Phaeographopsis palaeotropica Kalb & Frisch View in CoL in Kalb (2004: 313). ( Figs. 2C, 2D View FIGURE 2 )

Distribution and habitat:—Reported from Africa, Republic of Cameroon ( Kalb 2004), Papua New Guinea and the Philippines ( Aptroot et al. 1997, as P. indica ), and also found in Thailand, growing on bark of unidentified trees in lowland rainforests, swamp forests as well as in dry evergreen forests.

Material from Thailand examined:— Prachuap Khiri Khan province: Bang Saphan district ; tambon Mae Rumpueng, Pa Klang Ao Forest Park, in a disturbed dry dipterocarp forest ( Dipterocarpus alatus ), on bark of various trees, 15 m, 11°12’36’ N, 99°31’25’’ E, 20 December 2015, J. Sutjaritturakan & K. Kalb (Hb. K. & J. Kalb 41922, 41395, 41398) .

Remarks:—Of special interest is the collection Hb. K. & J. Kalb 41395, cited above, because the discs of the ascomata which are usually black and mostly covered by a greyish pruina are greyish or beige below the pruina, due to non-desintegrating asci. In this specimen the spores remain within the hymenium and no mazaedium is formed. This specimen looks exactly like a Diorygma , but recent molecular studies ( Rivas Plata et al. 2013) show that the two genera are not closely related. In the phylogenetic tree (loc. cit.), Phaeographopsis is sister to Diploschistes . A close relationship of these two genera was originally proposed by Kalb (2004) due to the similar spore- and ascus-types.
