Clavulina rugosa

Clavulina rugosa (NL: Rimpelige koraalzwam / EN: Wrinkled Club / DE: Runzliger Korallenpilz / FR: Clavaire rugueuse) is a fungus in the Clavulinaceae family. In its "pure" form Clavulina rugosa is fairly easily identified by its unbranched or sparingly branched structure, its white color, its rugged surface, and its blunt branch tips. Fruiting Body's are 4-12 cm high and up to 1.5 cm wide. Its surfaces do not turn green when iron salts are applied, and its microscopic features are distinctive. However, collections are not infrequently made in which the branching is more profuse, the surface is less rugged, and the branch tips become "cristate" like those in Clavulina coralloides. Some experst think that Clavulina coralloides and Clavulina rugosa may represent the extreme ends of a continuum (an idea perhaps supported by the fact that their microscopic features are very similar), which might imply that there is only one species involved. It is presumably a mycorrhizal species found under conifers and hardwoods; growing alone, gregariously, or in clusters. I found this very nicely formed specimen in a group of more than 100, most of them unbranched, and just had to wait for the sun to light the fungus !

Het is hier elke keer weer een verrassing wat voor bijzondere soort je hebt gefotografeerd:-)
Ik vind koraalzwammetjes altijd erg fotogeniek en dus leuk om te fotograferen. Deze staat er zeer fraai op, je had mooi zacht licht, de achtergrond kleurt prachtig bij het zwammetje.

@Lia: Ik hoop ieder jaar weer dat ik enkele exemplaren tegenkom van koraalzwammen ... Ze behoren tot mijn lievelingsonderwerpen als het op paddenstoelen op aan komt. Niet enkel omwille van de relatieve zeldzaamheid, maar zeker ook door de indrukwekkende vormen. Bedankt voor je lovende woorden alweer !

Was soll ich da noch sagen ? Deine Pilze scheinen von innen beleuchtet zu sein !

@Loner: Thanks, Sonja. The woodfloor was rather dark to make images, but I waited about 15 min. for the sunlight to touch the mushroom. I just could make a few images before the sunlight was gone again ... Sometimes a photographer has to be patient ... Greetz for both of you !
