Cenococcum is present in samples from a 17th century byre used to collect dung. Material from heathlands was collected to absorb the matter for manuring fields. It is of relevance seeing written sources whether the collected material included the subsoil, or only the heathland vegetation. If Cenococcum is common in such habitats, they would be expected if subsoil was included.
Dear Otto,
from the literature it seems, that Cenococcum is to be expected to be very common on dry and sandy soils. See for instance LoBuglio KF (1999, Cenococcum. In: Cairney J, Chambers S (eds) Ectomycorrhizal Fungi Key Genera in Profile. Springer Berlin Heidelberg, pp 287-309) or Ferdinandsen (1925, abstract: http://www.cabdirect.org/abstracts/19261100585.html;jsessionid=6FC06E1B9AD1348AA2A011D1DB9F0D04;jsessionid=3F68F02FC3B1E653FD79508E21864FA8?freeview=true).
Best wishes
Frank
Hello Otto,
I don’t know about the spores of Cenococcum geophilum but I notice the sclerotia quite often in our archaeobotanical samples. Often in samples with deteriorated (wood) peat as a matrix. Particularly while looking for C14 material in such (disastrous) samples, there will be often just few fruits of Alnus glutinosa and many sclerotia of Cenococcum geophilum. However, they are also to be found in samples from sandy soils; here they will be accompanied by roots/stem bases of Ericaceae. Hope it helps a litte.
All the best, Lucy
Dear Otto,
I have found them fréquently in the humic layer of sandy soil in northern Schleswig-Holstein, Germany, but here in eastern France they are really very rare - we have here clayey/loamy soils on Keuper or calcaerous soils on limestone...
This suggests that they occur mainly on sandy and more acidic soil types as Lucy already pointed out....
Kind regards
Julian
