Ischnoderma resinosum (Schrad.) P. Karst., syn.: Fomitopsis resinosa (Schrad.) Rauschert, Ischnoderma fuliginosum (Scop.) Murrill, Ungulina fuliginosa (Scop.) Pat.EN: Resinous Polypore, DE: Laubholz-HarzporlingSlo.: bukova irhovkaDat.: Dec. 3. 2018Lat.: 46.337198 Long.: 13.553608Code: Bot_1168/2018_DSC4494Habitat: cultivated grassland, city park; flat terrain; calcareous ground; partly sunny place; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 450 m (1.480 feet), alpine phytogeographical region.Substratum: dead Acer sp. (personal communication with a resident living next to the place) stump near its final stage of decomposition.Place: Bovec basin, city park in front of the hotel Kanin, East Julian Alps, Posoje, Slovenia EC.Comment: Ischnoderma resinosum is widely distributed and a common species in many regions. But it is a rare find in west Slovenia. This observation seems, at least according to available data from Boletus Informaticus database (Ref.: 8), the first one in Posoje region. Pilei are surprisingly soft for a polypore. When fresh they have very distinctive and pleasant smell resembling the smell of Gloeophyllum odoratum. However, this smell fades after some time and disappears completely in dry herbarium samples. It is interesting that young, but also large, seemingly mature pilei do not yet have hymenium developed and do not produce spores (Ref.: 6). In my first attempt I was trying to do microscopy of both in vain. Only after I went back to the site and bring home a very old, hard, almost decaying pileus I found plentiful spores.Many pilei were present; pilei semicircular to flabelliform, applanate, also effuse-reflexed and sometimes imbricate and confluent, measuring up to 15 x 9 cm, up to 2 cm thick; trama up to 15 mm thick, pore layer up to 10 mm thick; pilei soft; pores small, slightly bruising brownish; SP rather faint, light ocher, oac 847; 5% KOH reaction on pileus almost black with deep purple tint, on pores reddish-brown, on trama brown.Spores smooth. Dimensions: (4,3) 4,8 - 5,6 (5,9) (1,6) 1,8 - 2,2 (2,5) m; Q = (2,3) 2,34 - 2,8 (3,1); N = 40; Me = 5,2 2 m; Qe = 2,6.

But, a kind explanation of Mr. Gnter Sturm, Germany, having long 'mileage' in Polyporaceae, and the paper of David (1974), Ref.: (8) convinced me that the correct determination should be Postia subcaesia. Now substratum fits better. Also habitus of the find fits better to the new determination. Pileus of P. caesia is of more uniform colors and never as strongly zonate as in this observation. Another trait, which fits better now, is the fact that the pilei color didn't changed distinctly blue when bruised. Nevertheless, spore dimensions still don't fit to data from literature. May be Ryvarden's comment in Ref.: (7), p 405, regarding distinguishing both species: 'However, there are some disturbing intermediate specimens on hardwoods.' explains the situation?Former text:[This beautifully blue polypore could eventually be Oligoporus subcaesius. Unfortunately, the distinguishing traits between O. caesius and O. subcaesius seem to be treated quite inconsistently in the literature available to me. Oligoporus caesius should principally thrive on wood of conifers (with rare but documented exceptions) and should have spores wider than 1.5 , while Oligoporus subcaesius is found on broadleaved trees and should have spores narrower than 1.5 (as per Ref.:(5) and Ref.:(1)). Contrary, Ref.: (4) states narrower than 1.5 spores for O. caesius (a typo?). Also the information about spore shape (allantoid versus cylindrical) is inconsistently given in different sources. In this observation measured spore width speaks in favor to O. caesius (according to Ref.:(1) and (5)), while substratum doesn't support this decision. Since exceptions with regard to substratum are known, and based on quite distinctively blue color of the pilei and their size (O. subcaesius should be significantly larger according to Ref.:(1)) I decided for O. caesius, but this may be incorrect. ]Growing in a small group of about 6 pilei of different size; pilei up to 6 x 4 cm across; flesh soft, fibrous; SP very faint, whitish(?), oac857(?).Spores smooth, cylindrical and moderately allantoid.

Also known as Tyromyces caesius, in fact it has been placed in several genera. This is an annual fungus appearing on dead conifers in North America and also in Europe, where it is called the Conifer Blueing Bracket.

Postia subcaesia, syn.: Oligoporus subcaesius, Tyromyces subcaesius, Spongiporus subcaesiusBlueing Bracket, Blauer SaftporlingSlo.: modrikasti skutovecDat.: Oct. 09, 2013 Lat.: 46.39815 Long.: 13.70048Code: Bot_759/2013_DSC8535Habitat: Mixed forest, Picea abies and Fagus sylvatica dominant, almost flat terrain, calcareous ground; full shade; humid place, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 4-6 deg C, elevation 1.000 m (3.300 feet), alpine phytogeographical region.Substratum: on dead rotting branch lying on ground and on rotten half buried roots of Fagus sylvatica, partly still in bark.Place: Zadnja Trenta valley, left bank of (mostly) dry Soa river bed, north of Bavki Grintavec mountain, East Julian Alps, Posoje, Slovenia EC Comments: This observation was first determined as Postia caesia (see former text in brackets below). But, a kind explanation of Mr. Gnter Sturm, Germany, having long 'mileage' in Polyporaceae, and the paper of David (1974), Ref.: (8) convinced me that the correct determination should be Postia subcaesia. Now substratum fits better. Also habitus of the find fits better to the new determination. Pileus of P. caesia is of more uniform colors and never as strongly zonate as in this observation. Another trait, which fits better now, is the fact that the pilei color didn't changed distinctly blue when bruised. Nevertheless, spore dimensions still don't fit to data from literature. May be Ryvarden's comment in Ref.: (7), p 405, regarding distinguishing both species: 'However, there are some disturbing intermediate specimens on hardwoods.' explains the situation?Former text:[This beautifully blue polypore could eventually be Oligoporus subcaesius. Unfortunately, the distinguishing traits between O. caesius and O. subcaesius seem to be treated quite inconsistently in the literature available to me. Oligoporus caesius should principally thrive on wood of conifers (with rare but documented exceptions) and should have spores wider than 1.5 , while Oligoporus subcaesius is found on broadleaved trees and should have spores narrower than 1.5 (as per Ref.:(5) and Ref.:(1)). Contrary, Ref.: (4) states narrower than 1.5 spores for O. caesius (a typo?). Also the information about spore shape (allantoid versus cylindrical) is inconsistently given in different sources. In this observation measured spore width speaks in favor to O. caesius (according to Ref.:(1) and (5)), while substratum doesn't support this decision. Since exceptions with regard to substratum are known, and based on quite distinctively blue color of the pilei and their size (O. subcaesius should be significantly larger according to Ref.:(1)) I decided for O. caesius, but this may be incorrect. ]Growing in a small group of about 6 pilei of different size; pilei up to 6 x 4 cm across; flesh soft, fibrous; SP very faint, whitish(?), oac857(?).Spores smooth, cylindrical and moderately allantoid.
