glabrum, P. spinulosum

and P. subericola sp. nov. were very similar to each other. All Lazertinib datasheet species were predominantly monoverticillate, with vesiculate conidiophores and 6–12 ampulliform phialides. The main microscopical difference was the conidia ornamentation, this website which was smooth to slightly rugose in P. glabrum and P. subericola sp. nov., and distinctly rugose in P. spinulosum. Moreover, the conidia of P. subericola tended to be more rugose than in P. glabrum and the conidiophores of this species occasionally were branched, a character not observed in P. glabrum and P. spinulosum. Extrolites analysis The majority of the strains assigned to P. glabrum, P. spinulosum and P. subericola produced a pattern of extrolites typical for each species (see Table 2). The P. glabrum isolates

had a typical extrolites profile containing asterric acid, bisdechlorogeodin, sulochrin or citromycetin, while isolates of P. spinulosum produce asperfuran, palitantin and frequentin. Asperfuran, deoxybrevianamide E and unidentified compounds which were tentatively named AMF were found in the P. subericola. These AMF compounds are indols with an extended chromophore similar to penitremone. Two cork isolates which phylogenetically clearly belong to P. glabrum (CBS 126333 and 127701) were chemically weak and show no detectable extrolite production.
