Notes: Code: Bot_705/2013_DSC6028
Habitat: Light, mixed, predominantly hardwood woodland, nearly flat terrain, cretaceous clastic rock (flysh), partly rain protected by trees canopies, mostly in shade, precipitations ~3.000 mm/year, average temperature 8-10 deg C, elevation 490 m (1.600 feet), alpine phytogeographical region.
Substratum: heavily rotten Picea abies trunk laying on ground.
Place: Bovec basin, on top of Rabeljnik hill, East Julian Alps, Posočje, Slovenia EC
Comments: Growing solitary almost at the ground level, however attached to the wood, fruit body diameter 10.5 cm (4.1 inch), smell indistinctive, flesh rubbery but quite brittle when wet and hard and firm when dried; almost no SP, color indistinguishable; upper side of pilei brown-red (oac636), lower side appears waxy, pale whitish brown (oac718).
Measured spores pose a problem. All asci in a tissue sample I examined were sterile. This is not unusual (see Ref.:7.) since fertile asci can be found only in fully mature sporocarps. In spite of that there were several scattered spores found in the sample taken from the fertile surface with a soft wet tip of a brush (picture of the spores is a CS combo!). However, only a few were fusiform with apiculi as it should be the case with Discina ancilis. Their dimensions fit more or less to the expected dimensions. The length of the rest of the spores is OK, but they are significantly too wide and of untypical shape. Possibly they belong to another fungus (?). Oil drops are also missing. Possibly these drops develop only in fully mature spores? Asci and paraphyses dimensions fit to expectations. Very similar Disciotis venosa has much smaller spores and distinct smell on chlorine. It also grows on soil, which was not the case with this observation.
