Wraber, 1969).Substratum: rotten, partly moss covered stump of Picea abies. Place: Lower Trenta valley, right bank of river Soa; between villages Soa and Trenta; near Skokar, Trenta 2 abandoned farm house, East Julian Alps, Posoje, Slovenia EC. Comments (pertain to pictures in the Flickr album Crepidotus applanatus): Crepidotus applanatus is one of several tens of small, whitish, pleurotoid fungi growing on decaying wood. Breitenbach (Ref.6) claims that they are nearly indistinguishable in the field based on morphological traits only. Microscopy seems to be a must for proper determination. Fortunately, Crepidotus applanatus has quite characteristic spores. They are sub-globose and spiny. Their diameter is usually about 5-6 . Many sources claim as possible substratum hardwood only. Yet, some claim conifers wood too (Ref. 2, Ref. 3). This find seems to be such an exception. Such finds have been described in the literate as Crepidotus applanatus var. subglobiger. This variant has a little longer spores than those growing on hardwood and slightly different shape of cheilocystidia. nevertheless. Index Fungorum synonymizes this variety with Crepidotus applanatus.The pilei width was up to 3.5 cm and they stretch up to 3 cm away of the substratum, there was no stipe; flesh was hydrophanous, soft and very brittle; taste mild, smell indistinguishable; fungus apparently causing brown rot; SP abundant, deep ochre-brown, oac797.Spores are sub-globose to globose and distinctly verrucose.

Megacollybia platyphylla (Pers.) Kotl. & Pouzar, syn.: Collybia platyphylla (Pers.) P. Kumm., Clitocybula platyphylla (Pers.) E. Ludw., Oudemansiella platyphylla (Pers.) Moser, Tricholomopsis platyphya and many othersPlatterful mushroom, Whitelaced Shank, DE: Gewhnliches Breitblatt, Breitbltriger RblingSlo.: irokolistna velekorenovkaDat.: July 26. 2017Lat.: 46.35959 Long.: 13.70122Code: Bot_1077/2017_DSC8488Habitat: mixed wood, Fagus sylvatica and Picea abies dominant trees with some Ostrya carpinifolia and Fraxinus ornus; slightly inclined mountain slope, SE aspect; old colluvial, calcareous ground, in shade, dry and relatively warm place; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.950), alpine phytogeographical region.Substratum: heavily rotten, moss covered stump of Fagus sylvatica. Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa; near the trail from Trenta 2b to Strgulc farmhouse, Soa 48; East Julian Alps, Posoje, Slovenia EC.Comments: When I noticed this fungus I thought it was a kind of Pluteus (actually Pluteus cervinus (Schaeff.) P. Kumm. looks very similar). However, neither its spore print nor gills showed even a trace of pinkish color. So, it must be almost for sure Megacollybia platyphylla. Its streaked-looking gray-brown cap is typical.Genus Megacollybia was considered monophyletic (that is containing only one specie - Megacollybia platyphylla) not so far ago. Recent DNA sequencing in North America (Ref.3) showed that it can be separated to several distinct species (how many of them scientists do not agree, up to nine worldwide). One of them Megacollybia platyphylla was limited to Europe. Unfortunately newly recognized species in North America cannot practically be separated by macro-morphological traits (particularly not if geographic location is dismissed as a 'character'). They are all variable and all look alike. Even microscopy doesn't help. To determine them in the field one would need 'pocket DNA sequencer' (which doesn't exist). So it is: DNA-defined species do not always show observable differences in physical features. Megacollybia platyphylla is a common mushroom. There are conflicting reports about edibility of it. Some consider it conditionally edible, some weakly poisonous. Description of this find: Growing solitary; heavily eaten by snails; pileus diameter 13 cm, radially streaked, strakes peel off easily; trama thin, gills broad, beige, fragile; stipe 8 cm long, 23 mm in diameter at the base and 19 mm on top, firm, slightly hollow at the center, fibrous, firmly attached to the rotten wood by mycelial strands; smell slightly on sour bread, taste mild, indistinctive; SP faint, beige, oac814.Spores smooth. Dimensions: 7.3 [8 ; 8.3] 9 x 5.9 [6.5 ; 6.8] 7.4 microns; Q = 1.1 [1.2] 1.4; N = 30; C = 95%; Me = 8.1 x 6.7 microns; Qe = 1.2.
