Observation 132696: Hypholoma fasciculare var. pusillum J.E. Lange

Code: Bot_705/2013_IMG3010

Habitat: Light, mixed, predominantly hardwood woodland, moderately south-west oriented hill side, cretaceous clastic rock (flysh), partly protected from direct rain by the log and tree canopies, mostly in shade, average precipitations ~3.000 mm/year, average temperature 8-10 deg C, elevation 490 m (1.600 feet), alpine phytogeographical region.

Substratum: a large log of (most probably) a deciduous tree laying on ground, in the last stage of disintegration.

Place: Bovec basin, on southwest slope of the hill Rabeljnik, East Julian Alps, Posočje, Slovenia EC

Comments: Growing solitary and clustered, pileus diameter 1.5-3(4.5) cm, stipe 2-3.5(5) cm long and curved, 4-8 mm in diameter; flesh brittle, fibrous; SP dark brown with purple-violet tint (oac526). Smaller fruitbodies than of typical form, spring time growth and partly solitary appearance (in addition to clustered growth) should distinguish this subspecies from standard form of H. fasciculare var. fasciculare. H. fasciculare is common where I live, however it is most frequent in autumn and about twice as large. I’ve never seen so small fruitbodies so early in the season yet.
