Dictydiaethalium plumbeum

Dictydiaethalium plumbeum


Plasmodium bright pink. Pseudoaethalium formed of a single layer of closely-appressed, beige or ochraceous sporothecae. The peridium of each individual sporotheca consists of a polyhedral cap with a vertical thread running from each corner to the base of the pseudoaethalium. Spores 8-10 µm diam., spinose, the spines up to c. 1 µm high. The corticolous form of this sp. was described and figured in Y. Yamam. && Nann.-Bremek. 1995 'Additions to the Myxomycetes of Japan' Proc. Kon. Ned. Akad. v. Wetensch. 98(3):321-322 under the name Enteridium japonicum. Reticularia aurea Nann.-Bremek. 1996 in 'Notes on Myxomycetes X' Proc. Kon. Ned. Akad. v. Wetensch. 69(3):336-349, may also represent a bark form of D. plumbeum -----Members of the Enteridiaceae family generally produce either aethalia or pseudoaethalia fruiting bodies, which very in size from 3 mm to 15 mm. Some of which are common and brightly coloured like Lycogala epidendrum which is often encountered while others are not


.-AETHALIUM: pulvinate, smooth, flattened, 1 to 10 cm. across, 0.5 to 1 mm. thick, olivaceous or ochraceous, areolated with the convex apices of the sporangia, usually surrounded by a white, membranous hypothallus; sporangia cylindrical, angled by mutual pressure, 0.5 to 1 mm. high, 0.2 mm. broad. -PLASMODIUM: Rose red. -HABITAT: Decaying wood. -DISTRIBUTION: Cosmopolitan ( )---> hiddenforest, ( )--> discoverlife


(When not "tubifera ferruginosa" (unlikely) , then i could only come up with " dictydiaethalium plumbeum" (not confirmed and sure). Here ( ) the spore-pictures of this specimen)---question, cleared and closed!! thanks clive shirley

thanks clive, i was even more unsure, since i'm still less expert than you. Expert are for me people, which can explain their research to normal people without using latin-expert-terms. And i think, here at pn are some people, which are more expert, than the guys, who get offical called so. Therefore you are,for me an expert, appreciate your expertise
