Abstract
A recent publication in Botany introduced two new taxa: a fossil orchid seed (Mycophoris) and a fossilized basidiomycete fungus (Synaptomitus) in an alleged relationship with this orchid, encased in 15–20 million year old Dominican amber (Poinar, G. 2017. Two new genera, Mycophoris gen. nov., (Orchidaceae) and Synaptomitus gen. nov. (Basidiomycota) based on a fossil seed with developing embryo and associated fungus in Dominican amber. Botany, 95: 1–8). From the working knowledge of extant orchid seeds, seedlings, and mycorrhiza shared among us, we cannot support these interpretations. Here we analyse: (i) why Mycophoris may not be an orchid seed, (ii) why Mycophoris is not a germinating seed, (iii) why fungal hyphae and a symbiotic fungus are absent in Mycophoris, and (iv) why Synaptomitus is likely not a fossil basidiomycete.
