Nucletmycea

This week’s podcast begins with a riddle about a life form that’s all around us, yet rarely seen. Working under cover, it sends its ghostly tendrils into almost every corner of the terrestrial world. We associate it with death and decay, but life as we know it would be impossible without it. Come for a walk in the woods with Ari Daniel Shapiro and learn how this mysterious form of life, neither animal nor vegetable, shapes our world. Download a transcript of this podcast read moreDuration: 5:29Published: Wed, 02 May 2012 14:22:48 +0000

[taxonomy:genus=Nuclearia] Nuclearia is a naked filose amoeba. The filose pseudopodia are involved in feeding and locomotion, and are constantly growing and retracting. This video illustrates the wavy or bent appearance that the filopodia take when they are retracting. Date: 16 Aug 2011 Location: Freshwater fish pond in concrete tank, outside Life Science Lab 7. Walls were covered in filamentous cyanobacteria, and the bottom with fish waste. Water was mostly clear. Microscope: Bright-field with closed condenser aperture. Camera: Nikon D7000

Place: North of Cerknica lake; SE of village Laze pri Gornjem jezeru; between hills marni gri, 768 m and Sovinek, 780 m, Notranjska, Slovenia EC. Comments: Steccherinum subcrinale is a loosely attached to its substratum, resupinate, effused teeth fungus. It can be distinguished from other Steccherinum species (in my region Steccherinum ochraceum and Steccherinum fimbriatum) by short, from (0.2)0.3 to 0.5(0.6) mm long cylindrical aculei (spines or teeth). Alternative species have pointed, conical (and mostly larger) 'spines'. The same seems true for similar species of genus Irpex. Steccherinum subcrinale also never forms shelf-like, small pilei but remains strictly resupinate.Steccherinum subcrinale is a rare species everywhere in Europe and denoted 'extremely rare' in Germany (Krieglsteiner 2000), Italy (Bernicchia 2010) and north Europe (Eriksson et al 1984). It is listed neither in Poler ed. 1998 nor in Ogris 2008 for Slovenia. Unfortunately, at the time I photographed this observation I was unaware what it might be and I didn't take samples to do microscopy and make exsiccate. Hence the determination remains uncertain although macroscopic traits from photos seem to fit quite good.Ref.: (1) G.J.

Substratum: vertical to steeply inclined surface of limestone rocks, west-southwest exposition.Place: Southwest of village Olib; next to the trail to Banjve bay; Island Olib; Kvarner bay, Adriatic Sea, Croatia EC. Comment: This was a beautiful and interesting find. The lichen is very conspicuous because of its deep orange color and considerable size. Several specimens were found in the vicinity. Also its taxonomy is interesting. After Smith (2009) it should be named Xanthoria aureola. However, this name has been long time used (and is still so by many) for another very similar specimen Xanthoria calcicola Oxner. Many (Ref.:2) would rather call them and also do so (Ref.:3) Xanthoria ectaneoides. They claim that the name Xanthoria aureola opposes the Article 57 of the International Code of Botanical Nomenclature. Other consider this species only as a 'kind of' very common Xanthoria parietina. The result is a considerable confusion in naming. Be that as it may Xanthoria calcicola differs from Xanthoria aureola by densely isidiate central part of the thallus (see Ref.: 7) and less strap-shaped and sparsely overlapping thallus terminal lobes (Smith 2009). Smith (2009) considers this species as Western European species and GBIF map confirms this by showing most of observations along west coasts from north Scandinavia to Canary Islands and with a few exceptions in Germany (a single specimen now in herbarium Berlin), on Crete and several finds in Italy (Ref.:6). Almost all finds are close to sea shores.What puzzles me with this observation is the center of the thallus on picture 2b, upper part. The thallus is 'bumpy' there and this bumps may eventually be interpreted as isidia. I am not sure. If so, this would not fit to Xanthoria aureola. Also, Smith lists ' siliceous or, rarely, basic rock ' as a most common substratum, while Dobson 2005 doesn't list siliceous rock as an option, but eventually allows basic rock. This find was surely found on calcareous, basic rock. The lichen was photographed in completely dry state. Unfortunately, no chemical tests and microscopy have been done.Ref.:(1) C.W.Smith, et all, The lichens of Great Britain and Ireland,The British Lichen Society,(2009), p 968.(2) www.lichens.lastdragon.org/Xanthoria_aureola.html (accessed April 3. 2018) (3) F.S.
