Observation 189234: Exidia recisa (Ditmar) Fr.

Code: Bot_776/2013_DSC9492

Habitat: modestly southeast inclined mountain slope, mixed wood, dominant Fagus Sylvatica, Picea abies; overgrown calcareous ground composed of old alluvial and glacial moraine scree, rocks and boulders, relatively warm and dry place, in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-8 deg C, elevation 595 m (1.950 feet), alpine phytogeographical region.

Substratum: fallen Fagus sylvatica trunk; mostly still in bark in its late initial stage of disintegration.

Place: Lower Trenta valley, between villages Soča and Trenta, near ‘Na melu’ place, East Julian Alps, Posočje, Slovenia EC

Comments: Three sporocarps found growing close together; fresh fruitbodies pinkish-brown, oac651, after two days in refrigerator becoming olive-brown, oac734; fruit body dimensions up to 5 × 4 × 2.5 cm; clumps spreading flat over the substratum and attached to it only at isolated spots resembling rudimentary short ‘stalks’; context quite firm, gelatinous; SP not obtained, only a few (12) spores have been found. This observation looks at macroscopic level like Exidia recisa, but microscopy doesn’t confirm this determination. Spores (which may eventually origin from somewhere else?) do not fit expectations. I was also unable to find small, longitudinally septate, almost globose basidia, which are characteristic to this species (see Ref.: 3). The surface of the blobs looks like a hymenium with ‘regular’ basidia, however without sterigmata. Have no explanation. Hence, this determination can be wrong.
