Under Panaeolus cyanescens is the most common type in the concurrent involvement of spores size and number of subgenus Copelandia. It differs externally by its pale sterigmata at the Basidia (usually there are 4) the fungus can coloration. Due to this fact the bluing of the fruitbodies be well defined.

The left dried mushroom is missing accurate picture of his mushroom. The Panaeolus Metuloids, while the Spore dimensions are almost ("Agaric papillonace") shown in this table is a kind identical. But I found Sulphidia on the surfaces of the gills. without Metuloids and therefore not identical with those Therefore the left fungus is Panaeolus rubricaulis, later which BRESADOLA meant. In any case, BRESADOLA described by PETCH (1925) from Sri Lanka. misread BULLIARDS table. Therefore the name BRESADOLA (1913) has underlied the name Agaricus Papilionaceus Bull. cannot be applied to BRESADOLAS papilionaceus in the summary of the genus Copelandia fungus. Bull, but examined material from the Philippines collected For a long time there was only one kind with Metuloids by COPELAND (COPELAND 344). known, namely Panaeolus cyanescens (Berk. & Broome) This material can’t be found anymore. Only later, Sacc. It is also by far the most common, among others in BRESADOLA (1931), quotes BULLIARDS Tf 561, fig. 2 this group, characterized by a predominantly pale cap.

SINGER, in WEEKS et. al.

Gathered from the only some cohesive stem material is left. Nevertheless, identification key according to SINGERS view, missing clamps in the Fig. 18: Panaeolus affinis, New Guinea, Horak (ZT 71/340): a: Spores, b: Cheilocystidia, c: Metuloids, d: Basidia. 41 I was able to find the typical Metuloids (dimensions Distribution: approximately 47-55 x 13-19 μm), 4-spored Basidia and Only known from New Guinea (Asia) so far. spores analogous to the dimensions of cyanescens (11-14 x 8-11 x 6,5-7 μm) in this mushroom dust. At the cap hyphae Classification: the clamps were clearly visible, although very sporadic and This type differs from P. cyanescens mainly by its smaller indistinct. The complete absence of clamps can’t be judged spores. P. lentisporus is very similar, but can be separated by on such a sparse amount of material. I don’t think it is spores more flattened in proportion to their length and enough argument to recognize the two types only by this broader spores which have an extremely squarrosing Germ feature anyway. pore.
