Hypholoma-fasciculare-var-pusillum_10

Description:

Hypholoma fasciculare var. pusillum, syn.: Hypholoma fasciculare var. subviride (Berkeley & Curtis) (?), Naematoloma fascicularis, Psilocybe fascicularisEN: Sulfur Tuft, DE: Zwerg-SchwefelkopfSlo.: navadna veplenjaa, drobceni razliekDat.: April 21. 2013Lat.: 46.335733 Long.: 13.56733Code: 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, Posoje, Slovenia EC Comments: Growing solitary and in groups of many species, pileus diameter 1.5-3(4.5) cm, stipe 2-3.5(5) cm long and curved, 4-8 mm in diameter; taste very bitter, long lasting, not burning; smell indistinctive mushroomy; flesh brittle, fibrous; SP dark brown with purple-violet tint (oac526). Smaller fruitbodies, spring time growth and solitary appearance (in addition to clustered growth) should distinguish this subspecies from standard form of H. fasciculare. H. fasciculare is common where I live, however it is most frequent in fall and about twice as large. I've never seen so small fruitbodies so early in the season yet. Spores smooth, dark, brown with violet tint, with pores. Dimensions: 6.5 (SD = 0.4) x 4.3 (SD = 0.3) , Q = 1.5 (SD = 0.07), n = 30.
