Similar in appearance and ecology to T. gelatinosa. It more commonly grows on organic substrates, as epiphytic, epibryophytic or lignicolous. It is well recognizable due to characteristic orange pigments (antraquinones), but they are sometimes missing. Those underdeveloped specimens are difficult to distinguish from e. g., T. viridescens, which also contains gyrophoric acid (soralia C+ red). Trapelipsis pseudogranulosa is quite common in more humid areas all over the Czech Republic. Regionally, for example in certain parts of Northern Bohemia, it is a common epiphyte on acidic tree bark at river banks in shaded valleys. It survived successfully even in heavily polluted areas.taxonomic classification:
