Specimen notes
Public Note:
taste mild, spore print white, smell strong earthy. Cap a loose cutis. Clamped. Spores strongly amyloid and warted and with an apiculus remaining inamyloid. Spores 7.8-9.1(8.4) SD0.5 x 4.5-5.4(4.9) SD0.3. Holotype of albissimus has smaller spores according to Bigelow and no cystidia. The jury seems to be out on the synonymy of cerealis, paradoxus and albissimus. NM splits paradoxus from ceralis/albissimus on decurrent gills in latter. For FAN this would be L. cutefractus split from paradoxus because former has cheilocystidia (but doesn't mention possible relationship to var. piceina). Cutefractus has different cap surface. BFF has paradoxus without cheilocystidia. Spores are correct size for cutefractus & paradoxus. L. cerealis var. piceinus (recorded for NZ) has a bitter taste but does have cystidia. A mess as usual. My hunch is that spores and cystidia are variable and this is all one taxon (albissimus 1873 USA, paradoxus 1896 France, cerealis 1829 germany, cutefractus 1983, piceina 1904, so the correct name is cerealis). See also Mycotaxon v109, p469 where these taxa are discussed. Note that L. monticola (which used to be a var. of albissimus until raised in rank) does not have decurrent gills, and this taxon does. Sequences indicate a difference between Euro cerealis and USA albissimat axa
