their discovery just about 56 years ago in the cultivated mushroom , many more viruses infecting fungi have been identified in a wide range of fungal taxa. With mostly being asymptomatic, especially the ones that are detrimental to their phytopathogenic hosts are intensively studied due to their considerable importance in developing novel plant protection measures. Contrary to the rapid accumulation of notable data on viruses of plant pathogenic microfungi, much less information have hitherto been obtained in regards to the viruses whose hosts are macrofungi. According to the current literature, only more than 80 distinct viruses bearing either linear dsRNA or linear positive sense ssRNA genome and infecting a total number of 34 macrofungal species represented with four and 30 have been identified so far. Among these 34 macrofungal species, 14 are cultivated edible and wild edible mushroom species. According to the 10th ICTV (International Committee on Taxonomy of Viruses) Report, macrofungal viruses with linear dsRNA genome are classified into five families (, ,, and) and macrofungal viruses with linear positive sense ssRNA genome are classified into seven families (, ,, ,, and). In this review, following a brief overview of some general characteristics of fungal viruses, an up to date knowledge on viruses infecting macrofungal hosts were presented by summarizing the previous, recent and prospective studies of the field.
