winter in deadwood, including oak Quercus. Associated with the fungus
Tubercularia confluens in Scandinavia. Ancient woodlands and wood pastures,
although increasingly less so; south and south-east England.
Cerylonidae - Feed on fungal hyphae & spores.
Cerylon fagi Brisout* - Nationally Scarce B. Lives under bark of deadwood and within
decaying heartwood, especially oak Quercus, and especially in later stages of decay.
Also found in beech Fagus and ash Fraxinus. Widespread in lowland Britain and
most frequent in south-east; north to Lanarkshire and west to Devon and Gwent.
Confined to ancient woodlands and wood pastures.
Cerylon ferrugineum Stephens* - Develops beneath bark on dead broad-leaved timber in the
early stages of decay; feed on fungal hyphae and spores. Mostly in ancient woodland
and wood pasture; widespread in Britain, scarce in Ireland.
Cerylon histeroides (Fabricius)* - In fungoid and decaying timber of various broadleaves &
pine Pinus. Mostly in ancient woodland and wood pasture; widespread in Britain,
although most frequent in lowland England; rare in Ireland.
Endomychidae
Symbiotes latus Redtenbacher - Nationally Scarce B. In fungi and under bark on deadwood;
elm Ulmus, poplar Populus, ash Fraxinus, beech Fagus.
Endomychus coccineus (Linnaeus)* - Lives gregariously with its larvae on or around fungoid
growth under bark of dead timber; especially in beech Fagus, but also in apple Malus,
crack willow Salix fragilis, horse chestnut Aesculus, birch Betula.
Corylophidae
Orthoperus mundus Matthews, A.
Orthoperus aequalis Sharp = nitidulus Allen
Orthoperus nigrescens Stephens* - Under fungoid bark.
Lathridiidae - Brown Scavenger or Plaster Beetles. Most feed on mould.
Stephostethus alternans (Mannerheim) – [RDB?]Associated with mouldy bark of broadleaved
trees, especially beech Fagus. Generally rare in central Europe, extending into
northern and western parts; discovered at Dinefwr Deer Park, W. Wales, in 1996,
possibly a recent immigrant.
Cartodere constricta (Gyllenhal) - Under bark on deadwood.
Lathridius consimilis Mannerheim - Nationally Scarce. In fungi on trees, mainly birch
polypore Piptoporus betulinus, also from ash Fraxinus, beech Fagus & elm Ulmus.
Widely scattered across lowland England, with records from SE Devon and
Cardiganshire in the extreme west; 10km square map in Tozer (1973).
Enicmus brevicornis (Mannerheim) - Nationally Scarce. Associated with mouldy bark of
beech Fagus, birch Betula, ash Fraxinus and sycamore Acer pseudoplatanus.
Appears to have increased in numbers and range in recent years through favouring the
development of sooty bark disease Cryptostroma corticale on sycamore. Central and
south-eastern England; also in Cumbria.
Enicmus fungicola Thomson - Nationally Scarce. In ripe powdery slime fungi on oak
Quercus and beech Fagus boughs and trunks.
Enicmus rugosus (Herbst) - Nationally Scarce. In slime mould on trees, often under bark on
deadwood; mainly oak Quercus, but also ash Fraxinus, beech Fagus, alder Alnus and
pine Pinus. Old forest areas: Highlands, Lanarkshire, and central and south-eastern
England.
Enicmus testaceus (Stephens)* - In ripe slime fungus on beech Fagus and other trunks.
