Dear Friends,

This time a totally new species on TN (and also a quite young one for the science): Xerocomus marekii (Šutara & Skála) Klofac, a very rare bolete species. I'd like to dedicate the photo to my American Friend John Denk (jpdenk), who I learned a lot from. Dear John, sharing a species not living in North America, I hope I can teach something to You now. :)

Xerocomus marekii was discovered as a new species by the Czech mycologists Šutara and Skála in 2005. It's quite similar to its closest relative, Xerocomus porosporus Imler, except for the cap color and some microscopical features.

Xerocomus marekii (Šutara & Skála) Klofac

Cap: diameter 2,5 - 4,5 centimeters, from hemispherical expanding, applanate, felty when young, soon cracking strongly. Color rosaceous red, bloodred, very rarely yellow, often with yellowish margin, with brownish tinges by the older specimens.
Pores: broad, adnexed with small pit, labyrinthoid when young, later with angular, wide pores, lemon yellow, turning greenish blue when bruised, olivaceous green when mature.
Stem: 3-6 x 0,4-0,8 centimeters, cylindrical, curved, tapering towards the base, with red-ish floccosity on yellow ground in different degree, greyish brown at the base.
Context: thin, soon becoming soft, bright yellow in pileus (cap), pale yellow in stem, differently red towards the base, greyish brown at the base.
Habitat: in mixed deciduous forests, under oaks (Quercus sp.). Found mostly in Middle of Europe (Czech Republic, Slovakia, Germany, Austria, Hungary, but was also reported from Greece).
Edibility: very probably edible, because no toxic species is known in Xerocomus genera.

(source: Albert, L.; Dima, B.: First occurence of Xerocomus marekii in Hungary, in: Clusiana vol. 48., No. 1., 2009)

I found the specimen on the pic on 30th of May, 2010, under Quercus petraea (sessile oak). This is the 2nd place in Hungary where Xerocomus marekii was found. Microscopical analysis was done by my friend Bálint Dima mycologist.

I uploaded a collage as workshop to show all the macroscopic features.

More studies on the taxon here.

Thanx for stopping by and commenting. Cheers, László

Ciao Ladislao,
oggi siamo vicini e mi rallegra l'immagine di questo fungo ripreso in una splendida visione grandangolare che esalta le sue caratteristiche, mi piacerebbe fotograre i funghi, ma pur essendo originario di una zona montana delle Prealpi, non ho molte occasioni per farlo, grazie quindi della condivisione dei tuoi meravigliosi soggetti.
Buona domenica
Ciao Maurizio

Hi Laszlo.
Great use of DOF. Blurriness of the surroundings are superb and very pleasant for eyes. Ultimate details and sharpness of the mushrooms cap are also exceptional. Colors are looks so naturally and very nice too. Perfect close-up work. My compliments.

Buzogány Laszlo,

We come back to the period of the mushrooms, certainly after the a lot rain the last month, the fourth most bad month since 1833 in Belgium.
Nice pose, very low against the ground taken
Very well sharpness and clarity. TFS.

Warmest regards,
John.

Hello MF Laszlo,
very artistic composition with the selected focussing to give a dramatic composition.
I like delicate brown cap that stands outs beautifully in the photo.
Well shown fungus.

regards,
Foozi

Hello Laszlo,

this specie are rare in the Netherlands and protected.
Also Red listed.
Nice dof, good pov and sharpness.
Fine colours.
I never been found this specie.
Where i take a lots of red flowers (South limburg)he are uncommon.

Gert

Hello Laszlo,

This is a fine discovery. I should check next year for this specie in my area too, since my location is close both to Hungary and Slovakia... I'll do a bookmark to this page to have at least the macroscopic features. The microscopic will be a problem though...

Cheers, Petru

Have a joyful Christmas, László.
This is a fine close macro of the new species in TN. Details are amazing in artistic focus and presentation.
Thanks and kind regards - Jusni

A beautiful mushroom and an attractive, elegant image. Redccing the photo to just the mushroom and its uncluttered habitat works very well! And thank you for the dedication, László! I've learned from your postings too, which is what I think this site should primarily be about.

Thanks,
John
