Observation 159937: Gloeophyllum abietinum (Bulliard) P. Karsten

Code: Bot_779/2014_DSC9621

Habitat: Steep, rocky mountain slope, open rocks and light mixed wood, Ostrya carprinifolia, Picea abies, Fagus sylvatica, Fraxinus ornus, Corylus avellana dominant trees, calcareous ground, warm, dry, wind exposed place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 655 m (2.150 feet), alpine phytogeographical region.

Substratum: dead, debarked, partly still standing, partly loosely lying on ground, trunk of Picea abies in its initial stage of disintegration.

Place: Lower Trenta valley, next to the trail from village Soča to Lemovlje flats, East Julian Alps, Posočje, Slovenia EC

Comments: Four species of the genus Gloeophyllum have been reported in Slovenia: G. odoratum, G. separium, G. abietinum and G. trabeum. Far the most common is G. odoratum. It is one of the most frequent Polypores in my region. Number of my observations goes in several ten. G. separium follows, while both others are much, much rarer. This observation is my first find of G. abietinum, while I haven’t yet found G. trabeum. Literature states G. abietinum to be rare or very rare in Britain and Europe in general, while Ref.:(3) states it is common in CH. Rivarden and Bernicchia say it is a perennial species, while Breitenbach and Krieglsteiner consider it as an annual species. Also there are two writings of genus name in use – Gloeophyllum and Gloephyllum. Index Fungorum uses the first one.

Growing in groups of many pilei; their dimensions up to 4 × 2 cm, quite thick at the base, pore layer thicker than context; context tough, fibrous; SP faint whitish-ochre, oac858 (?).
